Mk11 Ejection Seat
The Martin-Baker Mk11 seat embodies all the design features of the company’s more sophisticated escape systems, but at reduced weight and size. The Mk11 seat design offers a great deal of flexibility, allowing each installation to be tailored specifically to an individual customer’s requirements.
The Mk11 seat is fitted in the Pilatus PC-9 and PC-7 and PZL L-130.

Mk11 Ejection Seat
Featured in:
- PC-9
- PC-7 MkII
- PZL-L130
Mk11 Ejection Seat
- Seat firing handle is pulled, causing seat initiation cartridge to fire
- Command firing initiated (if selected)
- Harness retraction unit operated
- Primary cartridge fires
- Top latches disengage, seat rises up rails, secondary cartridges fire progressively
- Canopy breakers shatter canopy
- Drogue gun time-delay mechanism initiated by trip rod
- Barostatic time-release unit (BTRU) initiated by trip rod
- Seat services and command ejection quick-disconnects disconnected
- Emergency oxygen supplied to aircrew
- Leg restraint lines restrain aircrew’s legs, lower attachments shear
- Drogue deploys after delay, to stabilise and decrease velocity of seat
- Barostatic time release unit monitors the altitude
Above pre-determined altitude
- Seat falls, stabilised by drogue
- Emergency oxygen supply continues
Below pre-determined altitude
- BTRU mechanism operates, cartridge fires
- (If BTRU fails, manual deployment also available by pulling manual override handle)
- Drogue shackle freed
- Parachute mechanical lock freed
- Upper harness locks released
- Lower harness lock mechanism releases lower harness lugs, negative-g strap and leg restraint lines
- Aircrew momentarily held in seat by sticker straps
- Drogue extracts and deploys the main parachute canopy
- Main parachute canopy fully deploys and lifts aircrew and personal survival pack (PSP) from seat.
- Reaction to sticker clips ensures divergence of aircrew and seat
- PSP manually lowered on drop line below aircrew
- Normal parachute descent follows
- Manual opening of PSP
