Q

On a Left-Zero Ammeter, if the Ammeter drops to Zero, what does this indicates?

A

The Alternator is not working.

23
Q

How can a Pilot double-check the Alternator has failed, through the Left-Zero Ammeter instrument?

A

By add more power usage to see if the instrument reading reflect this.

24
Q

What is a Circuit Breaker?

A

An automatic device stopping the flow of Current in the interest of Safety.

25
Q

If a Circuit Breaker pops for the 2nd time, what should a Pilot do?

A

Report this as the Electrical System may have a bigger problem.

26
Q

How are Brakes powered in a light training Aircraft?

A

Use of Hydraulic-fluid.

27
Q

How does the Parking Brake work?

A

By locking the Hydraulic-fluid in place.

28
Q

What signs of impending failure of the Brakes can a Pilot detect (3)?

A
  • Soft Pedals.
  • Weak Braking Action.
  • Noisy Brakes.
29
Q

If a Brake Disc fails, how can a Pilot slow the plane down (2)?

A
  • Using the other Brakes.

- Use of opposite Rudder.

30
Q

What is the purpose of the Vacuum System?

A

To provide power source to Gyroscopic Instruments.

31
Q

Name four parts to the Vacuum System?

A
  • Vacuum Pump.
  • Vacuum Suction Relief Valve.
  • Vacuum System Filter.
  • Suction Gauge.
32
Q

What mechanical item provides the Vacuum System power?

A

Engine-driven Suction/Vacuum Pump.

33
Q

Name two types of Engine-driven Suction/Vacuum Pumps?

A
  • Dry Pump.

- Wet Pump.

34
Q

What does a Vacuum Suction Relief Valve do?

A

Reduces excessive Suction.

35
Q

What is the Suction Gauge?

A

Cockpit Instrument which indicates if enough Suction is being provided to power certain Flight Instruments.

36
Q

If the Suction Gauge has a reading of Zero, what does this show?

A

Vacuum Pump Failure.

37
Q

How can a Pilot detect if the Suction Gauge is faulty, rather than the Vacuum System?

A

By looking at the Attitude and/or Directional Indicator and check if the reading is the same as the flight.

38
Q

How can a Pilot check the difference between a faulty Suction Gauge and a complete failure to the Vacuum System?

A

By Banking the Aircraft to check if Attitude and/or Directional Indicator provides the correct reading.

39
Q

True or False. Under Visual Flight Rules, is it possible to continue flying an Aircraft without the Vacuum System and all Gyroscopic Flight Instruments being faulty? If so how?

A

True. By using reference with the horizon and magnetic compass.

40
Q

What happens to the Gyroscopic Instruments if the Vacuum System has built up of Dirt?

A

Unreliable Readings.

41
Q

The Pitot-Static System provides readings for which Flight Instruments (3)?

A
  • Altimeter.
  • Airspeed Indicator (ASI).
  • Vertical Speed Indicator (VSI).
42
Q

Which Flight Instrument using Dynamic Pressure to obtain it’s reading?

A

Airspeed Indicator.

43
Q

Which Flight Instruments using Static Pressure to obtain it’s reading (2)?

A
  • Altimeter.

- Vertical Speed Indicator (VSI).

44
Q

Which Flight Instrument uses both Pitot and Static Pressure?

A

Airspeed Indicator (ASI).

45
Q

What is Total Pressure?

A

Sum of Static and Dynamic Pressure.

46
Q

Total Pressure is also known as what?

A

Pitot Pressure.

47
Q

The Pitot Tube sense what kind of Pressure?

A

Total/Pitot Pressure.

48
Q

The Static Vents sense what kind of Pressure?

A

Static Pressure.

49
Q

Name three common blockage of the Pitot Tube?

A
  • Pitot Tube cover.
  • Dirt.
  • Ice.
50
Q

True or False. If the Pitot Tube were to be blocked, the Airspeed Indicator, Vertical Speed Indicator and Altimeter would be affected?

A

False. Only the Airspeed Indicator will be affected.

51
Q

True or False. If the Static Vents were to be blocked, the Airspeed Indicator, Vertical Speed Indicator and Altimeter would be affected?

A

True. As Static Pressure provides readings for all three Flight Instruments.

52
Q

If Static Pressure is blocked, what can the Pilot use to regain some pressure readings and where is this located (2)?

A
  • Alternative Static Source.

- In the Cockpit.

53
Q

If a Pitot Tube is blocked by Ice, what can a Pilot do to counter-act this?

A

Apply Pitot Tube Heater.

54
Q

When is a Pitot Tube vulnerable to Icing?

A

With temperatures at or below 0°C and with visible moisture in the air.
