Survivability Aircraft Survivability:Aircraft Survivability: The capability of an aircraft to avoid and withstand a hostile environmentThe capability of an aircraft to avoid and withstand a hostile environment History:History: Government regulations came about after massive man and machine loss during the Vietnam WarGovernment regulations came about after massive man and machine loss during the Vietnam War Regulations are stricter on military issued aircrafts, but FAA rules do apply to commercial airlinersRegulations are stricter on military issued aircrafts, but FAA rules do apply to commercial airliners

Probability of Surviving Aircraft Susceptibility (P H ):Aircraft Susceptibility (P H ): Inability for aircrafts to avoid man-made hostile environmentsInability for aircrafts to avoid man-made hostile environments Aircraft Vulnerability (P KlH ):Aircraft Vulnerability (P KlH ): Inability for aircrafts to withstand man-made hostile environmentsInability for aircrafts to withstand man-made hostile environments Aircraft Killability (P K ):Aircraft Killability (P K ): P K =P H *P KlHP K =P H *P KlH

Survivability Enhancement P S =1-P K =1-P H *P KlH Aircraft's combat survivability is enhanced when it's killability is reduced. The killability of an aircraft is reduced when the susceptibility and the vulnerability of the aircraft are reduced.
