Mad (Flt) Scientist, hi there.
Had a discussion the other day with a guy regarding the subject of VMCG in conjunction with derated thrust. I mean derated thrust allows you to reduce the VMCG consequently increasing the MTOW and so on. Here is the thing though SOP says that if using flaps 2 or 3 on A346 for derated take off don't use TOGA unless above F speed. Any idea whats that all about?
Cheers.
