Hi, I'm new here. I was searching and reading some thread about usage of packs-off takeoff in this forum, seems like most agree that a packs-off takeoff will increase the performance capability so as to carry more weight, even in the Flex mode.
I was wondering if I could've been taking off underpowered in a case like this:
TOW: 65 t
RTOW Chart saying:
Flex 60 would lift 65,5 t
Flex 65 would lift 64.7 t
Then Packs Off Correction saying +800 kgs
With that data then I elected to use Flex 65 with packs off. In hope the plane will have enough performance to carry 64.700+800= 65.500kgs
Is that correct? As I recalled from the Normal OPS, Airbus stated a packs-off takeoff will increase performance in a TOGA takeoff, and for Flex, it will reduce EGT. Which as I get it, that there will be no weight correction for Flex+Packs off
Any idea guys?
