The other subject which deserves discussion is whether to make a level acceleration or not where a relatively close-in obstacle is concerned.
For example, the emergency procedure off Geneva 23 requires a turn at 6.2D back to St Prex (which is more than a 180º turn).
Making a level acceleration (which we normally do) versus maintaining configuration and V2 - V2+10 to 6.2D and then making the turn at 15º of bank is not such a good idea. The traditional clean up method leaves you 500 feet lower in this case on my current type but nowhere does it tell you this in our (Swedish) RTOWs. (I have proved this in the sim).
I am told that the performance engineers have to make such an assumption when preparing RTOWs for runways with close-in obstacles.
Wouldn't it be nice if the theoriticians were to tell those of us who might have to put their wonderful ideas worked out in a nice warm office into practice on a dark and stormy night?
