EJECTION
SEATS
First Mk6 ejection was on 28th November 1966
Over 280 Mk6 ejection seats currently in service
SEATS
Introduction of the rocket pack to the range of Mk. 4 and Mk. 5 ejection seats created the basic Mk. 6 and Mk. 7 ranges respectively. The Mk.6 ejection seats have saved over 256 aircrew lives around the world and there are still over 250 Mk.6 seats currently in service today.

- The pilot pulls the face screen seat firing handle
- Canopy jettison initiated
- Ejection gun fires, seat moves up guide rails and the secondary cartridges fire
- Emergency oxygen tripped
- Aircrew services disconnect
- Leg restraints operate
- As seat rises, static line initiates time-delay which fires drogue gun after 0.5 seconds
- As seat rises, static line initiates time-release unit
- 22 in. dia then 5 ft dia drogues stabilise and slow seat
Above 10000ft
- Barostat prevents operation of time-release mechanism
High speed
- g-restrictor prevents operation of time-release mechanism
Below 10000ft, (low speed)
- 1.5 sec after initiation of time-release unit the plunger releases scissor shackle to transfer pull of drogue to lifting lines of parachute, releasing it from seat
- Release face blind
- Harness and leg lines released from seat
- Drogues deploy main parachute, pilot separates from seat
- Normal descent
- Manual separation system available if necessary. Operation of manual separation handle fires a cartridge that operates a guillotine, severing the parachute attachment line, linkages function releasing parachute harness, negative-g strap, PEC and leg restraint cords.
- Freeing parachute from seat.
- Aircrew can then use rip cord to operate parachute.
