Looking for an engine data management system that offers precision diagnostics, superior features, monitors 29 different critical engine parameters? Look no further than the EDM 790 system. The EDM 790 manufactured by JPI, USA, is perhaps the best aftermarket EDM and is worth every penny you spend on it. Moreover, though under US ten thousand dollars, this 4 / 6-cylinder EDM includes the transducers in its price and kit. An EDM is not something you change every year or even every other year, therefore; when planning to upgrade, you as the owner of your aircraft, will naturally want the most advanced, safest and best EDM that money can buy. Doesn’t matter how you analyse it, the EDM 790 system is truly the most advanced twin piston engine-monitoring instrument in the market. The Engine Monitors has been certified for quality and is as good as having onboard a Flight Engineer and Maintenance Manager. Here’s why the EDM 790 is so good: Every 4 and 6-cylinder aircraft has twenty-nine critical components that ideally require constant monitoring. The EDM 790 does just that – it monitors each of these components (provided they are connected to the EDM), using state-of-the-art high precision sensors (also manufactured by JPI). Armed with the latest microprocessor technology and quick response high precision sensors, the EDM 790 will critically analyse incoming data and compare it with pre-fed high and how values. Any sensor data that is not within the pre-set limits gets flagged and pilot(s) alerted. In fact, each of these critical components is monitored 4 times a second! Moreover, the EDM 790 is paired with linearized thermocouple with accuracy of better than 0.1 percent or 2 F°. This feat in high precision has been tested and certified and certified by the FAA. EDM 790 – always alert From the moment the aircraft engines are fired up, to switch off, the EDM 790 remains constantly alert monitoring all 29 critical parts of the aircraft engine - four times every second. In fact, even if the pilots have changed the display page and are looking at something else, the engine monitoring does not stop – it continues in the background. Precision The EDM 790’s precision is a combination of its linearized thermocouples, fast response sensors and state-of-the-art microprocessor circuits. No competitor product comes even close the matching the precision of EDM’s manufactured by JPI. Easy to operate The EDM 790 has two buttons located on the front and these two buttons are all it takes to programme the EDM and to use all its functions. Even ‘Leaning’ is done automatically with the LeanFind™ procedure. With the EDM 790 onboard, the aircraft maintenance engineer or technician now has substantially more diagnostic information available that can be downloaded via the data port.

The EDM 700 series engine data management system is one of the finest engine monitoring instruments available for the aircraft. In this article, will provide you with an overview and the special features of the engine data management 700 system. To begin with, the EDM 700 is analogues to a flight engineer always present in your cockpit and working silently in the background constantly watching over your engine while the pilots concentrate on flying the aircraft. Overview & Special Features of the EDM 700 System The EDM 700 Single Engine Monitor critical components of the aircraft engine three times a second and will warn the pilots instantly if any parameter is below or above the expected norm. The EDM 700 collects data and displays it for the pilots in a useful way. The EDM 700 is used to monitor engine temperatures and voltages, adjust the fuel air mixture and diagnose engine malfunctions. In the centre of the display screen, is the exhaust gas temperature (EGT bars) with the cylinder head numbers displayed on the top of each bar. The height of each column represents the EGT. The pilots can either see the display in ‘redline’ view or ‘normal’ view. The former is a percentage view of the EGT. In the normalized view the pilots can see even small subtle changes in the temperature – this enables the pilots to monitor the EGT very closely. In the normalized view, to begin with, all bars are equal height but; if there is any increase of decrease in temperature, the column height will instantly change. Each tick on the bar represents a 10-degree change. Actual EGT and CHT figures are displayed below the bar graph. This unit also displays the rate of shock cooling of the most rapidly cooling cylinder in degrees (ideal value should be below 50 degrees) per minute. Other displays include the bus voltage, the difference between the hottest and coolest exhaust gas temperatures. If you have the following optional features installed then, these too will be displayed: 1. The outside air temperature 2. Oil temperature 3. Fuel flow There are two buttons on the front panel. These control all functions of the EDM 700 on the left side is the step button and on the right side is a lean find button. Roughly 10 minutes after the EDM 700 is turned on it will automatically index through all parameters. Pressing this step button will turn this into a manual indexing mode and the pilot can observe each parameter value for as long the pilot wants. To resume automatic indexing, the pilots just needs to tap the lean find and then tap step to switch between the percentage view and the normalized view.

Today, let’s examine this little device that could make or break your day in the sky.
The Engine Analyzer / System Monitor 350 is a nifty little power-packed device which, when connected to the sensors, reads and analysis engine data. It effectively is a secondary pair of ‘eyes and ears’ for your aircraft – one that keeps constant watch over the engine. Occupying just 3.25-square inches of space in the aircraft’s dashboard, the aircraft engine monitoring system 350 manufactured by J.P Instruments, USA, is very easily fitted. Packed with electronic chips, the aircraft engine monitoring system 350, analyses 24 different function of the aircraft engine. Starting at just $798 for the basic 4-cylinder EDM 350 kit, this is one device that represents enormous value for money. J.P. I also have the 6-cylinder EDM 350 version that retails at $998. If the probes are already in place, fitting the EDM 50 can be done in as little as 30 minutes. Simply create a 3.25-inch space in your aircraft dashboard, thread all the probes through the newly created empty space and attach them to the 350 unit. Next, ‘plug-in’ the EDM 350 Aircraft engine data manager into that 3.25-inch space, secure the screws and you’re done. Information is power - the working of the EDM 350: Think of the Engine Analyzer / System Monitor 350 as a little onboard computer. It has prefed upper, lower and normal parameters for 24 different parts of your 4 or 6-cylinder aircraft engine. When the aircraft engine is powered on, the 24 sensors begin feeding data into the EDM 350. As the data flows in, two things happen; one- the EDM 350 displays the information in a neat and intuitive manner. Depending on the pilot selection, the data may be displayed as actual numbers or as graphs. Secondly, the data is constantly compared with the pre-fed high and low values for each data stream. Any parameters that does not fall in the ‘normal’ range, is flagged and an audio-visual alarm is triggered. The high and low values can be manually entered by the pilot. The 24 engine parameters that the EDM 350 watches over are: 1. EGT - Exhaust gas temp. 2. CHT - Cylinder head temp - probes and harness included. 3. CLD - Shock cooling on all cylinders. 4. VDC - Voltage display. 5. Internal Memory - Enough memory to record 600 hours of data (recorded every 6 seconds). 6. USB Port - Convenient data port for quick and easy download of engine data. 7. ROP/LOP - Lean finder. 8. MAP - Engine Manifold pressure. 9. DIFF - Engine health. 10. EZTrends Software - Graphics software with Google Earth location included. 11. O.T. - Engine oil temp. 12. RPM - Prop rotation speed. 13. F.P. - Fuel pressure. 14. OAT - Outside air temp. 15. O.P. - Engine oil pressure. 16. CRB - Carburettor temp. 17. CDT - Compressor discharge temp. 18. TIT - Turbine inlet temp. 19. L-R-Main - Fuel quantity in all tanks. 20. V-2 - Second volts readout. 21. AMP - Battery load output in amps. 22. % HP - With FF, OAT and RPM Sensor. 23. Amp-2 - Second load readout in Amps. 24. FF - Fuel flow includes: • GPH - Gallons per hour. • H:M - Endurance in hours and minutes. • REQ - Fuel required to way point / destination. • MPG - Miles per gallon • USD - Fuel used.
