SurvivabilitySurvivability
• Aircraft Survivability: Aircraft Survivability: • The capability of an aircraft to avoid and The capability of an aircraft to avoid and
withstand a hostile environmentwithstand a hostile environment
• History:History:• Government regulations came about after Government regulations came about after
massive man and machine loss during the massive man and machine loss during the Vietnam WarVietnam War
• Regulations are stricter on military issued Regulations are stricter on military issued aircrafts, but FAA rules do apply to commercial aircrafts, but FAA rules do apply to commercial airlinersairliners
Probability of SurvivingProbability of Surviving
• Aircraft Susceptibility (PAircraft Susceptibility (PHH): ):
• Inability for aircrafts to avoid man-made hostile Inability for aircrafts to avoid man-made hostile environmentsenvironments
• Aircraft Vulnerability (PAircraft Vulnerability (PKlHKlH): ):
• Inability for aircrafts to withstand man-made Inability for aircrafts to withstand man-made hostile environmentshostile environments
• Aircraft Killability (PAircraft Killability (PKK): ):
• PPKK=P=PHH*P*PKlHKlH
Survivability EnhancementSurvivability Enhancement
PS=1-PK=1-PH*PKlH
•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.
