The EDM 960 not only reads the data sent to it by the sensors, it has the ability to compare that data with extreme values pre-entered into the system by the pilots and; in the event that any sensor reading of the aircraft engine does not confirm to the pre-entered values, it will trigger an audio-visual warning.

1. The engine data monitoring system (EDM) 960 – the one manufactured by J.P. Instruments is
available for all aircraft with 4, 6, 7, 8 or 9 cylinders engines. There are so many things in an
aircraft that need to be monitored that in days gone by, there used to be a flight engineer
whose job it was to keep an eye on the engine performance during flight.
But the flight engineer was only human and during long flights, it was easy to not notice some
things. But being a machine albeit an intelligent one; the EDM 960 system electronically
surveys everything it is connected to, and it does it four times a second. Nothing can escape its
attention.
Some of the characteristics of the EDM 960 System:
The EDM 960 not only reads the data sent to it by the
sensors, it has the ability to compare that data with
extreme values pre-entered into the system by the
pilots and; in the event that any sensor reading of the
aircraft engine does not confirm to the pre-entered
values, it will trigger an audio-visual warning.
Apart from this, if you plug the appropriate GPS, it
can calculate time-to-empty in real time based on
actual fuel in the tank. It can compute distance,
calculate fuel requirement (based on current fuel use
rate), compare fuel requirement with available fuel
and display data on whether you can make it to a
way-point or not.
The EDM 960 System acts like your very own flight engineer – one that never feels drowsy or
sleeps during a flight.

2. Specifications of the EDM 960 Twin System manufactured by J.P. Instruments:
1. Lean Find™ finds the first and last
cylinder to peak with true peak
detect eliminates false peaks
2. Hands-free, automatic scanning
3. Displays both leaned temperature
below peak and peak
4. All programming done from the
Front Panel
5. Battery voltage with alarm
6. Programmable alarm limits
7. Amperes (load or charge/discharge
meter)
8. Normalize view
9. DIF low to high EGT with alarm
10. Exhaust Gas Temperatures (EGTs)
to stable 1°F resolution
11. EGTs to stable 1°F resolution
12. User selectable index rate
13. Shock cooling monitored on every
cylinder
14. Fast response probes
15. Records and stores data up to 30
hours
16. Non-volatile long-term memory
17. Post-flight data retrieval
18. Data retrieval software
19. Download to Palm™ Computer
20. Fuel level display
21. Oil pressure
22. Outside air temperature
23. Oil temperature
24. Adjustable display
25. Adjustable order of display
Other characteristics of the EDM 960 System include:
Display via liquid crystal display (LCD) screen as well as remote auxiliary display (RAD) (if
connected).
The default displays of the EDM 960 System include fuel pressure, oil pressure, oil
temperature, bus voltage amps, fuel flow (left and right separately), and outside air
temperature.
Without doubt, the EDM 960 is an invaluable safety device for the pilot and his aircraft. It
helps diagnose engine malfunctions, adjust air-to-fuel mixture, provide real time feedback on
the critical components of the Aircraft Engine Monitor as well as diagnose air craft

3. position vis-a-viz destination and compare it to fuel status (provided you have the right GPS
installed).
