The FRL uses proven aircraft that are always flown within their certified flight envelope by certified pilots. Research programs are initiated only if they satisfy this basic requirement. Experiments are conducted on specially designed models, wing gloves, or extensions that do not compromise the flight characteristics of these aircraft. Thorough safety analyses and test procedures are completed prior to flight operations and all aircraft, regardless of FAA category, are maintained according to FAR 43.
Due to the sensitivity of test surfaces and instrumentation, flights are never conducted in rain, dust storms, or IFR conditions. Safety and aircraft integrity override all other flight driving factors. Flight testing requirements and operations are restricted based on safety considerations.
All models or airplane modifications will be subject to FAA approval and approval of a TAMU safety review committee. Moreover, the present contracts supported by AFRL and AFOSR require model and airplane modifications to be approved by the Air Force Safety Review Board and the Air Force Technical Review Board at Wright-Patterson Air Force Base.
