On an allied subject and that is FD reading after VR. Assuming engine failure just after VI where the aircraft has not yet reached VR on one engine. Providing the rate of rotation is correct it is my understanding that the FD will give the correct angle to maintain V2. If the rotation rate on one engine is slow then it is probable the FD will not give V2 but a different angle in order to maintain the airspeed at some figure well beyond V2.
Question therefore: If the engine failed while on the runway at V1 and the take off is continued, and the pilot is slow to commence rotation with commensurate increase in airspeed above the scheduled V2, does the FD command V2 or some other speed and what speed is that. It is known that the FD will adjust its angle to maintain the speed at which the engine failure occured after airborne - but how does the FD change with slow rotation rate if at all?
