Honeywell Safety Aid Addresses Runway Excursions

Honeywell is in hot pursuit of a new family of cockpit aids to help airline pilots better manage the takeoff and landing phases of their flights. The avionics maker is close to rolling out a takeoff-roll acceleration-monitor software upgrade as part of its enhanced ground proximity warning system (Egpws), and is in the midst of researching a more comprehensive landing-and-takeoff performance monitor upgrade that will include a dedicated display area on the primary-flight or navigation displays.

The technology addresses the growing problem of runway excursions, both from flawed approaches and problematic takeoffs. The most likely cause on departure is a high-speed rejected takeoff (RTO), possibly for a failed engine, blown tire or system-warning configuration problem. Boeing says roughly 75% of RTOs are initiated below 80-kt. airspeed “and rarely result in an accident,” while about 2% occur at speeds greater than 120 kt., often leading to an overrun. In an Airbus study of incidents and accidents in 1985-2010, overruns ranked No. 1, accounting for 400 of the nearly 1,000 reported incidents.
