Using flex temperature on contaminated runways
Hi,
A simple question: why is using flex temperature on contaminated runways not allowed?
Using flex temperature still uses the Vmcg for the full rated thrust, so it's not that you would lose control is it?
With a contaminated runway you want to get of the runway ASAP, but why is a derate allowed then?
I've searched the forum for similar questions, but none gave me a definite answer.
Thanks!
