1. B757 Review Questions

2. AutoFlight At what RA does flare mode engage? 45 feet RA

3. AutoFlight When does autopilot electrical isolation occur? With at least two generators working and three autopilots armed for the approach.

4. AutoFlight After electrical isolation, what is the power source for the center autopilot? Battery/Standby system

5. AutoFlight If an engine generator were to fail on a multi autopilot approach above 200’, what would happen to the AC power distribution to the auto pilots? After the generator failure the center autopilot switches from center AC bus to its normal source of power, Left AC bus.

6. AutoFlight If during a land three approach an AP were to fail, could the approach be continued to an auto land safely? Yes. A single fault would not prevent the remaining two autopilots from completing the auto landing.

7. AutoFlight Rudder control is added by the AP when? Only during multiple AP approaches.

8. AutoFlight When is GA mode armed? When the flaps are not up or GS is captured

9. AutoFlight Can the AP disconnect bar disconnect all 3 AP? Yes, but will not silence the horn

10. AutoFlight Is over/under speed protection available in VS mode? No

11. AutoFlight What percentage is scheduled on the TMC for CLIMB 1, and CLIMB 2? 94% and 88%

12. AutoFlight What is the scheduled pitch attitude after takeoff at 400’ V2 + 15

13. AutoFlight During a coupled missed approach, an engine fails just as the GA switch is activated. Which action must the pilot take to prevent yaw from rolling the aircraft? None. There is rudder input from the auto flight system preventing a yaw from rolling the aircraft. However, once a pitch or roll command is initiated by the pilot, he must now manually deflect the rudder.

14. AutoFlight When is the GA mode armed? When the flaps are not up, or GS is captured.

15. AutoFlight Do the autopilots do anything different to the stab trim during a LAND 2 approach? Yes. At 330 feet RA and increment of nose up trim is automatically applied.

16. AutoFlight Can you dispatch with both Yaw Dampers inoperative? No, check MEL

17. AutoFlight When does rudder channeling commence on a multi channel approach? Below 1500’ RA

18. AutoFlight When is the normal bus-tie operation isolated/inhibited on a multi channel approach? 200’ RA

19. AutoFlight What does the autopilot amber annunciator light indicate? Indicates that some operating mode of the engaged autopilot has failed, but the auto pilot remains engaged.

20. AutoFlight Is over speed protection available in Flight level change mode? Yes.

21. AutoFlight What is the main power source of the left and center FCC’s? Left main AC bus and Center AC bus.

22. AutoFlight True or false: the autopilot trims nose up at 330’ on CAT III land II approach? True.

23. AutoFlight Is manual rudder input restricted during auto land operation? Yes, manual rudder input is restricted due to A/P rudder control from 1500 feet through GA.

24. AutoFlight What is a good way to monitor the center FCC in flight? Use the center Autopilot

25. AutoFlight TRUE/FALSE: During an Autoland Roll Out mode operation the Autopilots lower the nose wheel to the runway at 5 feet R/A plus 2 seconds with the pitch attitude less than 2 degrees TRUE

26. AutoFlight Should you follow the flight director pitch bar at lift off? No, you would probably get a tail strike

27. AutoFlight What will the A/T system do when the thrust reversers are selected after landing? A/T mode disengages

28. AutoFlight Before the autoflight system will climb using FLCH,________ and then the desired AFDS pitch change is made A higher altitude has to be set in the Altitude window

29. AutoFlight During the takeoff roll, EPR appears in both the FMA A/T windows until what speed? 80 knots

30. AutoFlight All AFDS modes can be disengaged by selecting another command mode or by disengaging the A/P and_____ turning off the Flight Directors

31. AutoFlight During the takeoff roll, the F/D pitch bar commands a fixed attitude of 8 degrees nose up

32. AutoFlight Can the A/T be operated independently of the flight director and the autopilot? Yes

33. AutoFlight After liftoff, the F/D pitch bar initially moves to an attitude of 15 degrees nose up

34. AutoFlight TRUE/FALSE: The vertical speed mode will command the aircraft to leave the current altitude when a new altitude mode has not been selected. TRUE

35. AutoFlight When GA is engaged, the AFDS controls pitch and roll while the A/T Increases thrust to establish a 2,000 fpm climb

36. AutoFlight TRUE/FALSE: During the autoland rollout mode operation, rollout guidance continues to full stop or until the A/Ps are disengaged. TRUE

37. AutoFlight TRUE/FALSE: During the autoland rollout mode operation the F/D roll command bar provides directional steering information. TRUE

38. AutoFlight Active FMA modes are displayed in large green letters in the top part of the annunciator windows. Armed FMA modes are indicated _______underneath the green annunciations. In smaller, white letters

39. AutoFlight How many FCCs are normally used for A/P operations during an automatic approach, landing and rollout, as well as the initial phase of a go-around? Three

40. AutoFlight TRUE/FALSE: The V/S mode has no stall or overspeed protection and annunciations TRUE

41. AutoFlight When the LOC is captured, the AFDS will command up to _____ degrees regardless of the MCP bank angle selector. 30
