What is the maximum altitude at which the Martin-Baker ejection seat functions safely?

The Martin-Baker ejection seat is designed to operate safely within a specified altitude range to ensure effective ejection and parachute deployment. The maximum altitude of 35,000 feet allows for the proper functioning of the seat’s mechanisms and the successful deployment of the parachute in conditions critical for survival during high-altitude flight. At this altitude, the atmospheric pressure is still sufficient for the ejection seat to perform effectively, enabling the ejected pilot to have an adequate altitude for parachute deployment and descent.

This operational limit is established through extensive testing and safety protocols to maximize pilot survivability in emergency situations. Choosing an altitude that exceeds this limit may compromise the ejection system's effectiveness and the overall safety of the pilot.
