Loss Of Control In-flight (LOC-I) accident rates

 

Flight envelope protection has helped reduce LOC-I fatal accident rates by 89% compared with third-generation aircraft

The fourth-generation aircraft have accumulated over 30 years of in-service experience since the A320 first entered into service in 1988. This represents more than 223 million accumulated flights by the end of 2021, 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 89% lower for fourth-generation aircraft when compared with third-generation aircraft.

Controlled Flight Into Terrain (CFIT) accident rates

 

The introduction of glass cockpits, FMS & TAWS has helped to reduce the CFIT fatal accident rate by 86%

Technologies to reduce CFIT accidents were introduced progressively with the Terrain Awareness and Warning System (TAWS).

Glass cockpits installed on the third generation of aircraft improved navigation performance due to the introduction of a Flight Management System (FMS) and navigation displays that helped to further reduce the CFIT accident rates.

Runway Excursion (RE) accident rates

 

Technologies to reduce RE accidents have been available for over 10 years

Most longitudinal RE accidents are related to aircraft energy management. An improvement of RE accident rates should be expected with the introduction of real-time energy and landing performance-based warning systems, such as the Runway Overrun Protection System (ROPS) available for Airbus aircraft. In 2021, the number of aircraft equipped with ROPS has increased to 9% of the worldwide fleet.
