  • To allow either pilot to control the ailerons, rudder, and elevators (correct)
  • To enable autopilot functionality
  • How are the wing flaps positioned in the aircraft?

  • Manually by the pilot only
  • By altering the aileron settings
  • Using a hydraulically actuated system controlled by a single lever (correct)
  • Automatically based on flight speed
  • What ensures the security of attachments in the flight control system?

  • Electronic monitoring systems
  • Use of lightweight materials
  • Proper alignment of control cables and structural routing (correct)
  • Daily maintenance checks
  • What is the function of the dual indicating tab position indicator?

    Study Notes

    General Description of Flight Controls

    • Aircraft features all-metal flight control surfaces: ailerons, rudder, elevators, and wing flaps.
    • Dual controls for primary surfaces: ailerons, rudder, and elevators for pilot and co-pilot.
    • Wing flaps controlled by a single lever, easily accessible to both pilots, using hydraulic actuation.
    • Movable trim tabs on rudder and elevators controlled by overhead trim tab control panel.
    • Dual indicating tab position indicator displays rudder and elevator trim tab positions on the right instrument panel.
    • Fixed, ground adjustable trim tab located on the right aileron enhances control.
    • Control column, control wheel, and rudder pedals use a mechanical interconnection system including push-pull rods, bellcranks, and cables.
    • All primary control surfaces are balanced to enhance control stability and prevent flutter across various flight speeds.
    • Sealed bearings decrease friction and wear across the flight control system.
    • Control cable pulley brackets equipped with guard pins to maintain cable alignment and prevent skipping.

    Maintenance of Flight Controls

    • Control cables removal and installation require careful alignment with the structural routes.
    • Control surface balancing ensures optimal performance; includes general balance procedures and specific instructions for adjustment.

    Flight Control System

    • Controls include columns for aileron, rudder, elevator, and wing flap operations.
    • Wing flaps contribute to lift enhancement, aiding in shorter takeoff distances and lower landing speeds.
    • Continuous inspection and maintenance are critical for functionality and safety.
    • Special attention needed for security of attachments and usage of correct control cables.
    • Functional checks required for access cover parts to ensure comprehensive maintenance.
    • Rerigging may be necessary if control components are misaligned.
    • Adjustments to control systems should be minimal and documented, particularly for repairs or replacements.
