Questions and Answers

What happens to the servocontrols of an aileron if both are faulty during damping mode?

  • The aileron will droop excessively due to hydraulic failure.
  • One servocontrol remains active, allowing for normal operation.
  • Both servocontrols revert to active mode, enhancing maneuverability.
  • Both servocontrols remain in damping mode to prevent flutter. (correct)

    • Which signal is necessary for the Flight Control Computers to determine aircraft response?

  • Signals from the Air Data/Inertial Reference Units. (correct)
  • Location data from the GPS system.
  • Altitude data from the cabin pressure system.
  • Engine performance data from the fuel management system.

    • What is the purpose of aileron droop when the flaps are extended?

  • To symmetrically deflect the ailerons downwards for improved lift. (correct)
  • To disable the outboard ailerons entirely.
  • To allow for manual override of autopilot systems.
  • To increase drag and slow down the aircraft during descent.

    Study Notes

    Flight Controls - A330-200/300

    • Flight Control Computers: The computers require input from the Air Data/Inertial Reference Units (ADIRUs) to determine aircraft response (roll attitude, rate, etc.).
    • Hydraulic or Electrical Failure: If a servocontrol in active mode loses its hydraulic or electrical power, it falls into damping mode, and the adjacent one becomes active. If both aileron servocontrols fail, both enter damping mode to prevent flutter.
    • High Speed Operation: When airspeed exceeds 190 knots in a clean configuration (slats and flaps retracted), outboard ailerons are servoed to zero in autopilot mode and certain failure scenarios. This function is used up to 300 knots.
    • Ailerons Droop: This function symmetrically deflects the ailerons downwards, used when flaps are extended. When the Ram Air Turbine (RAT) is extended, the outboard ailerons are not used, and their servocontrols are switched to damping mode to reduce hydraulic consumption. On the ground with hydraulic systems depressurized, aileron droop due to gravity is acceptable.
    • Spoiler Extension for Maintenance: To access spoiler actuators, extend the flaps and secure the selector with the locking tool.
    • A330-200/300 Differences from A318/A319/A320/A321: Details on the differences in flight controls system between A330 and the other models are not included in this text.
    • Flight Control System Overview: The fly-by-wire flight control system manages primary (pitch, roll, yaw), secondary (speed brakes and ground spoilers), and high-lift (flaps and slats) functions.
