Testing datalink in just a few clicks.

POCKET is the solution for no-fuss datalink testing

Now airlines can test data link easily, quickly, and securely. POCKET emulates ground data link communications systems, in order to test airborne systems independently of operational ground networks. It interacts with your aircraft’s datalink avionics system by exchanging test messages via a non-operational VHF frequency.

POCKET tests every part of the datalink system on-board your aircraft, from the VHF data radio to the communications router to the display system and ATC or AOC applications.

How do you benefit from POCKET?

  • Verify whether datalink is working in just a few clicks

  • Test datalink from inside the maintenance hangar and within the cockpit

  • Simplify test process: 1-person maintenance operation

  • Reduce the number of pilot reports generated

  • Eliminate need to connect to operational VHF networks

  • Verify your ATSU/CMU or VDR firmware update

  • Text Hover
