U.S.: United States. Usable Fuel: Fuel available for flight planning. V1: Takeoff Decision Speed. The distance to continue the takeoff to reference zero will not exceed the scheduled takeoff field length if recognition occurred at V1 (accelerated-go). The distance to bring the airplane to a full stop (accelerated-stop) will not exceed the scheduled takeoff field length given maximum brakes are applied at V1. V2: Takeoff Safety Speed. This climb speed is the actual speed at 35 feet above the runway surface as demonstrated in flight during takeoff with one engine inoperative. V35: This climb speed is the actual speed at 35 feet above the runway surface as demonstrated in flight during takeoff with both engines operating. VA: The maneuvering speed is the maximum speed at which application of full available aerodynamic control will not over stress the airplane. VAPP: The landing approach climb airspeed (1.23 VSR1) with flaps 15°, landing gear UP. VBE: Maximum Brake Energy Speed. The maximum speed from which a stop can be accomplished within the energy capabilities of the brakes. VENR: Single-engine enroute climb speed. VFE: Maximum flap extended speed. The highest speed permissible with wing flaps in a prescribed extended position. VLE: Maximum landing gear extended speed. The maximum speed at which an airplane can be safely flown with the landing gear extended. VLO: Maximum landing gear operating speed. The maximum speed at which the landing gear can be safely extended or retracted. VMCA: Minimum airspeed in the air in the takeoff configuration at which directional control can be maintained, when one engine is suddenly made inoperative. VMCA is a function of engine thrust which varies with altitude and temperature. The following VMCA's presented were determined for maximum thrust: Flap 7° - 92 KIAS Flap 15° - 90 KIAS |
