Flex T/O & Speed Corrections
Hey folks,
Im on the A330, and when calculating our speeds for a Flex T/O and using the corrections tables, we only have to adjust the flex temp and not the speeds unless there is a WET factor, where we then reduce both speeds and flex temp. ie) for QNH corrections, we just subract from the Flex Temp and V1/v2/vr corrections arent necessary. This is also given the Airbus FCOM 2 manual.
Cant someone please explain why the speed corrections arent required for QNH, Packs on/off, etc, but they are for WET?
Thanks for the help,
Mac.
