Gulfstream received FAA approval last week for aircraft service change (ASC) 005 that lowers the maximum ramp and takeoff weights for the G500/600, enabling the twinjet models to use airports with 75,000-pound-mtow limits. Specifically, this list includes Florida’s Naples Airport (KAPF), which limits operations to aircraft with dual gear to a certified maximum gross weight of 75,000 pounds or less.
Those limitations are a problem for the G500 and G600. The G500 has ramp and maximum takeoff weights of 80,000 pounds and 79,600 pounds, respectively, while the G600 has a ramp weight of 95,000 pounds and an mtow of 94,600 pounds. The mod—which is achieved via a placard and aircraft flight manual amendments—lowers these weights to 74,900 pounds for the two large-cabin Gulfstreams, rendering them legal to use at KAPF. On the G600, it also lowers the max landing weight to 74,900 pounds, while the G500’s remains unchanged at 64,350 pounds.
