ECL - OPERATION (CONT'D)
While the engine is operating in AUTO mode and the ECL is in FLIGHT
position, NG is adjusted by the EEC as a function of the power demand.
When the engine is switched to MANUAL mode, either because of EEC
failure or by pilot selection through the ENG GOV switch and the engine is in
steady state (NG = constant), no change in fuel flow is experienced.
The full range of NG values can then be achieved by moving the ECL:
• between MIN and FLIGHT if engine was operating at maximum power,
or
• between FLIGHT and MAX if engine was operating at minimum power,
or
• any intermediate range for any other initial power setting.
The amount of travel required for a certain amount of power change is the
same in the complete range of ECL travel.
