I do have a question that falls under this topic though. How often are people doing reduced thrust take offs(De-rated) in order to increase MTOW due to Vmca/cg?
We do it everytime the runway is contaminated.
bflyer, when asking a question, its always better to state the aircraft type. On the B727, use of reduced thrust isnt permitted with improved climb.
Now if you were talking about the B777, there is nothing wrong with producing a "optimum" takeoff data chart which would include improved climb and then applying reduced thrust.
Mutt.
