Comparing EDM 760 and EDM 790 System

Press release   •   Aug 26, 2019 00:00 EDT

Comparing EDM 760 and EDM  790 SystemEDM 760 and EDM 790 are near identical EDM’s. The major difference being that EDM 790 is equipped with a full colour TFT screen. Both Engine Data Monitors are manufactured by J.P.I - World leader in Aircraft Engine Data Management systems.

EDM 760 and EDM 790 provide the pilots with real time information on the status and health of the aircraft engine. They constantly monitor the health of the aircraft engine and any red-line events are instantly brought to the pilot’s attention via audio-visual alarms. This leaves the pilots to concentrate on the flight experience rather than constantly monitoring gauges.
