The EDM900 Primary system allows you to replace your old steam gauge instruments with the most advanced and precise piston engine monitoring instrument on the market. Designed for both vertical and horizontal use, its offset rear processor offers nearly unlimited installation possibilities, while providing a long list of customizable options. TSO certified as a PRIMARY instrument and for its quality, the EDM 900 is not just another black box. It’s a flight engineer, a maintenance manager, and a backup instrument. At this price, nothing comes close. You can almost consider the EDM 900 as your personal flight engineer. It’s always there, working in the background, constantly monitoring your engine while you focus on flying the aircraft. You can complete an entire flight without ever pressing a button, if you wish. However, your EDM will monitor your engine parameters three times per second and will instantly alert you if any parameter exceeds the programmed limit.
Not only is the EDM 900 TSO certified (it is also available in a non-TSO version for experimental aircraft), but all the functions covered by the EDM 900 are TSO and STC certified as PRIMARY functions.
