 The straps of the safety harness can be clicked into the buckle in any order. Turning the unlocking control through a 1/4 turn, either clockwise or anticlockwise, releases the two shoulder straps and the lap belt. Pressing the control located on the top of the buckle releases the shoulder straps alone. The inertial reel locking control is located in the coat storage compartment.

 4. Operation/Control and Indicating
________________________________
 A. Captain and First Officer Seats
 (1) Vertical travel
 (a) Manual control (Ref. Fig. 006)
 1_ Up travel
 To move the seat in the up direction pull the control handle,
 marked V and located on the inboard side of the seat pan,
 upwards in order to unlock the seat. Then, by taking your
 weight off the seat, adjust the seat to required position,
 then release the handle. A gas cylinder compensates for the
 weight of the seat (2 grasp handles are located above each
 pilot seat).
 2_ Down travel
 To move the seat in the down direction, pull the control
 handle upwards in order to unlock the seat. The weight of the
 occupant is sufficient to move the seat downwards. To lock the
 seat in position, release the handle. The down movement is
 slowed down by means of a gas cylinder.
 NOTE : The control handle V acts on a ball-nut/screw system____
 ensuring vertical movement of the seat.

 (b) Vertical electrical control (Ref. Fig. 007) If the circuit is supplied with power, place the control switch located on the inner side of the seat pan in the up or down position until the seat reaches the required position. Seat movements are obtained by the gear motor associated with the ball-nut/screw system. The movements are limited by stops and an overtorque detector integrated in the gear motor assembly.
