DA 42 NG AFM Airplane Description

7.9.3 OPERATING CONTROLS
Power Lever
Engine performance is controlled by a power lever for each engine. Both power levers
are situated on the large center console. ‘Front’ and ‘rear’ are defined in relation to the
direction of flight.
Each power lever is used to set the desired engine power LOAD (%)
Lever forward (MAX) = Full power
Lever to rear (IDLE) = Idle
A separate ECU for each engine controls manifold pressure, injected fuel quantity and
propeller speed according to the desired engine power preselected with the power lever.
If the power lever is in a low power position - as for a landing approach - while the landing
gear is retracted, an aural warning alerts the pilot to the retracted landing gear. Additionally,
a CHECK GEAR caution is indicated on the PFD.
A propeller governor, which is controlled by the ECU, is flanged onto the front of each
engine. The propeller governor oil circuit is supplied with oil by the gearbox oil pump (also
see Section 7.9.2 - PROPELLER). A loss of oil pressure leads to a feathering of the
propeller blades, thus allowing continuation of the flight according to 3.12.3 - DEFECTIVE
PROPELLER RPM REGULATING SYSTEM.
CAUTION
Following governor failure the RPM should be adjusted using
the power lever. Every effort should be made not to exceed
2300 RPM.
