Flying Qualities (FQ) and Handling Qualities (HQ)

Flying Qualities

Calspan Aerospace has been in the forefront of Flying Qualities (FQ) and Handling Qualities (HQ) research and instruction since modifying an F4FU Corsair into a variable stability aircraft in 1948 as Cornell Aeronautical Laboratory (CAL). Subsequent variable stability aircraft included the NT-33 Shooting Star, Convair 580-based Total In-Flight Simulator (TIFS), and USAF F-16 Variable Stability In-flight Simulator Test Aircraft (VISTA). Today, commercial FQ and HQ instruction is conducted in Calspan’s variable stability Learjets.

Calspan Aerospace supports aerospace industry innovators by teaming with six of the seven SETP-recognized test pilot schools to provide world-class airborne instruction in Flying Qualities and Handling Qualities. We also offer short courses in FQ/HQ taught at our state-of-the-art flight test facility located at the Niagara Falls International Airport.
