DUNCAN AVIATION has modiÌed a Dassault Falcon 900 business jet to comply with reduced vertical-separation minimum (RVSM) regulations now in force on North Atlantic routes. The update involved the upgrade of both air-data computers, a visual inspection of skin waviness around the pitot and static ports and a test ßight to check height-keeping performance.
Lincoln, Nebraska-based Duncan says that a second Falcon 900 is being modiÌed, while RVSM work is under way on two Falcon 50s. RVSM rules were introduced to the North Atlantic on 27 March, barring non-compliant aircraft from ßight levels between 33,000ft (10,000m) and 37,000ft.o
