Flight Test is a measurement process taken under flying conditions from various air vehicles (i.e. aircraft, helicopter, UAV, missile etc.) to collect data needed for flight performance checks, system certification and intermittent failure analysis. Flight Test has a broad application in aviation field during production, upgrading, or major modification phases and diagnosing of intermittent failures, which occur only in flight. Flight Test requires mainly three sub systems:
- 0/B System (mounted on air vehicle)
- Data Link
- Ground Station (Flight Test Center -FTC)
0/B system collects data from parameters to be measured by using various sensors and data acquisition system located on the air vehicle. Then this data is transmitted to the ground station via a telemetry transmitter. Ground station continuously receives and converts the RF signals to a proper data format. Formatted data is recorded and analyzed at the same time by the FTC.
