SECONDARY EJECTION CONTROL HANDLE.- The secondary ejection control han-dle is located on the front frame of the seat structure. A cable connects the handle to a dis-connect pulley assembly under the seat bucket. A second cable connects the disconnect pulley assembly to the firing control disconnect assembly at the top of the seat.

EJECTION CONTROL SAFETY HAN-DLE.- To prevent accidental seat ejection, a safety handle (head knocker), when placed in the down-and-locked position, prevents inadvertent actuation of all component parts of the firing control mechanism. The safety handle is identified by a yellow and black decal that reads

PULL OUT TO SAFETY EJECTION CONTROLS. A safety lock, incorporated in the safety handle, automatically locks the handle in the full-out position; the lock must be manually depressed

before the safety handle can be moved to the up (recessed) position.

POWER INERTIA REEL INITIATOR.- The inertia reel initiator is located on the rear left side of the seat, below and to the left of the inertia reel. The inertia reel initiator powers the inertia reel for automatic power retraction of the shoulder harness during the seat ejection sequence. The initiator gases discharge into a tubing segment that is filled with high-vacuum grease, and then into the inertia reel.

POWER INERTIA REEL.- The inertia reel is centrally located in the upper part of the seat

behind the headrest cushions. In the seat ejection sequence, the inertia reel provides automatic power retraction of the shoulder harness in preparation for seat ejection. The inertia reel facilitates voluntary forward movement of the crew member, and functions as a self-com-pensating restraint against involuntary forward movement resulting from excessive g-forces or other aircraft stresses. An inertia reel control handle on the left arm of the seat can be manually unlocked or locked to allow or prevent extension of shoulder harness straps. Two prestretched Dacron straps are part of the inertia reel. A flexible inertia reel cable couples the inertia reel to the inertia reel control handle.

GYRO SPIN-UP GAS GENERATOR CAR-TRIDGE.- The gas generator is attached to the pitch stabilization control (STAPAC), which is located under the seat bucket. The gas generator powers the gyro spin-up actuator, and sub-sequently powers the sear cam piston. The gas generator is a percussion-ignited device that is fired by ballistic gas pressure ported from the rocket catapult when the rocket portion fires.

VERNIER ROCKET.- The vernier rocket is a mechanically fired rocket motor located across and under the seat bucket; the vernier rocket is part of the pitch stabilization control unit. The gas generator powers the sear cam piston to fire the vernier rocket, whose rotation is controlled by the pitch rate gyro.
