40
Q

What is the reason for swinging the compass and how is it accomplished

A

Try compensate for deviations caused by the magnetic fields in the aircraft by adjusting the compensating magnets

41
Q

Why are transport category aircraft equipped with a master caution and warning system

A

To alert the crew that a malfunction has occurred and corrrective actions may be required

42
Q

How is a pilot alerted that an anti-skid system has automatically returned to a manual brake system?

A

By a warning light.

43
Q

What is the significance of an anti-skid warning?

A

The system is off or has failed.

44
Q

By what usual means does the stall warning system in a small aircraft alert the pilot of an impending stall?

A

An audible leer and /or a warninglight.

45
Q

What devices are used to provide warnings for a retractable landing gear system?

A

A hom or other aural device, and a red warning light or light

46
Q

How can a pilot determine that the landing gear is down and locked

A

A green light or lights and / or another type of visual indicator.

47
Q

Name at least two conditions that would activate a takeoff configuration warning system in a jet transport aircra

A

Incorrect leading or trailing edge flap position, stabilizer position, or speed brake not stowed. The manufacturer may establish other conditions

48
Q

What landing gear positions must be indicated by regulations?

A

Down and locked and up and locked.

49
Q

Under what conditions will a landing gear aural warning sound?

A

When the throttle is retarded and the landing gear is not down and locked.

50
Q

How does a takeoff configuration warning differ from a landing gear warning?

A

Takeoff warnings are usually an intermittent horns while landing gear warnings are steady

51
Q

What is the function of a Mach airspeed warning system?

A

To alert the pilot that the never-exceed airspeed limit has been reached or exceeded.

52
Q

What systems are commonly used to activate the landing gear warning systems

A

The throttles (thrust levers) and the wing flaps.

53
Q

Why do airplanes with bleed air anti-icing of the wing leading edge have an anti-ice overheat light(

A

To indicate an over-temperature condition, usually as the result of a break in the bleed air ducts.

54
Q

What warning system may be required when a nickel-cadmium battery is installed in an aircraft?

A

A battery temperature monitoring system.

55
Q

At what time would a check of a landing gear warning system normally be made?

A
  • During a landing gear retraction test.
56
Q

What is the purpose of an annunciator system?

A

To show, by means of a warning light, that some system parameter requires attention by the flight crew.

57
Q

If an aircraft with retractable landing gear has only one green light to indicate the gear is down and locked, how will the switches be connected, in series or in parallel

A

-In series.

58
Q

Where would you locate the procedures for checking and adjusting the landing gear switches?

A

In the aircraft manufacturer’s manual.

59
Q

. What is the usual means for alerting the crew of a jet transport that the cabin doors are not properly closed?

A

A warning light.

60
Q

Why are transport category aircraft equipped with a master caution and warning system?

A

To alert the crew that a malfunction has occurred and corrective action may be required.
