L-1011 General Aircraft Characteristics: Captain's Seat (25-28)


The seating in the cockpit is designed to provide optimum comfort and visibility - resulting in less pilot fatigue. The Seat offers adjustments for:

  • Lumbar adjustment
  • Thigh adjustment
  • Longitudinal - lateral control
  • Recline control
  • Vertical control
  • Power switch
  • 4-way control switch
  • Position indicator
  • Arm rest adjustment

The Captain's and First Officer's seat are identical. Seat controls are on the inboard side of each seat. They are vertically and horizontally powered with broad adjustment ranges for the backrest, seat bottom and armrest. Electrical power is provided from AC Bus 3.

Electrical controls consist of a 4-way momentary center off toggle switch and a momentary push-button switch. The toggle switch is actuated in the direction of desired seat motion while pressing the momentary push-button switch.

There are two manual levers; one for vertical and one for lateral travel. Actuation of the levers releases a lock allowing the desired seat motion.

The recline control allows seat-back adjustment from vertical to 15• recline.
