23
Q

If the cowl flaps are stuck in the closed position during a climb, the Engine will most likely get too (hot/cold) and the Pilot will need to take action to (warm/cool) it?

A
  • Hot.

- Cool.

24
Q

Vapour locks in the fuel lines are more likely to occur at (high/low) atmospheric pressures and in (high/low) temperature conditions?

A
  • Low Pressures.

- High Temperatures.

25
Q

Are vapour locks in the fuel system at high Altitudes more likely in Aircraft with pump-fed or gravity-fed fuel systems?

A

Pump-fed.

26
Q

In pump-fed fuel systems, will the additional use of the boost pump at Altitude increase or decrease the risk of vapour locks due to low atmospheric pressures?

A

Decrease the risk.

27
Q

The grade of AVGAS, 100 LL, is coloured (blue/green) and AVTUR is coloured (blue/green/clear)?

A
  • Blue.

- Clear.

28
Q

The (higher/lower) the octane rating of fuel, the greater the stability of the fuel-air mixture?

A

Higher.

29
Q

Fuels with a (high/low) octane rating are more prone to detonation?

A

Low.

30
Q

Fuel of a higher grade than specified is likely to cause (detonation/spark plug fouling)?

A

Spark Plug Fouling.

31
Q

Could using the wrong type of oil, or mixing aviation oils with other types for use in an Aircraft piston Engine, damage the Engine?

A

Yes.

32
Q

What is the term used to describe an oil’s flow properties?

A

Viscosity.

33
Q

(High/Low) viscosity oils flow more freely?

A

Low.

34
Q

Oil is more sluggish in (cold/hot) weather?

A

Cold.

35
Q

(High/Low) temperatures decrease an oil’s viscosity, thus allowing it to flow more freely?

A

High.

36
Q

True or False. Different grades of single viscosity oil are used according to whether the temperature is hot or cold?

A

True.

37
Q

For what purpose are multi-grade oils produced?

A

The oil can be used in both hot and cold temperatures.

38
Q

42
Q

When is the oil level checked and how is this done (2)?

A
  • Preflight Inspection.

- Checking level on a dipstick.

43

47
Q

A fluctuating oil pressure accompanied by a high oil temperature is a likely indication of (the wrong type of oil/a low oil quantity)?

A

A low Oil quantity.

48
Q

Too low an Airspeed at high power settings is likely to lead to (high/low) cylinder head temperatures?

A

High.

49
Q

If an Aircraft is not fitted with a CHT gauge, how can the Pilot tell if the Engine is overheating? What is the likely consequence of Engine overheating (2)?

A
  • Very high Oil Temperature reading on gauge.

- Likely to lead to Engine Failure.

50
Q

What action can a Pilot take if the CHT or oil temperature gauges indicate that the Engine is overheating (4)?

A
  • Reduce Power.
  • Increase Airspeed.
  • Open Cowl Flaps.
51
Q

If the Engine bearings or oil pump failed, this would most likely show up as a loss of (oil temperature/oil pressure)?

Oil Pressure.

52
Q
