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

Flight envelope protection has reduced LOC-I accident rates by 76% compared to third generation aircraft.

The fourth generation of aircraft has accumulated 30 years of experience since the A320 aircraft entered into service in 1988.

This represents a significant experience with more than 200 million accumulated flights, which is a strong statistical basis to illustrate the significant safety benefits of flight envelope protected aircraft to address LOC-I.

Controlled Flight Into Terrain (CFIT) accident rates

The introduction of Glass Cockpits, FMS & Terrain Awareness and Warning Systems has reduced CFIT accident rates by 89%.

Technologies to reduce CFIT were introduced progressively with Ground Proximity and Warning Systems and then Terrain Awareness & Warning System (TAWS).

Subsequently, Glass Cockpits installed on the third generation of aircraft improved navigation performance and helped to further reduce the CFIT rate.

Runway Excursion (RE) accident rates

New technologies to reduce RE accidents have recently been introduced.

Most longitudinal Runway Excursions are related to aircraft energy management. Significant improvement of RE accident rates can be expected from the introduction of real time energy and landing performance-based warning systems. Today, the proportion of aircraft equipped with such systems is too low for the overall gain to be visible but this additional safety net is a promising step change to reduce longitudinal RE occurrences.
