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 ... Read more »

Data display on the EDM 900:

The Engine Data Management 900 (EDM 900) system’s display screen is arranged into three sections. The top left is the Engine Manifold Pressure (MAP) and Engine Rotation Speed (RPM) section. On the pilot’s right side are the horizontal primary strip gauges and at the bottom left is the Scanner® section or message area.

All the non-primary gauges have a digital read out only. The EDM 900 has pre-set alarms and range limits that are configured to match the aircraft it is being fitted into.

The EDM 900 comes equipped with the Remote Annunciator Light ‘RAL’ that provides notifica ... Read more »

There are analog dials, there are digital scanners and then there are classic scanners – each better than the previous. All these dials and scanners are used in modern aircraft to provide engine related information to the pilot(s).

Let’s say as a pilot flying an aircraft, you wanted to know the Exhaust Gas Temperature (EGT). You could do it the old-fashioned way by installing an analog dial EGT gauge or, you can do it the modern way by installing a digital scanner.

A typical scanner (depending on its sophistication), is paired with one or more sensors / probes e.g. EGT and CHT probes. Each of these sensors or probes in turn, is plugged into different parts of the aircraft engine. These sensors (or probes) send back data to t ... Read more »

If you have purchased or are thinking of purchasing the J.P.I. Engine Data Manager EDM 760 for your aircraft and want to know more about its features and operation, you’ve come to the right place.

To begin with, the 760 series engine data management is one of the finest engine monitoring instruments available for piston engine aircraft. The J.P.I. EDM 760 system for aircraft is as good as a personal flight engineer and once installed, will keep working in the background watching over the aircraft engine(s) while you concentrate and enjoy flying the aircraft.

The EDM 760 System and its advantage to your aircraft:

The EDM 760 connects to the aircraft engine via multiple sensors. These sensors pickup up the engine data and transmit it via ... Read more »

The EDM 790 manufactured by J.P. Instruments, U.S.A. is perhaps the best Engine Data Management system that money can buy for under US 10K for 4 or 6-cylinder aircraft engine – and this also includes the transducers.

If you are looking for the best deal for a twin piston engine-monitoring instrument in the market, look no further than the awesome EDM 790. It has been TSO’d for quality and is considered as the Flight Engineer and Maintenance Manager of your aircraft.

Covers all 29 critical parameters

Your twin engine aircraft has 29 critical parameters that ideally require constant monitoring – and you know how tough it can be. ... Read more »

For technicians about to install the JPI EDM 740 in an aircraft, this article is for you. It covers all the general points to installing the JPI EDM 740.

To start with, only FAA certified aircraft mechanic should attempt to install the EDM 740 in aircraft.

General Installation Instructions:

1.The EDM 740 (as do all EDM’s), are equipped with a delicate LCD display module. To prevent any damage to it, it is imperative that the mounting screws not penetrate the instrument by more than 0.12 inches. Ideally, use the steel template supplied with the installation kit.

2.The aircraft on which the EDM 740 is to be installed, should have necess ... Read more »

Combustion whether in aircraft or cars or anything that has an engine, not only relies on accurate mixture of air with fuel before ignition, it also requires the air and fuel to be at optimal temperature - this ensures instant and clean combustion.

Aircraft typically fly at altitudes where the air is very cold. This cold, dense and often freezing air impedes combustion and may even need to be pre-heated before mixing with fuel. So how does the aircraft know if the air is at the correct temperature or not? This is where the Intake Air Temperature (IAT) sensor comes into play.

An automobile engineer’s solution to the cold air problem would be to increase the fuel in the fue ... Read more »

Even the Wright brothers plane had a couple of dials near their seat in the plane. If nothing else, they at least had to know how much fuel they had in the fuel tanks.

Without the presence of a working dial or two, as a pilot, you wouldn’t have the foggiest idea on what was happening in the engine compartment – let alone know where they were going. Today, thanks to aircraft engine monitors, the pilot is often aware of a major life-threatening aircraft engine malfunction before it even happens.

Are the cylinders over-heating? Is there a fuel line block? Is the magneto malfunctioning causing the voltage to fluctuate or drop? And so on and so forth ... Read more »

Either you are planning to upgrade from an older EDM to EDM 730 or are planning on replacing some analog dials with the EDM 730 but in either case, your choice of EDM 730 could not have been better.

The Aircraft Engine Data Management 730 is an awesome piece of technology that offers clear, full-colour high-contrast graphics. It is easily installed (vertical or horizontal) and is considered as the most advanced and accurate piston engine-monitoring and advisory instrument on the market. It has been TSO’d for quality.

The Aircraft Engine Data Management 730 is one of the easiest to programme and all programming is done from the front panel.

Here is an ab ... Read more »

Here are the top 10 tips on installation of a Turbine Inlet Temperature (TIT) probe in your aircraft:

1. Before you even open the package containing the TIT probe, you need to do a little planning i.e. determine the exact location of hole for placing the TIT probe and while doing so, ensure that there is nothing nearby that would interfere with the probe, clamp, clamp screw or wire of the TIT probe.
2. Provide service loops at the instrument – you don’t want to run out of wire during maintenance at some future date.
3. Provide service loops at the engine end as well so that the probe can be swapped to adjacent cylinder positions for troubleshooting purposes.
4. Ensure a ... Read more »
