21
Q

Excessively high Cylinder Head Temperatures at high Engine Power Settings can be caused by an (over-lean/over-rich) mixture?

A

Over-lean.

22
Q

At Engine Power Settings above 70-75% maximum continuous in Aircrafts with a fixed-pitch propeller, what position should the mixture control be in?

A

Full Rich.

23
Q

Vapour locks during ground operations on hot days are more likely with (Carburettor/Fuel Injection) systems?

A

Fuel Injection.

24
Q

Why is it not recommended to run a Fuel Tank dry before switching tanks?

A

Because the Fuel flow may be stopped.

25
Q

Why should the Carburettor Heat Control be selected to OFF after landing?

A

To avoid dust ingestion.

26
Q

Inadequate lubrication is indicated by a (high/low) Oil Pressure and/or a (high/low) Oil Temperature?

A
  • Low.

- High.

27
Q

If a left-zero Ammeter indicates zero, this is likely to indicate (Flat Battery/Alternator Failure)?

A

Alternator Failure.

28
Q

If an Alternator fails in flight, what becomes the emergency electrical power source?

A

The Battery.

29
Q

Failure to an Alternator (or generator) with a (left-zero/centre-zero) Ammeter, will be indicated by a constant discharge on the Ammeter while electrical services are being used?

A

Centre-zero.

30
Q

Air Filter blockages in the Vacuum system, will be indicated by a (higher/lower) pressure on the suction gauge?

A

Lower.

31
Q

What is the likely effect of a blocked Static Vent on the Altimeter during a climb?

A

The Altimeter will remain unchanged.

32
Q

True or False. The ASI is the only pressure-operated flight instrument affected by a blocked Pitot-Tube?

A

True.

33
Q

IAS is a measure of (Dynamic/Static) pressure?

A

Dynamic.

34
Q

In case of blockage, an Alternate Static source is often provided. When used, this Alternate Static Pressure will normally be lower than it should be. What effects does this have on the Altimeter and the ASI?

A

Both instruments will over-read.

35
Q

What effect does a blocked Static Vent have on the VSI?

A

The VSI will read zero.

36
Q

If during descent the Static Vent becomes blocked with ice, what effect would this have on the Aircraft’s ASI?

A

The ASI will over-read.

37
Q

To ensure an accurate indication of magnetic direction, the heading indicator should be realigned with the magnetic compass (every 10-15 minutes/every 3 hours/before Takeoff)?

A

Every 10-15 minutes.

38
Q

What flight instrument is likely to be unserviceable if there are air bubbles in the liquid or the liquid is discoloured?

A

Magnetic Compass.

39
Q

What type of manoeuvres are likely to cause the gyros to topple and become temporarily unreadable or unreliable?

A

Steep turns and dives.

40
Q

If you apply Carburettor Heat to check for the presence of Carburettor Icing in an Aircraft with a fixed-pitch propeller, you will notice an initial (increase/decrease) followed by a gradual (increase/decrease) in Engine Speed?

A
  • Decrease.

- Increase.

41
Q

How do you check for correct operation of Carburettor Heat prior to Takeoff in an Aircraft with a fixed-pitch propeller?

A

During pre-Takeoff check, at 1600 RPM, a small drop in power will indicate correct operations.

42
Q

In case of impact ice blocking the air intake of a Fuel Injection System, (Carburettor Heat/Alternate Air) is available?

A

Alternate Air.

43
Q

Does the use of Carburettor Heat increase or decrease Engine Power Out in Aircraft’s fitted with fixed-pitch propellers?

A

Decrease.

44
Q

What effect does the application of Carburettor Heat have on the Fuel/Air Mixture?

A

It gets richer.

45
Q

On an Aircraft fitted with a fixed-pitch propeller and an EGT gauge, the manual mixture control is moved to either peak EGT or just on the rich side of peak in order to (lean/enrich) the mixture more efficiently?

A

Lean.

46
Q

During a climb, you notice a high reading on the Oil Temperature gauge. How could this high Oil Temperature be reduced (2)?

A
  • Reducing Power.

- Lowering the nose to increase Airspeed.

47
Q

Would increasing the Airspeed in a climb (increase/decrease) the Cylinder Head Temperature?

A

Decrease.

48
Q

Prolonged idling is likely to cause (Excessively Rich Mixtures/Fouled Spark Plugs)?

A

Fouled Spark Plugs.

49
Q

One way to reduce high Cylinder Head Temperature and avoid detonation is to (Lean the Mixture/Reduce Power)?

A

Reduce Power.

50
Q

A probable reason why an Engine continues to run after the ignition switch has been turned off is (Faulty Magneto Timing/A Disconnected or Broken Magneto Ground Wire)?

A

A Disconnected or Broken Magneto Ground Wire.
