ARINC 717
ARINC 717 is a standard that defines the data format of digital flight data recorders, issued by the company Aeronautical Radio, Incorporated (ARINC).[1] It specifies the communication between various avionics systems and sensors and the flight data recorder.[2] It replaces the older ARINC 573 standard, which was based on analog inputs. It allows for more data and real-time recording.[3]
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.[4]
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
