"I used to fly an aircraft where VR was always greater than V2. We never calculated V2 as it was assumed we would never fly below VR! "
The Victor MK2. With inboard engines, there wasn't a huge assymetric effect, although VMCA was a factor in a double assymetric go around as the rudder was quite small. The four speeds we used to calculate before take off were V1, VR, VPAT which was the heavyweight circuit pattern speed and VEPS (V Emergergeny Parachute Stream) - the speed we had to get below after touchdown at takeoff weight before we could deploy the brake chute to prevent shredding it.
The MK1 Victor was operated to military performance which being calculated in the early 1950s was essentially "as is" and was gross performance. The MK2 was the first aircraft to be powered by the RR Conway and as part of the Conway's cetifiction process, the aircraft worked to BCARs net performance, hence the slightly complicated calculations.
