Aircraft Security & Alert Systems has introduced a new series of locks specifically designed for large-cabin business jets. The locking systems have already been designed for the Global Express, Challenger 604, Gulfstream IV, V, 200, the Falcon 900 and 2000 and the Embraer Legacy. Keys are cut vertically and horizontally, can only be duplicated by ASAS and are tailor made for the owner of the aircraft. Each set of locks has up to 21 individual locks for every door and access panel on the aircraft. The locks mount flush with the airframe and align vertically so pilots can tell at a glance if all panels and doors are properly locked. The hardened steel locks have two sets of tumblers for added security; standard locks have only one. Lock sets range in price from $100 to $2,000.
