- Maximum operating limit speed. Viewed on the airspeed indicator as a red barber pole. Like always in aviation, red means not good.

Generally 1.5 Vs with slats and flaps 48.
37,715 lb= 38-22=16 x2=32 +100 =132 kts - V1
- Engine failure speed, the speed at which 1 engine is assumed to become inop. Before this speed the takeoff can be aborted for any reason. Above V1, the PF releases control of the power levers and the PNF then guards the power levers. Aborting above V1 does not guarantee adequate runway length to stop and in many cases there is more energy, due to the weight and speed than the brakes can absorb.
- Vmbe
- Maximum brake energy speed is the maximum engine failure speed V1 at which he maximum demonstrated brake energy is not exceeded. The brakes can absorb the energy required to stop the aircraft. Above this speed the brakes may overheat and become worthless. In some cases Vbme can be lower than V1 making the takeoff unsafe, as the brakes may not be able to stop the aircraft should the takeoff be aborted.
- V2
- Takeoff safety speed. The initial speed reached by the aircraft before it is 35ft. above the takeoff surface with one engine inoperative.
