    256 knots
  27. On the 777-300ER aircraft to protect against inadvertent deployment during cruise, flap and slat extension from the UP position is inhibited when
    speed is more than 275 knots or altitude is above approximately 20,000 feet.
  28. What are the flap limit speeds on the 777-300ER for flaps 25 and 30?
    • Flaps 25.....200 knots

    275 knots
  31. Before liftoff, the thrust asymmetry compensation (TAC) system ________________ for the failed engine.
    does not fully compensate....
  32. The thrust asymmetry compensation (TAC) system significantly reduces uncommanded flight path changes associated with an engine failure or thrust differential by automatically adding rudder to minimize yaw.  (T or F)?
  33. In-flight, at what flap settings are Speedbrake operations allowed.
    ALL flap settings.
  34. In the Secondary Flap/Slat Mode, what will happen if the aircraft exceeds 256 knots (777-300ER) with the slats fully extended?
    The slats automatically retract to the mid-range position and LOAD RELIEF is displayed.
  35. Cargo handling and fueling operations are powered by which electrical bus?
    Ground Handling Bus
  36. What occurs automatically if both AC transfer busses lose power inflight?
    The RAT deploys and the APU starts.
  37. The Electrical Load Management System (ELMS) provides load management and protection to ensure power is available to critical and essential equipment. (T or F)?
