Autoflight

Question 1

Theautopilot system can detect the degradation of a specific autopilot mode. What indication(s) results when an engaged mode degrades?

Answer 1

• The autopilot remains engaged in an attitude−stabilizing mode based on inertial data
• A persistent condition is annunciated by an amber line drawn through the affected Flight Mode Annunciation (FMA)
• Further degradation results in EICAS caution message AUTOPILOT.

Question 2

What does an AFDS status annunciation of LAND 3 indicate?

Answer 2

Three autopilots are engaged and operating normally for an automatic landing. The autopilot system level of redundancy is such that a single fault cannot prevent the autopilot system from making an automatic landing (fail operational).

Question 3

Changes in autoland status below 200 feet, other than a transition to NO AUTOLAND are ____.

Answer 3

Inhibited

Question 4

Howdoes the autothrottle apply thrust when operating in the THR mode?

Answer 4

The autothrottle applies thrust to maintain the vertical speed required by the pitch mode

Question 5

What flight envelope protection is provided by the autopilot?

Answer 5

• Bank angle
• Stall (above 500 feet)
• Overspeed

Question 6

When does the autothrottle disconnect automatically?

Answer 6

The autothrottles disconnect automatically when:
– A fault is detected in the engaged autothrottle mode.
– Either reverse thrust lever is raised to the interlock position.
– The FMC selector is switched between FMCs.
– Both engines are shut down.

Question 7

Whenthe CLB CONswitch on the MCP is pushed in flight, what is accomplished?

Answer 7

With two engines operating, changes the engine thrust limit to the FMC selected climb thrust. With only one engine operating, changes the thrust limit to maximum continuous (CON).

Question 8

The MCP IAS/MACH window displays ____ knots when power is first applied.

Answer 8

200

Question 9

What is accomplished by pushing the LNAV switch on the MCP?

Answer 9

Arms, engages, or disarms LNAV as a roll mode.

Question 10

After localizer and glideslope capture, the localizer and glideslope modes can be disengaged only by what?

Answer 10

• Disconnecting the autopilot and turning both F/D switches to OFF
• Engaging the go−around mode
• If above 1500 feet, by de−selecting APP (roll and pitch revert to default modes)

Question 11

During an approach after LOC and G/S capture, how do you disengage the LOC and G/S?

Answer 11

After localizer and glideslope capture, these modes can be disengaged by one of the following methods:
– Disengaging the autopilot and turning both flight directors off
– Engaging the go−around mode
- If above 1500 feet, de−selecting APP (roll and pitch revert to default modes)
