our company requires us to start the call V1 5 knots prior to V1. it is usually in this ''gray zone'' that th e sim instructor pulls the engine.
Certainly if you have a failure prior to V1 you reject...the closeness of all these things is impossible to write.
guppy. you lose the engine, you recognize it, you keep centerline with rudder and you start to trim while you are still on the ground/runway, accelerating to Vr
I'm not saying to trim prior to the start of the takeoff roll
I'm not saying to trim the rudder prior to losing an engine.
but this idea of muscle lock and holding the rudder entirely with muscle, instead of getting some trim in there will make the transition from tracking the centerline visually to instrument flying a bit easier.
