Mk15 Ejection Seat
The decision to develop the Mk15 seat followed research carried out among military operators of the Pilatus PC-7 MkII. This showed that, while they were satisfied with the aircraft’s performance in its role of trainer, many would have liked the extra safety and reassurance of a high-quality ejection system.
With the addition of ejection seats, the PC-7 MkII gains a greater degree of similarity with operational aircraft and students can receive early instruction on the disciplines necessary for working with this type of safety device.

Mk15 Ejection Seat
Featured in:
- PC-7
Mk15 Ejection Seat
- Seat firing handle is pulled, causing seat initiation cartridge to fire
- Seat pan front cross beam latches release, PSP drop down panel lowered to allow pilot’s legs to assume correct position for ejection
- Harness retraction unit operated
- Negative-g strap released
- Primary cartridge fires
- Canopy fragmentation bullet fires
- Top latches disengage, seat rises up rails
- Drogue gun time-delay mechanism initiated
- Barostatic time-release unit (BTRU) initiated
- Emergency oxygen supplied to aircrew
- Drogue deploys to stabilise and decreases 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)
- Harness reel strap and parachute canopy withdrawal line released
- Drogue gun cartridge fires to deploy drogue
- Lower harness locks released
- Drogue extracts and deploys the main parachute canopy
- Main parachute canopy fully deploys and lifts aircrew and Personal
- Survival Pack (PSP) from seat
- PSP manually lowered on drop line below aircrew
- Normal parachute descent follows
- Manual opening of PSP
- Manual initiation of liferaft inflation (if carried)
