Without training or comparisons, it may be impossible for pilots to gauge the degree of compensation, especially with long-term programs and programs where handling qualities have improved gradually over time.
Test pilots need to constantly recalibrate their awareness of aircraft handling quality differences and compensation.
Pilots can learn to adequately fly poor aircraft with intentionally poor handling qualities.
The problem of aircraft handling exists because aircraft controls are counterintuitive.
These systems of high-order approximations generally do a great job of reproducing the handling qualities of the perfect aircraft; however, they result in a system that potentially is unpredictable to the operator and they introduce unpredictable response in the overall aircraft system (National Research Council, 1997).
