Flight Data Evolution in General Aviation
Round Dial “Analog/Electrical” Cockpits
 Minimal amount of available flight data to acquire &
record
 Minimal mandatory requirements for crash survivable
flight data recording
Glass “Digital/Electronic” Cockpits
 Growing amount of available flight data to acquire &
record
• Digital avionics, buses, engine controls, etc.
 Relatively low cost avionics are rapidly emerging
Interest growing at Operators, OEM’s, FAA and Insurers
Flight Data Processing Considerations for GA
 Once available flight data is defined
 How often will it be sampled
 Amount of on-board processing, if any, before recording
 How will it be recorded?
 How will it be retrieved for analysis?
 How often will it be retrieved for analysis?
 Who will do the analysis?
 Traditionally, airlines manage their FDM programs
 GA OEM’s are becoming proactive (Embraer, Eclipse, Cirrus)
• Advantage is more statistical confidence when trending
• Data can be made accessible to relevant parties
 Depending on the desired information, operators will need to commit
more, or less, resources
Flight Data Retrieval Factors
 Quantity - More is better
 More types of data, more analysis capability
 Higher sampling rates, better analysis
 Accuracy - No garbage in, no garbage out
 Acquisition, recording, processing, analyzing
 Data retrieval timeliness - sooner the better
 Manual - human in the loop
• Data milking with laptops
• Pulling & replacing flash cards (EMax)
• Data gets lost, corrupted, and walks away
