A crewmember (12) is positioned within an ejection seat or other escape device (10). The escape device (10) is ejected from the aircraft or other flying vehicle when it is desired to effect an escape. At the start of ejection, the altitude, sink rate and roll angle of the escape device (10) are determined, by appropriate sensors (128, 132). A microprocessor (66) is used for dividing the altitude by the sink rate to obtain a first time value. The microprocessor (66) is used to divide the roll angle by a desired rate of roll angle correction, to obtain a second time value. The second time value is subtracted from the first time value to obtain a third time value, tc. In response to tc being larger than a predetermined value, the microprocessor (66) controls separation to subject the crewmember (12) to a relatively low injury risk level. In response to tc being smaller than said predetermined time value, the microprocessor (66) controls separation to occur faster, attended by the crewmember (12) being subjected to a higher injury risk level.

A method of effecting crewmember escape from a flying vehicle, comprising: providing the vehicle with an escape device which can be separated from the vehicle; positioning the crewmember in said escape device; and separating the crewmember and the escape device from the vehicle when it is desired to effect an escape, including: at the start of separation sensing the altitude above ground of the escape device, the sink rate of the escape device and the roll angle of the escape device; dividing the altitude above ground by the sink rate to obtain a first time value which increases with an increase in altitude above ground and decreases with an increase in sink rate; dividing the roll angle by a desired rate of roll angle correction to obtain a second time value which increases with roll angle and decreases with the desired rate of roll angle correction; subtracting the second time value from the first time value to obtain a third time value; and in response to the third time value being larger than a predetermined time value, controlling the escape to subject the crewmember to a relatively low injury risk level, and in response to the third time value being smaller than said predetermined time value, controlling the escape to occur faster, attended by the crewmember being subjected to a higher injury risk level.
