Cessna last month announced the availability of special Service Bulletins for operators who want to upgrade their airplanes with Honeywell’s runway awareness and advisory system (RAAS), a roughly $17,000 optional add-on for the enhanced ground proximity warning system (EGPWS). Cessna service centers can perform the RAAS software and hardware updates for operators of Citation Bravos, Encores, Excels and Xs equipped with EGPWS.
RAAS is designed to reduce the chances of runway incursions by providing aural alerts to pilots during taxi, takeoff, final approach, landing and rollout. Using GPS data, RAAS issues advisories based on aircraft position compared against airport information stored in the EGPWS runway database.
Besides a software upload, RAAS consists of a PCMCIA card that activates additional features in existing Mark V and VII EGPWS computers, according to Honeywell.
