What We Do
MK17 Ultra Lightweight
Specifically developed for optionally-manned and basic trainer aircraft where weight and size is critically important
The Martin-Baker Mk17 Ejection Seat is an ultra-lightweight, compact and simple design that has been specifically developed for optionally-manned aircraft and basic trainer aircraft where Seat weight and size are critically important.
The Seat will provide safe escape capability for aircraft speeds in the range 60 knots (at ground level, on the runway) to 250 knots calibrated airspeed (KCAS) and altitudes from sea level to 25,000 ft. Capable of providing safe escape for aircrew in the weight range 103lbs to 245lbs (47kg to 111kg) nude, the Mk17 escape system will proved safe means of escape from a basic training aircraft, a feature which hitherto has been unavailable.
Life cycle cost considerations are also a primary design driver, resulting in a Seat design with only 50% of the pyrotechnic device count of other modern ejection seats with minimal maintenance overhead.
