The fuel tank cross feed function is used for:

Transferring fuel from one tank to the other

Feeding an engine from the opposite tank

Balance fuel quantity in the tanks after uneven pressure refueling.

If start locks are not engaged during the engine shut down procedure, the propeller will:

Remain in fine pitch

Move towards feather

Continue to rotate for longer

If start locks are not engaged during the engine shut down procedure, the crew can:

Manually move the blades to feather

Use the unfeather pump to put propeller onto the start locks

Start up the engine in feather and follow the correct shut down procedure

Sticky start locks can be disengaged when the engine is running by:

Lubricating them during engine run

Inserting a piece of locking wire to hold them out

Increasing engine RPM using the speed lever and trying again

A vibrating propeller must be balanced in order to prevent:

Discomfort for the passengers due to excessive noise and vibration

Damage to sensitive instruments in the cockpit, especially gyros

Damage to internal gearbox gears and bearings leading to SOAP alerts

The function of the feather valve is to:

Feather the engine during start

Block oil pressure from leaving the propeller dome back to the oil tank

An auto start uses which components to control FF and IGN:

The fuel shutoff valves

The pressurizing valves

The speed switches

As oil temperature increases, its effect on oil pressure is as follows:

No effect as the oil pressure regulator compensates the output

Pressure rises

Pressure falls due to lower viscosity of hot oil

A rise in oil temperature together with a drop in oil pressure is a sign that:

Nothing is wrong, the engine is operating normally within its parameters

There is low oil quantity in the tanks and it must be filled at the next stop

There could be an internal engine problem heating the oil causing a pressure drop due to lower viscosity.

An oil temperature system gauge error can be checked:

On ground before start with cold engines

In flight with cold engines on the first flight of the day

By using a digital multi meter to check that the system voltage is balanced

A sudden higher-than-normal engine oil temperature during flight, when all other parameters remain the same, is most likely due to the following:

All the oil has leaked out of the oil cooler

The indicator needle is stuck in the high oil temperature position

High system resistance has introduced an oil temperature gauge error

Immediate ITT, RPM, FF drop after activating the STOP switch

Immediate ITT, RPM, FF rise after activating the STOP switch

ITT, RPM rise and FF drop after activating the STOP switch, and an audible change in the engine sound.

The correct functioning of the engine fuel purge system is important because:

It burns excess fuel in the nozzles to prevent clogging

It prepares the engine for the next auto start sequence

It purges the excess fuel from the nozzles back to the fuel tank

The correct procedure to extinguish an engine tail pipe fire is:

Shut down the affected engine and immediately depress the engine START switch to blow out the fire.

Empty

Full

Same level as the main tank

If both boost pumps fail during flight, the following statement is true:

There is a danger of the engine shutting down; land as soon as practical

With 1,200lbs total fuel showing on the gauges, and the “LH FUEL QTY” light illuminates, crew should:

Ignore the warning, as it must be a false reading as the fuel gauges show sufficient fuel

Transfer fuel from the opposite fuel tank until the low level light goes off

Failing fuel quantity probes can:

Cause the fuel gauges to over read the fuel quantity

Cause the fuel gauges to get stuck and not move

If both boost pumps on one side have failed during flight, what will happen to the engine?

If the engine torque indication suddenly reads 20% lower, but the FF, ITT and RPM indications remain the same:

The torque indication system is not accurate due to a single gauge being affected

The engine has lost 20% torque, therefore crew should advance the power lever to compensate

The engine is experiencing an actual loss of power as the torque gauge is showing lower torque.

If the engine torque indication is suddenly 20% lower with a corresponding reduction in FF and ITT:

The torque indicating system is not accurate due to multiple gauges being affected

The engine is experiencing an actual reduction of power due to multiple gauges confirming a change in power output

Adjust torque as necessary using the engine power lever

Before any engine start, crew must first turn the propellers by hand to check:

That the engine not binding before engaging the starter

That the engine is cool enough for starting
