2、he F-18 fighter aircraft, including its 17 foot diameter main parachute. A test pilot ejected from the X-31 over Edwards Air Force Base, CA. The pilots calculated descent rate was over 28 feet per second. The parachute landing fall resulted in multiple injuries.Photo of the x-31 jet in flightX-31 Ex
3、perimental AircraftLesson(s) Learned: In the case of an over land ejction and depending on pilot/payload weight, the 17 foot diameter main parachute in the F-18 egress system can allow a sufficiently high descent rate as to make parachute landing fall injury highly probable.Recommendation(s): Consid
4、er use of a larger diameter main parachute, especially where ejection is likely to be over land.Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-Evidence of Recurrence Control Effectiveness: N/ADocuments Related to Lesson: N/AMission Directorate(s): N
