We got this one guys. Thanks all.
Hi PMDG,On my way to DAKAR (GOOY) out of Frankfurt, i replicated this issue. The cabin climb was reading zero from take off til i reach FL360. So, as Dr EMVAOS said he got this, can we get a fix or an explanation for this one please. It is very weird because i fly the NGX every single day on Ivao since realease date 04 August and i have more than 500H on, but i can't understand where this comes from. Furthermorei've flown the easy jet 700 yesterday and all went very well.....

It has to do with the pre-pressurisation of the cabin during take off trigger. On your GOOY flight you used considerable derate yes ?Fixed so don't worry.

Yes sir i was departing from edff (to GOOY) and used max engine power via the fmc. I was almost at the MTOW so ......yeah. It was not (CORRECTION HERE) a derate take offAnd i started with a YES, because i know it has something to do with pre-pessurisation(only know how to day it in french)

What you're describing is the opposite of a derated-thrust takeoff. Derating is when you use less than max engine power.For my part, I almost always use a TO-2 + assumed temp derate.

Is PMDG gonna fix this in the next SP or ? Because Ryan and Mr Vaos said they knew where this issue comes from. Because i'm having this issue on and on and on..... It seems that the cabin climb reads the correct value only when i use a normal take off config in the FMC. Using derate and the needle is stuck on the zero.
