Question 1

If the autopilot and flight directors are off, which FMAs will be active if the autopilot is engaged?

Answer 1

Pitch and Roll will become the active mode and the flight directors will appear.

Question 2

In vertical speed mode, is there structural speed protection?

Answer 2

Yes.

Question 3

Why are there two lights next to the APPR switch?

Answer 3

Each light represents one of the two FCCs.

Question 4

At what altitude will half bank be engaged?

Answer 4

31,600 feet.

Question 5

At what altitude will mach mode replace IAS mode?

Answer 5

31,600 feet.

Question 6

What does the SYNC button on the back of the yoke do?

Answer 6

The SYNC button synchronizes the flight director to the present flight attitude.

Question 7

Will the SYNC button work with the autopilto engaged?

No.

Question 8

What do the TOGA switches on the thrust levers do for a normal takeoff?

Answer 8

• Commands TO/TO mode as the active vertical and lateral FMAs.
• Disengages the autopilot.
• Moves the flight directors up to an optimized pitch of between 11-18º.
• Updates runway position data in the FMS.

Answer 9

• Parking Brake off.
• Flaps set for takeoff (8-20)
• V-Speeds set
• Stabilizer trim in takeoff range

Answer 10

• Command GA/GA mode as the active vertical and lateral FMAs.
• Disengages the autopilot
• Moves the flight director up to 10º
• Inhibits the half bank switch
• Holds present heading with 5º bank limit
• Sequences the FMS missed approach waypoints into the active flightplan.

Question 11

When is half bank inhibited?

Answer 11

It is inhibited during takeoff (TO/TO) mode or go around mode, or when the approach localizer has been armed.

Question 12

Will a yaw damper failure cause the autopilot to disconnect?

Answer 12

Yes.

Question 13

How can the autopilot be disengaged?

Answer 13

It can be disengaged by the AP DISC switchbar, the AP/SP switch on the yoke, or the TOGA switches.

Question 14

What is the minimum altitude for autopilot engagement?

Answer 14

600 feet.

Question 15

What is the minimum altitude for autopilot disconnect on an ILS?

Answer 15

80’ for glideslopes < 3.5º.

Question 16

What is the minimum altitude for autopilot disconnect on a non precision approach?

Answer 16

400 feet.
