Runway Awareness and Advisory System - RAAS

Overview
Honeywell developed the Runway Awareness and Advisory System (RAAS), a heads-up advisory system with aural alerts to increase the pilot’s situational awareness during ground and air operations relative to the runway. Runway incursions are a leading cause of aviation accidents and fatalities, accounting for approximately $1 billion annually in damages. Loss of situational awareness can be a factor in runway incursions. 

RAAS is available on the Primus Apex and Primus Epic platforms, an easy software update to your Enhanced Ground Proximity Warning Systems (EGPWS) MK V, MK V-A, MK VII or Epic EGPWS Module (EGPWM).

Operators should contact Honeywell sales or an authorized Honeywell dealer to determine if a supplemental type certificate (STC) or service bulletin exists for a simple software upgrade.

The next evolution of Honeywell’s Runway Awareness and Advisory System - RAAS, SmartRunway and SmartLanding are software options for the Enhanced Ground Proximity Warning System (EGPWS) which increase flight crew situational awareness during taxi, take-off and landing.
