ARINC 717

ARINC 717 defines a digital flight data recorder, with its inputs and outputs. It replaces the older ARINC 573 characteristic, which was based on analog inputs. It allows for more data and real-time recording.^[1]

Digital Expandable Flight Data Acquisition and Recording System (DEFDARS) flight recorder output signals include the following:

Primary Output – ARINC 717 Harvard biphase encoding
Auxiliary Output – ARINC 429 (DITS) bi-polar encoding

ARINC 747 defines an alternate solid state recorder that can be used with an ARINC 717 installation.^[2]

DEFDARS includes the following component functions

Digital Flight Acquisition Unit (DFAU)
Digital Flight Data Recorder (DFDR)
Accelerometer
Flight Data Entry Panel (optional) for entry of flight data
