Pilots know that the primary job of EGPWS is to keep them from running into the ground, but they might not be aware that it can also warn them if they are about to land on the wrong runway, take off from a taxiway or cross an active runway, among a host of other incursion-preventing functions.

The Runway Awareness and Advisory System (RAAS), a $17,389 software upgrade to EGPWS, was recently awarded FAA certification, according to manufacturer Honeywell, clearing the way for STC approvals in a number of airplanes. The enhancement, said Honeywell, provides 10 specific aural alerts to pilots, each designed to prevent runway and taxiway incursions.
