The definition of flight test will vary as widely as the activity of those who are pursuing the subject. Perhaps the only consensus is that the vehicle be in free atmosphere as opposed to a wind tunnel or an enclosure. Scale models, unpiloted vehicles, tethered, or constrained vehicles are flight tested. The type of power or even the absence of power is not a decisive factor. Flight test may involve measurements, rely upon opinions, or simply be a demonstration of success or failure. This document will deal with flight testing of helicopters where it is necessary to record data which describe the vehicle operation and response to specified conditions and maneuvers. Individual sensors, systems, and recording devices must be incorporated into the test vehicles in a manner that will meet the data requirements within the known constraints. The total instrumentation system is best designed by starting with the data requirements. Accuracy, data quantity, reliability, and physical characteristics of the test vehicle are first considerations. Sensors can then be selected within cost, availability, and installation limitations. Characteristics of the sensor are evaluated to determine recording system requirements. Calibration schedules for sensors and systems can then be established.
