V1, Vr and V2 speed of aircraft.
V1, Vr and V2 speed of aircraft. In aviation, V-speeds are standard terms used to define air speeds important or useful to the operation of all aircraft. These speeds are derived from data obtained by aircraft designers and manufacturers during flight testing for aircraft . The speed will vary among aircraft types and varies according to factors such as aircraft weight, runway length, wing flap setting, engine thrust used and runway surface contamination, thus it must be determined by the pilot before takeoff. So what really V1 , Vr and V2 speeds are . Let us discuss it below: V1 Speed V1 is the decision speed (sometimes referred to as critical engine speed or critical engine failure speed) by which any decision to reject a takeoff must be made. Above V1, the takeoff must be continued unless there is reason to believe that the aircraft will not fly. An engine failure identified not later than V1 should always result in a re
