  29. Where is the flap asymmetric protection located.
  30. The trailing edge flaps are not protected against asymmetrical extension when extended by what means.
  31. Extension cf the leading edge devices is triggered by what.
  32. The leading edge annunciator on the forward instrument panel remains what colour if the leading edge devices do not match the outboard flap position.
  33. Using the alternate flap extension system, fluid from what reservoir is used to lower the leading edge devices.
  34. What is the control logic for the T/O warning system when the throttles are advanced.
  35. The stall warning vane heater will operate and the computer will be powered when.
  36. Elevator Feel Differential Pressure light on, avoid what
  37. During flight with unreliable airspeed. Control is based on power setting and what else
  38. With Jammed, sticking or faulty flight controls. What would you do to the flight control switches
  39. If one set of flaps stops because they are extended asymmetrically .Would you attempt to move the asymmetrical flaps with the alternate system.
  40. To lower the flaps using the alternate system, the flap handle is placed in what position.


  1. Hydraulic
