Max cont power = 92% at 2100RPM

29
Q

The lubrication system

A

2 independent systems for the engine and the gearbox

Wet sump with an external filter and cooler

30
Q

Engine and gearbox oil capacities

A

Engine = 7 litres (5 is min)

Gearbox = 2.1 litres - only serviceable by a mechanic

Some oil loss is normal (.1 lit/hr)

31
Q

Gearbox oil system also operates

A

The variable pitch prop

32
Q

SHELL SPIRAX S6 GXME 75W-80

33
Q

Engine oil

A

Shell helix ultra

5W30/40

34
Q

Fuel is delivered to a common rail via

A

LP and HP fuel pumps

Regulator/pressure relief valve controls the pressure

Rail supplies HP fuel to the injectors

35
Q

Injectors are controlled by

A

ECU

Excess fuel is returned via a fuel cooler

36
Q

The turbocharger uses

A

Filtered RAM air

In case of engine trouble, alternate air can be selected by pulling the alternate air lever - drawing air from inside the cowling

37
Q

ECU FAIL CAUTION could be caused by

A

Sensor failures

Insufficient performance of air,fuel or electrical supply system e.g air filter icing

38
Q

ECUs control

A

Injectors
CSU
Rail pressure
Waste gate

40
Q

Which fuel tank is main and which is auxiliary

A 
Main = right 
Aux = left

Aluminium tanks in each wing

Fuel must be drawn from the aux tank to be used in the main tank

41
Q

How many fuel pumps

A

2 parallel electrical LP fuel pumps
1 pump working at a time, when 1 fails then they switch

When the ECU switches from A to B then the fuel pumps also switch

42
Q

4 sections of the electrical system

A

Power generation
Storage
Distribution
Consumers

43
Q

Power generation

A
