23
Q

True or False. Complete loss of Oil Pressure and a rapidly rising Oil Temperature indicates Engine Failure is imminent?

A

True.

24
Q

True or False. A Pilot should check the Propeller Blade for any damages before flight?

A

True.

25
Q

Preflight Check: Name 3 items to check before flying on Fuel?

A
  • Sufficient amount of Fuel for Flight.
  • Test for Fuel Contamination and correct grading.
  • Check Fuel Tank Vent for any blockage.
26
Q

Preflight Check: Name 3 items to check before flying on Oil?

A
  • Sufficient amount of Oil before Flight.
  • Check Oil is of correct type and grade.
  • Check Oil Pressure registers within 30 seconds of starting.
27
Q

Preflight Check: Why should a Pilot check the Propeller?

A

For any damages.

28
Q

Preflight Check: How should the Carburettor Heat Control be used prior to Takeoff (2)?

A
  • Turn ON to remove any build-up of Ice.

- Turn OFF before Takeoff.

29
Q

Preflight Check: What position should the Mixture Control be set as?

A

FULL RICH.

30
Q

Preflight Check: Why should a Pilot check each Magneto?

A

To see if the Spark Plugs are working normally.

31
Q

Inflight: Why should a Pilot monitor the Tachometer?

A

For any signs of power loss.

32
Q

Inflight: If the Tachometer is showing a gradual loss of power, what should a Pilot suspect and what course of action should be taken (2)?

A
  • Carburettor Icing.

- Turn the Carburettor Heat Control to FULL/ON.

33
Q

Q

Event of Engine Failure: If Power is not restored what should a Pilot prepare for?

A

A forced Landing with Power.

48
Q

Event of Engine Failure: How can a Pilot test the Magnetos during flight?

A

Turn switch to L then to R then back to BOTH.

49
Q

Event of Engine Failure: What should a Pilot do if operating on one Magneto?

A

Reduce Power.

50
Q

True or False. Fuel Pressure indication will be normal if complete power loss is due to water in the Fuel?

A

True.

51
Q

Name three element of an Engine Fire?

A
  • Fuel.
  • Oxygen.
  • Heat.
52
Q

Event of Engine Fire: How can a Pilot remove the Fuel being fed to the Engine (2)?

A
  • Turn OFF fuel from Shut-Off Valve.

- Selecting Mixture Control as IDLE CUT-OFF.

53
Q

Event of Engine Fire: How can a Pilot remove the oxygen being fed to the Engine?

A

By closing the Throttle.

54
Q

Event of Engine Fire: How can a Pilot remove the heat being fed to the Engine?
