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

The EDM 900 alarm consists of three parts; the digital readout changes colour to yellow or red (depending upon intensity of the problem), secondly, the message area will display the error code and finally, just so the pilot does not miss it, RAL light will blink to gain pilot attention.

After a refuel, the pilot manually enters the quantum of fuel filled into the tanks. From there on, the digital fuel flow instrument takes over.

The fuel flow transducer works upon a vane RPM Sensor that is usually located behind the fuel filter and works in combination with the manifold air pressure (MAP).
