Honeywell has used the Paris Air Show as a springboard for its new approach and landing safety product, an upgrade of the enhanced ground proximity warning system (EGPWS).

The technology known as SmartLanding provides pilots on any kind of approach with the appropriate visual and audio advice during an unstable approach at less than 1,000ft (300m) above airfield elevation.

The technology is designed to reduce the risk of runway over-runs, the most common of all aircraft incidents, caused by unstabilised landings.

SmartLanding, is a software upgrade of EGPWS, a terrain awareness and warning system (TAWS) deployed in multiple jet and turboprop commercial aircraft.

The software works by combining satellite navigation with a terrain database containing detailed airport and runway data, which allows the airport to monitor the position of the aircraft relative to the runway and provide guidance if necessary.

Aural warnings will be triggered between 450ft and 1,000ft above runway level.

SmartLanding also has the capability to compare the barometric altitude with the GPS altitude measured by the EGPWS to detect altimeter setting errors.
