Flight envelope protection introduced with generation 4 aircraft has helped reduce LOC-I fatal accident rates by 90% compared with generation 3

The generation 4 aircraft have accumulated over 30 years of in-service experience since the A320 first entered into service in 1988. This represents more than 257 million accumulated flights by the end of 2023, which is a strong statistical basis illustrating the significant safety benefit of fly-by-wire enabled and flight-envelope-protected aircraft to address LOC-I accidents. The rate of LOC-I accidents is 90% lower for generation 4 aircraft when compared with generation 3 aircraft.
