EDM 790 is truly a top-of-the-line Aircraft engine data manager. It is without doubt, the best EDM system that money can buy and provides the best return for your money. With a price tag a tad under ten grand, the EDM 790 is designed for 4 and 6-cylinder aircraft engines and accessories include the transducers. Billed as the most advanced twin piston engine-monitoring device in the market, is not the only feather in its cap; the EDM 790 has been TSO’d for quality and is as good as having a Flight Engineer and Maintenance engineer onboard; one who never nods off or losses concentration during a flight – not even for a second. The EDM 790 watches over 29 critical parameters: The EDM 790 is designed to watch over 29 critical parameters of the aircraft engine and to sample the data 4 times a second. Nothing even comes close to being as good. Moreover, the FAA has tested the EDM 790 and confirms that the device has a linearized thermocouple accuracy of 0.1 percent or 2 F°. When the testing agency certifies as to the awesomeness of the EDM 790, need we look further? The EDM 790 never loses concentration: It’s a little digital machine that starts work the moment the aircraft engines are fired up. The EDM 790 picks up data for 29 critical parameters, displays the readout on the screen and at the same time, looks for anomalies by comparing the figures with pre-stored data. Any variance is instantly brought to the notice of the pilots by displaying the digits in bright red colour and also flashing a hard-to-miss warning light. Linearized thermocouple accuracy: Search as much as you like but you would be hard-pressed to find another instrument that will match the EDM 790 for accuracy. Two- button simplicity: The EDM 790 faceplate sports two buttons and that is all it takes to programme it. No complicated pre-set required. Also, the pilot can accomplish leaning easily and automatically using the LeanFind™ procedure. Additionally, the JPI EDM 790 offers substantially more diagnostic information for the crew. Here are a few advantages of the EDM 790: 1. Easy-to-use, easy-to-learn 2-button programming. 2. Artificial Intelligence assisted diagnostics. If any errors are detected, the specific code is displayed along with blinking warning LED. 3. Alphanumeric scanning display of 29 functions or channels. 4. Keeps a watchful eye on 29 engine parameters including the Alternator Voltage, EGT Differential, Fuel Flow and Shock Cooling. 5. EGT Bar Graphs are displayed as variable scales. 6. It’s amazing PeakFind™ and the paired probes, automatically captures the EGT Probe or TIT peak value. Also, the LeanFind™ Mode identifies the first and last cylinder to peak. 7. Downloading engine data is easily accomplished with the Data Port. 8. Cooling rate and shock cooling checked on each and every cylinder. 9. The EDM 790 with fuel flow monitor is the only such device to receive FAA approval. 10. Awesome temperature captures accuracy of ONE degree (even for EGT). 11. Comes paired with ‘grounded’ fast response Probes & Sensors. 12. TSO Certificate for reliability and quality. Also, STC and FAA approved for accurate Fuel Flow data. 13. Three-year warranty.

The compact Engine Data Manager 350 manufactured by California based, J.P. Instruments is a small foot-print digital device that keeps track of several key functions of your aircraft engine. Smaller than the average cell phone, the EDM 350 requires just 3.25 square inches of space amongst your instrument panels. Despite its size, the EDM 350 engine data manager, is a powerful little gadget that is armed with the ability to analyse data from 24 different streams. It’s your extra pair of eyes that keeps watch over the engine while you enjoy the flying. The EDM 350 is suited for any 4 or 6 -cylinder aircraft with the basic kits (for the 4-cylinder aircraft) starting at just $798 and the 6-cylinder one priced at $988. An extra paid of intelligent eyes for under $1,000 is definitely a bargain. Any aircraft maintenance technician will tell you that fitting the EDM 350 in the 4 or 6-cylinder aircraft is a piece of cake! All you need to do is, first attach the probes and next attach them and the wires to the EDM 350 instrument. Finally, ‘plug-in’ the instrument into the 3.5-square inch space provided for it and you’re done. What could be easier? Now let’s see how the EDM 350 works: The EDM 350 is packed with powerful electronics that can do complex comparisons in nanoseconds and decide whether a particular set of figures is ‘high‘, ‘low’ or ‘normal’. It does this for 24 different engine parameters and all at the same time. No human can match this ability. When the pilot switches on the aircraft engine, 24 highly sensitive sensors attached to different parts of the aircraft engine, begin transmitting data to the waiting EDM 350 which in turn interprets the data, displays it on the LCD screen and also intelligently decides whether everything is normal or whether there is a problem. Abnormal figures are displayed in red. The EDM 350 keeps watch over these engine parameters: 1. EGT - Exhaust gas temp. 2. Cylinder head temp. 3. ROP/LOP - Lean finder. 4. VDC - Voltage display. 5. DIFF - Engine health. 6. CLD - Shock cooling on all cylinders. 7. Convenient USB data port for data download. 8. Memory for recording 600 hours of data. 9. Custom software that includes Google Earth location. 10. RPM - Prop rotation speed. 11. MAP - Engine Manifold pressure. 12. F.P. - Fuel pressure. 13. O.T. - Engine oil temp. 14. OAT - Outside air temp. 15. O.P. - Engine oil pressure. 16. TIT Probe - Turbine inlet temp. 17. CRB Probes - Carburettor temp. 18. L-R-Main - Fuel quantity in all tanks. 19. CDT - Compressor discharge temp. 20. V-2 - Second volts readout. 21. AMP - Battery load output in amps. 22. Amp-2 - Second load readout in Amps. 23. Percentage HP - With FF, OAT and RPM. 24. FF - Fuel flow includes: • REQ - Fuel required to way point / destination. • GPH - Gallons per hour. • H:M - Endurance in hours and minutes. • USD - Fuel used. • MPG - Miles per gallon For more information on EDM 350 Aircraft Engine Data Management by J.P.
