Flight Controls

  1. Rudder
    • Manually actuated through a system of cables, torque tubes, and push rods
    • Deflection limits- 30°
  2. Spoiler
    • 2.5 inches tall
    • Manually actuated through a system of cables, torque tubes, and push rods
    • -- Deflection limits-
    • -- Retracted- inboard -14° - 68°, outboard -14° - 72°
    • -- Extended- inboard 14° - 72°, outboard 14° - 76°
  3. Elevator
    • Manually actuated through a system of cables, torque tubes, and push rods
    • Deflection limits- 12° down - 25° up
  4. Flaps
    • Double slotted fowler type
    • Electrically powered, mechanically position, hydraulically actuated
    • Sensor is on Right side and AC powered
    • -- Deflection limits- Main 10 – 30°, Aft 5 – 13.5°
    • --Travel Times-
    • -- 0-10°- 2.5 secs, 10-30°- 3.5 secs, 0–30°- 6 secs
    • -- G limits- Flaps up -1–3.2G, Extended- 0–2.0G
    • -- Aft flaps are mechanically linked to the main flaps
    • -- FLAP ASYM if 7° difference between main flaps. Power is cut off to flaps when sensed
  5. Speed Brakes
    • Electronically controlled and hydraulically actuated
    • Kill wing lift
    • Extend at different speeds
    • -- In flight- 2.6sec, On ground- .6 sec
    • Automatically retract at approximately 88% N1 on ground or when flaps > 10°
    • Deflection- 36° inboard and outboard
    • White SPD BRAKE EXT annunciator in on anytime the speed brake is not fully retracted
  6. Trim
    • Located on each wing tip, rudder, and entire horizontal stabilizer
    • Wing tabs displace up to 25° up or down, 25 seconds stop to stop
    • Rudder tab deflects up to 25° either side, 48 seconds stop to stop
    • Pitch trim 1.5° nose down - 12° nose up, 14 seconds from stop to stop
    • --Note pitch trim instrument markings are red lined at 1.4° down and 11° up
    • Take off trim- 5.6 – 6.4°
    • Emergency Pitch Trim- Moves 1/3 rd speed of normal trim. Uses autopilot servo. 45 seconds from stop to stop.
