Main parameters for archiving:

• Load on wings
• Load of several body frame points
• Load on landing gears (during take-off and landing)
• Engine management data
• On-board video recording of flight maneuvers and pilot activity in high loaded situations
• 3 axis acceleration measurement
• GPS position, absolute speed, altitude and date-time registration
• Aircraft air relative speed

Sampling rate of analog parameters are 1-10 samples/second

Sampling rate of video capture is 10-30 frames/second

The Data Archiving Box can store flight data during the whole lifetime of the airplane
