It is hard to imagine how pilots managed to find their way through fog, rain, sleet, and snow prior to the advent of instruments that could indicate whether the airplane was flying straight and level or spiraling toward the ground. Some flyers were good enough in most situations to sense attitude even without an outside-the-cockpit visual clue. However, it is entirely possible to enter into a situation where your senses cannot possibly tell the difference between normal flight and a life threatening scenario. Albert Einstein's General Theory of Relativity tells us that without knowing otherwise, there is no discernable difference between gravity and physical acceleration. Therefore, a pilot in solid Instrument Flight Rules (IFR) conditions where he cannot see the sky or ground could very well mistake the acceleration of a coordinated turn or a climb for the acceleration of gravity, and then react improperly in a manner that rather than correct the situation, make it worse. Many a pilot, even in today's world, has succumbed such a terrible fate.
Scale Model Instrument Panels for IFR
Flying by instruments is quite the most important accomplishment for pilots these days - and for the time to come. No longer must an airman depend upon his sight and hearing to tell whether he's flying upside down or whether the motor is coughing and losing revs. Delicate instruments, calibrated to operate at utmost efficiency, are the mainstay of aviation's future progress. For they tell us what we want to know both on the ground and in the air.
Below is an array of common type instrument boards. For the scale modeler, this should be of great help. He can trace or copy the type panel best suited for his scale model. Type "A" "B" and "C" are usually found on heavier single engined craft such as Bellancas, Stinsons, Wacos, Lockheeds, Vultees,' and others.
Simple panels "D" and "H" are found in light planes, Cub, Luscombe, etc. Packed boards such as "E," "F" and "G" are usually installed in medium or large twin engined craft, Douglas, Lockheed, Consolidated, Beechcraft, Cessna, to name a few. Panels "I" and "J" can be found in medium size single engine jobs which have dual controls and where the board is situated on either side of the pilot's seat. These instrument board designs are merely a representative group. Other designs do not vary much in layout.
