To insure the accuracy and fidelity of the simulation, A2A developers have been privileged to take flights in carefully and lovingly maintained B-17’s today with eyes and ears wide open. With multiple cameras rolling and microphones in hand, A2A developers crawled within every nook and cranny of the cockpit so that every sound and sight that a B-17 Pilot would experience is there for you, right down to the wind rushing over the airframe and the characteristic vibrations and tremors of the real aircraft.

As you have come to expect from A2A Accu-Sim aircraft, nothing has been left out that operates in the real aircraft. In fact, there are many features that are included in this simulation that have never before been modelled or included in any other aircraft simulation.

What this means is that when you are flying and operating the A2A Accu-Sim B-17G you will have the uncanny feeling that you are actually in command of a real world B-17. If the engines and the various systems of the simulated B-17 are not operated correctly and as the aircraft manual provides, the airplane will perform less than optimally, and if taken to the extreme, damage and failures will occur just as they would under similar circumstances in the real world.

Occasionally, parts of the airplane will become worn or fail from ordinary use, just as occurs in a real airplane. There is a complete and comprehensive maintenance hanger that you can take your airplane to when on the ground with engines shut down. There you will get a fully detailed, written and illustrated report about the condition of the airplane, and can then authorize recommended repairs. When in the maintenance hanger you will hear typical noises of a repair facility echoing around the vast space such as machinery running, parts and tools falling and clanging to the floor, etc. This kind of intense, authentic pilot experience helps to gives you a sense of total immersion and involvement in day to day life with such a magnificent airplane.

The electrical system seems as if it has actually been wired and hooked up and consists of the lights, landing gear retraction system, flaps, turbochargers, fuel pumps, bomb bay doors, radios and more. They are all electrically powered by the batteries, generators and even an Auxiliary Power Unit (APU) which you can order one of your waist gunners to turn on and off. The voltmeters’ readings vary authentically as each item is brought on or taken off line, and as each of the three independent batteries are selected to be read. Electric motors whine with their own unique, authentic sound. You can even hear the sounds of the hydraulic pumps and fluid rushing through the pipes. Vital batteries, motors, and pumps can unexpectedly fail which will test your metal as pilot in command. As a result of this realism, you will get used to going to the maintenance hanger before each flight the see what needs to be done to keep your B-17 in safe and reliable flying condition.

Your crew is interactive and various crewmen will speak to you from time to time to remind you to do various things that you may have forgotten to so (see “THE CREW” below). The Flight Engineer watches the engines and may remind you to give the guys in the back a little heat and your Co-Pilot can even manage the engines for you. If you fly the airplane too roughly, you may get complaints from the crew. Your landings may get compliments if they are good and the reverse if they are not. Various crewmen will report to you as to the position of the landing gear and flaps when you raise or lower them. You are definitely not alone when you are the pilot in command of a capable crew.

Every aspect of the engines and the fuel system has been faithfully modelled as well. Fuel is supplied through gravity-fed tanks, through electrical booster pumps, mechanical fuel pumps, transfer pumps, to large, thirsty rumbling radial engines.

You can select the grades of the fuel and oil to be used on each flight, which will appropriately change how the engines perform. Loading the bird with fuel and feeding one tank with fuel from another in flight is fully functional and accurate in operation to the actual aircraft. You can also cross feed fuel from tanks in one wing to tanks in the other wing. You can opt to carry a centre fuselage bomb bay fuel tank for extra range, or bombs, as you choose.

The cowl flaps and inter-cooler doors are fully adjustable; and just as with the propellers, you can set them yourself, or command the Co-Pilot to do it. When you command him to monitor these functions, he will continually set them to keep the engines running cool and at their peak.

The B-17G has a unique turbocharger control — a numbered wheel for pre-setting the maximum amount of manifold pressure desired when the throttles are fully opened. In the A2A Accu-Sim B-17G you will find this turbocharger control fully and authentically modelled in every detail exactly as in the real world B-17G. You can even calibrate individual turbochargers, just like the real pilots and crew-chiefs do, so that each engine will almost purr in harmony with another.

The Pilot’s and Co-Pilot’s left and right side windows can be opened to any amount desired. They will fog up if not vented properly, or if the cabin heater is incorrectly set for the outside air temperature.

From time to time, your radioman will contact you on the intercom to well you that he has picked up something that you might like to hear and that you should switch to the “liaison” channel of your com radio. When you do this, you might hear a song, a news program with a speech by Winston Churchill, a sports report, or some other radio program that would have been broadcast over the radio in Europe during WWII. These recordings are all taken from authentic 1940’s broadcasts. At first you will hear static as you approach the station, then the program will get clearer; and, as you fly away from the station, you will hear static again until the program cannot be heard anymore, as if it was really coming in on a low frequency radio band typical of those days. As you go out of range of the broadcast, the radioman will comment on that. This is a real first in flight simulation, and it adds an uncanny sense of realism, depth, time and place to your sim experience. It’s one of my favourite parts of this incredible simulation, and it is a remarkable A2A flight simulation first.

Another nice touch is the feature which allows you to open the bomb bay doors or command the bombardier to do so, and drop the bombs. From the outside, you can watch them fall away, or from inside, you can hear the latches release as your aircraft instantly becomes 6,000 pounds lighter. You can also jettison your internal bomb bay tanks if you wish, which make a characteristic ‘whoosh’ as those enormous, tall tanks fall into the airstream below.

Here’s a real treat for aviation historians and everyone who loves the B-17: A2A has modelled a fully functional, completely accurate and authentic Honeywell 1-C automatic pilot in this simulation. When you access it through 2D pop-up, you will find an exact replica of the C-1 control panel upon which every knob and switch operates and functions exactly as did the real one. Also, you can communicate through the 2D panel with your bombardier, who was a necessary team-mate when operating of this piece of equipment. While this very early auto-pilot was finicky and did not have the simplicity of operation or many of the features of the more modern auto-pilots that we have become accustomed to using, operating this C-1 simulation will let you share the experience which Pilots of the B-17 (as well Pilots of the B-24 and B-29) had when they used this historical piece of aviation equipment. A2A’s fully functioning model of the C-1 is but another of the many ground-breaking flight simulation firsts contained in A2A’s Accu-Sim B-17G simulation.

The flight model of the A2A Accu-Sim B-17G has been meticulously created to give you the true feeling of flying this heavy, four-engine bomber. Close reference to B-17 Pilot’s reports and A2A staff flights in a real B-17 have informed us to the greatest extent possible what flying this airplane feels like. That enormous fin and rudder made turns very smooth and easy. The elevators were sensitive and never lost their effect, even at slow speeds. There was power to spare in those four Wright R-1820-97, 1,200 horsepower engines. Accordingly, the “Fortress” carried herself with grace and ease at all times. Altogether, she was a majestic and gentle airplane and every B-17 pilot we have spoken to and every pilot’s report we have come across has said without reservation that she was a joy to fly.

The A2A staff has meticulously and professionally recorded every sound that is heard when operating and flying a B-17G, from the powerful engines to the smallest switch in the cockpit. The airframe groans if you strain it too hard, the wind whistles outside according to the airspeed and, if you open either or both of the cockpit windows you will hear the engines louder outside the window and hear the wind whip into the cockpit, just as with the real airplane. The brakes and tires squeal appropriately when they are pushed hard. Every control, switch, knob and device that makes a sound in the real-world B-17G has been recorded and included in this simulation in order to immerse and involve you as completely as possible. Switches and knobs click from position to position with a visceral feel that is uncanny. Everything in the cockpit moves and operates exactly as it does in the real B-17G.

All of these features and much more await you in the A2A Accu-Sim B-17. This is not a generic “B-17”, and this simulation is not like any other you have ever experienced before. Great care has been taken by A2A to replicate the actual “G” model of this airplane. It is historically accurate down to the rivets, instruments, handles, controls, cables, wires and tubes of the B-17G. Nothing has been left out and everything moves and operates authentically. A2A’s exclusive and proprietary Accu-Sim matrix provides features and controls far beyond that which the host platform normally allows. That is why A2A has been able to create the most accurate, historically correct and complete simulation of the B-17G ever offered.

Even if you have never actually seen a Cub in the flesh (and this is getting harder to do every year), if airplanes are your game, you have a good idea of what a Cub is all about. Virtually every pilot has flown or knows someone who has flown a Cub.

If you throw a baseball, a paper airplane, and a stick into the air, each would behave differently based on it’s weight, density, and shape. Each will interact with the air and ultimately the ground very differently, just as we would expect. But what if you dropped a tennis ball on a hard surface, and instead of bouncing, it just hit the ground with a loud ‘clunk’ and stopped? We are physical beings that live in a world that has certain truths we take for granted, that is until they are gone. However, in a simulated world, nothing can be taken for granted. In fact, if the physics in a simulated world are not specifically created by someone, they simply do not exist. With Accu-Sim, we have built-in to this simulation many of the physical rules that we know to be true and which we expect to exist in the real physical world.

For example, if you start a simple engine that is cold, you expect that it will run rougher and less reliably than when it is warmed up. If one morning you start your cold engine and something seems different, if it does not behave as you expect it to, you will notice this and your senses will tell you, “something is not right.” This is because you have become accustomed and comfortable with how your aircraft responds at all times, not just in the behavior of a single gauge, but in subtle ways — the way the engine sounds and responds to the throttle, the way the body squeaks, or even in the way the air sounds as it passes by your airframe at different airspeeds. More obviously, if you taxi on the grass, you expect your aircraft to buck and dip as it moves over bumps and depressions in the ground. Similarly, you would also expect to sway and rock if sitting on unsettled water in floats. All of this, and much more, will be experienced and brought to you more accurately and realistically by Accu-Sim. Now it’s an entirely new and more real world. It’s a world that makes you believe you literally have a physical piece of equipment stuffed inside your computer monitor because all of these little physical truths which cause actions and reactions, and which you notice when they are there or not there, have been created in Accu-Sim. It is all of these little clues which we experience and observe, and which we take for granted in our real world, which make things seem real to us. When they are missing or portrayed inaccurately, things just don’t seem right. You know it; you sense it, and so do we.

Perhaps the most important thing this little airplane will bring to you is honest, true-to-life stick-and-rudder flying, something pilots often forget after flying large, heavy, fast, complex aircraft for a while. You will be actively engaged in flying this Cub almost all of the time. After just flying it for a very short while you will start to feel like a better pilot, and you will be.

Part of the secret of the P-40 was in it’s rugged Allison engine and its high dive speeds. Some squadrons pushed it’s capabilities well beyond its official limits in combat. This high power matched with an air frame that held onto energy better than the Japanese counterparts, meant an experienced pilot could command the fight. He could decide when to engage and when to escape. When we read about Middle East and Australian squadrons over-boosting their Allison engines, we couldn’t wait to Accu-Sim this bird and experience it ourselves. This resulted in us digging even deeper into not just the function of this engine at such high power levels, but the sound.Additionally, other systems like the P-40’s unique hydraulics required us to take our Accu-Sim to yet another level of detail. You may notice when a fighter raises it’s gear, the gear sometimes comes up at different times. Instead of us simply and without condition, telling the aircraft to raise the gear one leg at a time, we decided to dig deeper and create the entire underlying system, allowing whatever behaviours be the result of actual systems at work. In fact, this is the philosophy behind Accu-Sim from the start. Build it right, and enjoy the experience. When looking to the construction, the newest modelling and advanced material-making techniques results in an aircraft that you can just spend not just minutes but hours admiring the beauty of the shape and look of the aircraft. Together, with professionally recorded sounds and physics, the end result is the sense of having a complete, real, majestic, raw, flying machine stuffed inside your computer. We hope you enjoy your new beautiful bird, and hope you learn to fly and treat her well.

Yet we all interpret life around us differently, including how an airplane feels to each pilot. It is up to us, at A2A, to not just create an airplane that objectively performs in line with the actual airplane, but to capture that human feel and interaction with the real airplane. We have to somehow magically capture that experience that applies to all pilots. And Accu-Sim technology allows us to achieve this better than anything we’ve used before.

Beyond modeling a specific airplane, the Bonanza history is surrounded with tales and stories developed over many decades, some are true and some not. Probably the most common nick name the Bonanza V-tail is known for is being the “doctor killer.” When the Bonanza was first introduced, it was unlike anything anyone has ever seen in the general aviation market. And for the decade following it’s release, successful businessmen and professionals were buying the Bonanza in great numbers. Many of these pilots had primary careers that demanded a great deal of their time, not leaving much room for flying. And like many “weekend warriors” today who spend the whole week sitting behind a desk then go out and play a sport on the weekend, injuries erupt. The same holds true for the busy professional working all week who then decides to occasionally fly a high performance airplane like the Beechcraft Bonanza V-tail.

The V-tail Bonanza was built from World War II fighter technology, which was designed for highly trained professional pilots. And like most Warbirds, the Bonanza want so fly fast, all the time. Unlike general aviation aircraft that were  developed in later years to have benign flight characteristics, the Bonanza inherently has all of the challenging qualities of the World War II fighter. From my point of view, flying a Bonanza is just like flying a Warbird. It rumbles, shakes, rattles, is heavy and can bite the low time pilot in a heart beat. Therefore it’s this writer’s opinion that the new pilot should approach flying a V-tail Bonanza exactly the same as approaching an aircraft like a P-51 Mustang. The V-tail Bonanza, like the Warbird, is designed for experienced pilots who take the time to study and fly and operate such an aircraft with organization, patients, and preparedness.

For those pilots who do approach the V-tail Bonanza with the respect it deserves, it will reward the pilot with an experience unlike any other aircraft in the general aviation fleet today. It is for this reason the V-tail Bonanza still stands alone today, as it did on the first day it was introduced to the public.

We hope our work on this aircraft meets and exceeds all of our customers expectations, and also hope this aircraft delivers not weeks or months, but years of excitement, wonder, surprise, and the most complete simulated aviation experience to date. Thank you to all of our customers for allowing us to pursue our dreams, and hopefully help pass our dreams onto you too.

The biggest challenge we now faced was the demand for more Accu-Sim aircraft. The problem is, it was simply not possible to quickly deliver aircraft on this level of detail, however, our rate of delivery / quality of product is unsurpassed in the industry. This is a large reason why Accu-Sim has been so successful. Over the years, we released a P-47 Thunderbolt with a complete cockpit sound set, a Piper J3 Cub where you hand-start the engine, and the new core series of Accu-Sim birds (Supermarine Spitfire, P-40 Warhawk, and P-51 Mustang). We also released a later Captain of the Ship add-on to our flagship, Stratocruiser. Still, customers demanded more.They asked “Can you Accu-Sim FSX?” and our answer was always “this is just not possible.” Well, over the years and now with all this technology behind us, we found a way to get, what we call “A touch of Accu-Sim” to FSX. In early 2012 we released this new concept, and called it “Accu-Feel.”The name Accu-Feel was chosen because this best described what this product does. We managed to hook into the lower core of FSX using our Accu-Sim technology, and were able to make things happen without touching a single file in the FSX directory. This was critical because the program had to work in a way without interfering or altering 3rd party content. Our goal was to allow Accu-Feel to intelligently set itself up for any aircraft, yet also allow the customer the final say on everything by way of an easy-to-use in-game user interface.Accu-Feel launched out of the gates unlike anything we have ever released before. It rocketed to #1 in online stores and just sat there for months. Today, almost one year later, it remains in the top ten. The reason is simple – customers / pilots were having fun with an all-new, powerful sound system and how it translated physics back to them. They also appreciated a program that worked hard for them, so they could just fly. And technically, Accu-Feel was solid and reliable. We had a winner.Now we have the next generation of Accu-Feel, version 2, Air, Land and Sea. A quick read of this manual will show a lot of new and exciting features that we hope you come to love as much as we did in making it..

The Spitfire was designed by R. J. Mitchell, an aeronautical engineer of stellar talent who had previously designed such aircraft as the Supermarine S6B, which won the Schneider Trophy in 1931. Borrowing from the developments of others, including the low-wing, monocoque design which came from the United States, Mitchell crafted a superb basic design which stands to this day as one of the greatest piston fighters in aviation history. Mitchell envisioned a light, maneuverable craft with low drag, elliptical wings, and a broad performance envelope. The result was the Spitfire, a capable, lethal, yet forgiving aircraft that ultimately proved more than equal to anything the Germans could throw at it, including the vaunted Focke-Wulf 190.
The Spitfire had a number of design characteristics which set it apart from other contemporary fighter aircraft. The Merlin engine, the elliptical wing, the well-harmonized controls, and the versatile wing platform all worked together to create a package that was perhaps unmatched in terms of its immediate effectiveness and its potential to be developed further. Unlike the Japanese Zero, which was obsolete by 1943, the Spitfire was just coming to its prime. Chief among the features that set the Spit apart from other aircraft was its wing, which served multiple purposes. The elliptical planform and relatively broad root chord allowed a thinner airfoil section, reducing drag while preserving lift, which led to a very low wing loading. This increased top speed, preserved a low stalling speed, increased the service ceiling, and provided excellent low-speed agility. But the broad wing chord also allowed the convenient fitting of formidable armament such as multiple 20mm cannon and heavy machine guns.

The Spitfire last saw combat in 1948 during the Arab-Israeli war, where Spitfires from both sides were pitted against one another. But the honor which will always distinguish this singular aircraft is its superb service during the Battle of Britain, where it — along with the Hawker Hurricane — helped to fend off German designs for invasion of Great Britain. For that, it will always be remembered.

What is the philosophy behind Accu-Sim?
Pilots will tell you that no two aircraft are the same. Even taking the same aircraft up from the same airport to the same location will result in a different experience. For example, you may notice one day your engine is running a bit hotter than usual and you might just open your cowl flaps a bit more and be on your way, or maybe this is a sign of something more serious developing under the hood. Regardless, you expect these things to occur in a simulation just as they do in life. This is Accu-Sim, where no two flights are ever the same.

Realism does not mean having a difficult time with your flying. While Accu-Sim is created by pilots, it is built for everyone. This means everything from having a professional crew there to help you manage the systems, to an intuitive layout, or just the ability to turn the system on or off with a single switch. However, if Accu-Sim is enabled and the needles are in the red, there will be consequences. It is no longer just an aircraft, it’s a simulation.

Actions Lead to Consequences
Your A2A Simulations Spitfire is a complete aircraft with full system modeling. However, flying an aircraft as large and complex as the A2A Spitfire requires constant attention to the systems. The infinite changing conditions around you and your aircraft have impact on these systems. As systems operate both inside and outside their limitations, they behave differently. For example, the temperature of the air that enters your carburetor has a direct impact on the power your engine can produce. Pushing an engine too hard may produce just slight damage that you, as a pilot, may see as it just not running quite as good as it was on a previous flight. You may run an engine so hot, that it catches fire. However, it may not catch fire; it may just quit, or may not run smoothly. This is Accu-Sim – it’s both the realism of all of these systems working in harmony, and all the subtle, and sometimes not so subtle, unpredictability of it all. The end result is when flying in an Accu-Sim powered aircraft, it just feels real enough that you can almost smell the avgas.

Your Aircraft Talks
We have gone to great lengths to bring the internal physics of the airframe, engine, and systems to life. Now, when the engine coughs, you can hear it and see a puff of smoke. If you push the engine too hard, you can also hear signs that this is happening. Just like an actual pilot, you will get to know the sounds of your aircraft, from the tires scrubbing on landing to the stresses of the airframe to the canopy that is cracked opened.

Be Prepared – Stay Out of Trouble
The key to successfully operating your Spitfire, or any high performance aircraft for that matter, is to stay ahead of the curve and on top of things. Aircraft are not like automobiles, in the sense that weight plays a key role in the creation of every component. So, almost every system on your aircraft is created to be just strong enough to give you, the pilot, enough margin of error to operate safely, but these margins are smaller than those you find in an automobile. So, piloting an aircraft requires both precision and respect of the machine you are managing.

It is important that you always keep an eye on your oil pressure and engine temperature gauges. On cold engine starts, the oil is thick and until it reaches a proper operating temperature, this thick oil results in much higher than normal oil temperatures. In extreme cold, once the engine is started, watch that oil pressure gauge and idle the engine as low as possible, keeping the oil pressure under 120psi.

The oil and coolant temperature gauges are critical throughout your flight. Idling too long on the pavement will overheat this Spitfire because it’s cooling radiator is inadequate. Plan to be off the ground in under ten minutes. Don’t let your engine exceed 100 degrees Celsius before your takeoff roll.

Once airborne, you will want to avoid steep climbs, especially in hot weather, to keep good airflow to your radiator. You will also want to keep your radiator opened at all times during flight, adjusting it to maintain temperatures around 100 degrees if possible, never more than 120 degrees. High engine power increases both water and oil temperatures, but oil is also heated up quite a bit by engine friction (RPM). So if you are running hot oil temperatures, you may wish to also decrease your engine RPM.

The “Connie,” as it was universally and affectionately called (much to the dismay of Eddie Rickenbacker of WWI fame who, as the owner of Eastern Airlines, thought the name to be too effeminate) was a spectacular and singular aeronautical design from the first rude sketch of “Excalibur” to the last L-1649 “Starliner.” Gathering many firsts and breaking many records in its almost five decades-long useful lifetime, Constellation consistently stands out from her sister airliners both visually and functionally. Sadly, the many luminous stars embodying this “Constellation” were ultimately eclipsed when at their brightest by the urgent, inexorable force of progress which saw the end of the age of the long-distance piston engine airliners and the birth of the big, jet-powered transports. This new era of air-transportation in the U.S. Began on 26 October 1958 when Pan American Airlines (Pan Am) flew a Boeing 707 with 111 passengers from New York to London. Soon, the jet-powered Douglas DC-8, Convair 880 and Sud Aviation “Caravelle” joined the 707 and long-range piston airliners were through.

Even so, there are many, this writer among them, who posit that even whilst swifter, no kerosene burning aluminum tube has ever come close to matching Connie’s superb grace and poise. Her story is full of ironies and surprises, of Geniuses, Presidents and Pioneers. You see, there once was this fabulously wealthy, incandescently brilliant, eccentric movie mogul, aviator and airline owner who had an idea for an airplane… – Excerpt from Constellation manual history by Mitchell Glicksman © 2016

Lycoming 540 engine
Most A&P mechanics refer to the Lycoming 540 as being “bulletproof.”  Consider that a Chevrolet big block in an early ‘70’s Corvette is 454 cubic inches, a Skyhawk’s engine is either 320 or 360 cubic inches (like small automobile V-8).  The Skylane engine is 541.5 cubic inches, which is bigger than the previously mentioned Chevy big block.   I have the same engine in my Comanche, and you feel this 50% bigger engine under the hood, just rumbling and rattling, waiting to be opened up on takeoff.  We expanded Accu-Sim to capture the more aggressive nature of operating such a nice and powerful GA engine.

Constant speed prop – propeller physics
We upgraded the propeller physics for the Skylane in several areas.  This was necessary to deliver the best experience when operating this new system.  For example, many people don’t realize that a 2-blade propeller will generally cruise faster than a 3-blade at all but the very highest altitudes (and I’m talking where oxygen is required).  The Skylane manual is based on the 3-blade, so you can squeeze out even more speed by using a 2-blade.   The high cruise is just around 167 mph with a 3-blade, and around 170 mph with a 2-blade (keep in mind every plane will have slightly different cruise speeds, which speaks to the uniqueness of each airframe, engine, and prop).  However, the 3-blade propeller will, in general, pull harder off the line and perform better in steep climbs.  We also improved the modeling and sound of the propeller when it both flattens out and cuts into the air, which is most noticeable during prop checks on the ground.

Cruise management – beyond the book
This was an unexpected, but pleasant discovery when making the Skylane:  Our cruise performance accuracy actually exceeds the pilot’s manual.  Yes, we’re actually better than “by the book.”  This is because some figures in the POH are calculated / estimated.  For example, in Accu-Sim, you can realize the benefits of flying at lower RPM’s with higher manifold pressure, or “over square” (higher manifold pressure X 100 than RPM).  Some pilot’s are still being told today that running a modern GA engine over square is bad, which is a technique recommended on some older, larger radial engines of the past.  The fact is that most engines run better and more efficient at lower RPM and higher manifold pressure, rather than high RPM and low manifold pressure (just make sure you follow the guidelines in the pilot’s handbook for the airplane).  Accu-Sim models this efficiency, and we confirmed this on our actual flight tests.  So, you will be experiencing the same differences from the POH with Accu-Sim than with the actual airplane.  You will also find yourself thinking hard about your mixture, how it affects your cruise performance, temperatures, economy, etc., just like in the real aircraft.  Just make sure, any real world pilots out there reading this that you follow the recommended cruise settings for your airplane because there is a limit to how much manifold pressure you are able to use at certain a RPM.  Also, some engines require you to avoid certain power settings / RPM ranges due to vibration and balance issues.  There is no one size fits all approach, but this Accu-Sim Skylane will certainly help both pilots and sim enthusiasts learn better flying skills and engine management practices.

Cowl flaps and advanced combustion physics
We further researched and developed engine temperatures, both cylinder head and exhaust gas temps.  We also re-formulated the impact of mixture on the process and temperatures.

Expanded physical sound
The starter physics, engine starts, shutdowns, and in flight physics are pushed even further.  Try playing with the throttle, or kicking the rudder at speed or doing a prop check.  It’s a world of wonderful physics that drives our sound engine.

Hand towing
We added a new feature, turning your flight stick or yoke into a tow bar.  It really gives the feel you are moving a large plane around, and you can put it exactly where you want it, however you wish.  Our own Captain Jake said the other day “This towing is fun!”  That’s a good sign coming from a 14 year old.

The entire PA-28 Cherokee line from the humble two- seat 150 h.p. PA-28-140 to the swift, retractable undercarriage PA-28R-200 Arrow, to the powerful, heavy load-carrying 235 h.p. PA-28-235 Dakota, is respected as being one of the most popular, commercially successful series of aircraft containing within some of the most pilot-friendly aeroplanes ever built. Each member of the Cherokee family fills its particular niche at least as well as, and often better than other aircraft of similar type. However, of all of the many Cherokees the Cherokee 180, sitting as it does right in the middle of the pack has proven itself to be most popular and justifiably so. Introduced to the public in 1961, the first Cherokee, the 150 hp PA-28-150 was immediately well-received setting the pace for its later siblings who went on to provide pilots of all levels of experience with honest, dependable and well-performing aircraft which are fun and satisfying to fly, reliable, safe and economical to own and operate. However, getting to this place took some time and some very astute business and aeronautical skills and sense.

No airplane personifies the epithet “Dynamic Elegance” more aptly than does the Piper Comanche 250.

The unique conjoining of many superlative aeronautic and aesthetic qualities marks this very special aeroplane. It has been said that if an aeroplane looks right, it will fly right. In this it is supposed that the eye’s natural ability to sense the pleasing proportion and intrinsic efficiency of a design is a reliable predictor of similarly excellent aeronautic performance. The Comanche 250 proves that this adage may be relied upon and bears validity. The Piper Comanche takes its well-deserved place on an illustrious list of aeroplanes which are both so very pleasing to the eyes and which are equally capable of superior performance.

There are many including this writer the most beautiful of all General Aviation (GA) aircraft, if not the most beautiful. From any angle the Comanche treats the eyes. This is what provides its elegance. Its superlative performance is a matter of record and this provides its dynamism. These two great and rare qualities, beauty and performance would be enough in and of themselves to place the Comanche at the pinnacle of GA aircraft, but the Comanche possesses an additional quality, one which, after all, may be its most endearing. Of all of the high performance GA aircraft the Comanche is arguably the least demanding of the relatively low- time pilot. That this is so is not an accident or a fortuitous circumstance – William Piper specifically intended that it should be so. The Comanche’s forgiving flight characteristics and its refusal to turn and bite an unwary pilot without plenty of warning, its relatively gentle stall, easy handling at low airspeeds and its overall delightful handling at all airspeeds are confidence boosters for its fortunate pilots.

The Comanche is also particularly exceptional in that it does not achieve its excellent aerodynamic performance at the expense of interior room and comfort; it is among the roomiest and most comfortable of “high performance” aeroplanes. Neither does the Comanche sacrifice useful load nor its generous weight and balance envelope at the altar of high airspeed. It is a highly capable heavy load hauler and its capacious useful load as well as its ability to safely carry baggage and substantial rear seat passengers without straining its aft load limits is far better than its closest competitors of equal horsepower – including and specifically the V-tail Beechcraft Bonanza. Perhaps most importantly, the Comanche does not achieve its performance by the intrinsic design features which compromise stable flying characteristics. Its light airframe weight and its generous, high aspect-ratio, laminar flow wing provides the Comanche with high efficiency as well as a low wing loading.

Accordingly, Comanche pilots and owners are particularly loyal and satisfied, and for good reason; the Comanche delivers extraordinarily dynamic performance while embodying the highest degree of aeronautic elegance.

So, how is it that all of these superlative qualities came together in this aeroplane? Well, therein lays the Comanche’s tale, one redolent of aeronautic expertise, prescience, confidence and also of a fierce competitive spirit. As it happens, it all began a little more than ten years before the first Comanche ever flew.

Once upon a time…

However, what all of these pilots who flew these aeroplanes, all of the celebrated aces and all of those who flew with them have in common is one aeroplane, one which is not nearly as well-known or popularly celebrated — the North American (NAA) T-6, or AT-6 as it was called in the U.S. Army Air Force (USAAF), SNJ in the U.S. Navy (USN) and U.S. Marine Corps (USMC), and “Harvard” in the Royal Air Force (RAF) and Royal Canadian Air Force (RCAF). Virtually every one of the pilots who flew against the Nazi and Imperial Japanese air forces, learned the art and craft of combat flying and honed their aeronautic skills to a diamond- sharp tip in the AT-6 before they were given leave to go into harm’s way in Mustangs, Hellcats and Spitfires.

Compared to those mighty and oft-heralded fighter aircraft, the relatively obscure AT-6/SNJ is the common bond that ties all of these pilots together and which enabled them to “go forth and vanquish the foe” so successfully. Many thousands of young, eager pilots owe their very survival in the mad swirl of aerial combat and the rest of their lives thereafter to the lessons they learned whilst in the cockpit of an AT-6, so successfully and profoundly did this humble aeroplane perform its role and do its duty.

If any aeroplane ever deserved to be called “classic”, then the venerable and ubiquitous Cessna 172 in all of its many variations surely deserves that title. It is a time-tested benchmark of aircraft efficiency, utility and excellence; it is one of the most recognizable aeroplanes (although sometimes mistaken for its larger and more powerful brother, the Cessna 182/Skylane and vice versa); its value has been and continues to be well-established and constant. The Cessna 172 has endured going- on six decades, and is an undisputedly traditional design. Classic? Q.E.D..
