Working alongside the EDM 790 are the all new linearized thermocouples.

The CHT adapter probe is used in conjunction with the OEM CHT probe. The CHT adapter probe is a threaded probe that fits into the cylinder head thermo well and is available as a bayonet type or threaded type.

The aircraft engine performance can be analysed in detail provided there is some way for the engine data to be stored and later retrieved.

Start with ensuring that the RPM sensor is fitted to the correct vent plug of the slick magneto.

CHT Bayonet probes come in two flavours; non-grounded and grounded.

CHT Bayonet probes come in two flavours; non-grounded and grounded.

The temperature of the oil effects it’s viscosity and therefore flow rate and usefulness in lubricating the engine.

This article helps you compare the two EDM’s and select the one that fits your requirements and your budget. Both these aircraft engine data monitoring systems are manufactured by J.P. Instruments.

The all new full colour EDM 830 also includes user programmable gauges so the pilot can decide which Slim Line Gauges he would like to have displayed and the order of the display.

The EDM 900 has a long list of function - only a handful are covered here.

For accurate temperature data, ensure that the tip of the probe is in the centre of the exhaust stream. When sure that the IAT Probe is in the right place, tighten the stainless-steel clamp to a torque of 45 in/Lbs.

The JPI manufactured Fuel Scan 450 Twin uses two very reliable fuel flow sensors. Each of these sensors is mounted in the fuel line prior to the fuel distributor or carburettor and, they measure the actual fuel flowing through.

The compressor creates a continuous stream of high-pressure air that enables the aircraft to climb quickly.

The EDM 950 monitors the aircraft engine parameters roughly 180 times a minute and will warn the pilot the moment any parameter exceeds the pre-programmed limit.

The EDM 730 is a fantastic piece of aviation technology that offers full-colour high-contrast graphics.

The analog temperature display are in the form of electronic bar graph i.e one vertical column per cylinder. For additional clarity, actual temperatures in digital numbers are displayed below each bar.

The best location therefore, is to place OAT probe under the aircraft wing but sufficiently outboard so as to avoid exhaust heat - the bottom of the fuselage would be an ideal location.

They constantly monitor the health of the aircraft engine and any red-line events are instantly brought to the pilot’s attention via audio-visual alarms.

Inside the fuel flow transducer, is a miniature neutrally buoyant rotor finely balanced on jewelled bearings.

Each slim line gauge has a red line LED so any reading that is over or under is instantly brought to my notice.

Internal Memory - Enough memory to record 600 hours of data (recorded every 6 seconds).

The dimming switch is placed at the top right side of the scanner. The bright or dimming option is selected via the same button with each press alternating between the two states.

The presence of the compressor means the aircraft engine does not have to rely on free-flowing air that gets less and less with altitude.

Using sophisticated analytical software, the technician can analyse the engine performance minutely and figure out if any part of the engine required tuning / repairs or replacement.

Always push wires from the cabin through the firewall to the engine side and try to use existing rubber grommets. When you've finished, use flame retardant silicone to fill up any gaps along the wire route.

K-type CHT probes have sensitivity over a wide temperature range and are the preferred type for use as EGT or TIT probes.

Seat the CHT probe on the spark plug and then bend the probe upwards so the wire will be facing upwards when you re-fix the sparkplug.

Every 4 and 6-cylinder aircraft has twenty-nine critical components that ideally require constant monitoring.

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.

The propellers are connected to the crankshaft which in turn rotates a rotor inside the magneto.

Packed with electronic chips, the aircraft engine monitoring system 350, analyses 24 different function of the aircraft engine.

The aircraft engine data manager 740 system for 4 and 6 cylinders covers just about everything that any pilot would want.

Current aircraft flying around in the skies have either the analog fuel flow instrument or have the new digital version.

Before you install the EDM 960, located your fuel quantity calibration records as the installation engineer might need to refer to it at time of installation of the EDM 960.

Aircraft instrument repairs are supposed to be handled by approved shop and done under controlled conditions.

It’s a little digital machine that starts work the moment the aircraft engines are fired up.

Smaller than the average cell phone, the EDM 350 requires just 3.25 square inches of space amongst your instrument panels.

The EDM 900 comes equipped with the Remote Annunciator Light ‘RAL’ that provides notification that an alarm is present.
