Draft 3 of Project Paper 834A: Internet Protocol based Aircraft Data Interface Function (ADIF)

The ARINC Industry Activities (IA) staff prepared this draft based on recommendations from the Electronic Flight Bag (EFB) Subcommittee meeting held November 3-5, 2020 and subsequent online meetings.
This project was initiated in response to APIM 17-014. The attached document is intended to define a new Application Programming Interface (API) between crew device applications executing on an EFB (for direct use by flight, cabin, and maintenance crew) and the aircraft avionics systems. This new interface is expected to become a bridge between EFB applications and the existing Simple Text Avionics Protocol (STAP), and Avionics Data Broadcast Protocol (ADBP) that acquire data from the aircraft data buses. The benefits of this standard are expected to include:

  • Improved application interoperability and product availability from multiple suppliers
  • Reduced development time and software maintenance overhead
