For the T-38, the takeoff Refusal Speed is computed using a 3" reaction time, during which the aircraft continues to accelerate.
In other aircraft, the speed is based on starting the abort at that speed, with no reaction time.
I'd like to know what is done in other aircraft in the military. I'm not looking for "technique", just what is in your flight manual when it comes to the consideration that was used in creating your performance charts.
Bombers, trainers, fighters, heavies... let me know. Post it here or drop me a pm.
