Future transport aircraft will have to meet a revised reference stall speed. Effective with type certificate applications filed after December 26, the reference stall speed is redefined as a speed not less than the 1g stall speed instead of the minimum speed obtained in a stalling maneuver. The FAA said it revised FAR 25.103 to “ensure consistent and dependable maneuvering margins, provide a higher level of safety for those cases in which the current methods result in artificially low operating speeds” and to “harmonize” FAA regulations with those of the JAA.
