The Engine Data Management 930 system is the most advanced and accurate piston engine-monitoring instrument on the market. TSO'd as a PRIMARY instrument and for quality, the EDM 930 is not just another black box along for the ride. It is a Flight Engineer ... a Maintenance Manager ... a Backup Instrument. For the price there is nothing that gets close to it. You can almost think of the EDM 930 as your personal flight engineer. It's always there, working in the background, constantly watching over your engine while you concentrate on flying the aircraft. You can make an entire flight without ever pushing a button, if you so choose. Yet your EDM will be monitoring your engine parameters three times a second and will warn you instantly if any parameter exceeds the programmed limit.
