Flight Data Recorder (FDR)

Dedicated hardware for air data recording, directly connected to the autopilot for data reception and to the exterior through a dedicated register in order to access the recorded logs.

Data storage:

• Flight data: hour, minute, sec, navigation data (positions, GPS status, speeds, accelerations, turn rates, angular positions and uncertainties), DGPS data (pos, speed, precision, satellites), flight data ADS (pressures, TAS, CAS, temperature), engine parameters (model modifications: rpm, EGT, CHT…), AAP mode / status / substate, Fuel, lateral and vertical errors in takeoff and landing maneuvers, AAP temperature, PWMs, instantaneous weight…
• Electrical power management system data (V, I, T of the different lines).
• FCS inputs and outputs.
