Manual override handle Yes
Timers No
Seat adjustment Up/down Actuator operated 28 Vdc
Arm restraints No
Leg restraints Yes, two garters
Oxygen supply Bottled emergency oxygen
Main oxygen system connection
Personal survival pack Yes, landscale, Liferaft option available
Aircrew services Personal equipment connector (PEC) provides
connections for
- main oxygen
- back-up oxygen
- emergency oxygen
- anti-g suit
- mic/tel
Command ejection Yes
Canopy jettison No
Miniature detonating cord Yes
Interseat sequencing system Yes, through command delay breech unit
Mk. 10- Seat firing handle pulled causing seat initiation cartridge to fire
- Harness retraction unit operated, command firing initiated
- Primary cartridge fired causing inner and intermediate pistons to rise, releasing top latch
- Seat rises up guide rails
- Miniature detonating cord trip initiates canopy fracturing system
- Secondary cartridges fire in turn as seat rises
- Electrical connections separate disconnecting seat actuator circuit, IFF
switch and oxygen regulator supply lead
- Aircraft portion of main oxygen generating system block separate
disconnecting main and back-up oxygen
- Personal equipment connector aircraft portion disconnects from seat portion
- Anti-g suit hose disconnects
- Leg restraint lines draw back and restrain aircrew’s legs
- Leg restraint lines become taut and rivets shear, freeing lines from floor brackets
- Trip rods withdraw sears from drogue gun and barostatic time-release units
- Emergency oxygen trips
- Remote rocket initiator operated by static line, cartridge fires to ignite rocket pack
- Rocket pack sustains upward thrust of ejection gun, diverging trajectories for front and rear seats
- After delay mechanism has operated, drogue gun piston fires
- Ejected piston withdraws closure pin from closure flaps of drogue parachute pack and deploys drogues.
- Deployment of drogues stabilize and retard the seat and aircrew
- Low altitude/High speed -
- Seat descends stabilised by drogues
- Barostatic time-release unit completes run and fire
- High speed/high altitude -
- Barostatic capsule operates to prevent parachute deployment above pre-determined altitude
- Barostatic controlled g-switch delays parachute deployment above 7000 ft until speed and g-force are reduced
- Barostatic time release unit operates below pre-determined altitude, completes run and fires
- Manual separation (override) used if automatic system fails
- Gas from cartridge used to
- Free drogue shackle link
- Release parachute mechanical lock
- Operate upper harness locks and lower harness release mechanism to free lower harness lugs, negative-g straps, leg restraint lines and personal equipment connector man portion
- Drogues withdraw parachute from container
- Sticker straps momentarily hold aircrew in seat
- Parachute develops, lifts aircrew and survival pack from seat and pulls sticker clips from clips causing aircrew and seat to diverge
- Normal parachute descent follows
- Aircrew releases either of two quick-release connectors to lower survival pack to end of line
- Survival pack opened manually when necessary

If you look at the photo below, you can plainly see that the seat has brought the pilot out of the aircraft and is already righting itself prior to main chute deployment and seperation!

"All modern aircraft have 4 dimensions: span, length, height and politics.
TSR-2 simply got the first 3 right. ”
— Sir Sydney Camm
