A

Audio Panel

60
Q

If the CDI source is changed while the AP is engaged in NAV mode, what happens?

A

AP reverts to Roll mode, NAV must be reselected

61
Q

In cold ambient temperatures, what speed would be beneficial to help with landing gear operation?

A

113kts, particularly for the retraction of gear.

62
Q

How long will the backup artificial horizon and flood light have power for?

A

1.5hrs

63
Q

How much should the takeoff distance be modified for wind?

A

Reduce by 3% for each 4 knots of headwind, and increase the distance by 5 knots for each 2 knots of tailwind.

64
Q

How much should the landing distance be modified for wind?

A

Reduce distance by 2% for each knot of headwind, increase total distance by 4% for each knot of tailwind

65
Q

In regards to the controls, do they use control rods or cables?

A

Control rods for ailerons and elevator, cable for the rudder

66
Q

What is the purpose of the variable elevator backstop?

A

Limits the elevator up travel to 13° as soon as the power setting of BOTH engines exceeds 14.5” at sea level with the flaps up. This is 2.5° less than the 15.5° maximum deflection.

If the power is less than 14.5” or the flaps are deployed then full deflection will become available.

67
Q

How does the Carbon Monoxide detector work?

A

Will alert within 5 minutes or less if the carbon monoxide reaches 50 parts per million by volume. Alert will happen faster if intensity is greater, instant alert at 400 parts per million.

68
Q

How is the gear operated?

A

Electrically actuated hydraulically operated.

69
Q

How long does gear extension typically take?

A

6-10 seconds

70
Q

Does the hydraulic pressure keep the gear extended or retracted?

A

Retracted, so that if pressure is lost the gear will fall.

71
Q

How is the landing gear locked in the down position?

A

Downlock hooks which are assisted by springs to maintain force.

72
Q

When will the warning horning sound for gear not extended?

A

Any of the throttles below 14” with gear retracted, OR if the flaps are put in the LDG stage with gear retracted

73
Q

What is the gear up and gear down speed?

A

Gear up = 156kts, gear down 194kts (Vne)
