stormyweathers, you may not have interpreted the question in the same way which I have.
The question refers to an ‘escape’ procedure, which I relate to an emergency procedure with turn (ETP), it is only used with an engine failure (OEI); hence the reference to V2, etc.
If the question is for all engines (AEO) – a very unusual procedure, then the speed to be flown should be specified in the procedure. This speed will affect the obstacle clearance achieved, and if it is V2 then either a bank limit or a speed addition to maintain stall margin should also be specified for the turn.
More details required. See FE Hoppy #13 and FlightPathOBN #15
