A32nx: Thrust seems low[BUG]

[PGTV9]

Mod Version

1.8.3

Describe the bug

Aircraft has a really hard time climbing. I believe thrust is too low.

To Reproduce


1.Go to FL300 and try to climb FL380 at V/S of 1000 engines do not have enough power to maintain speed
2.
3.

Just as a sanity check for incorrect configuration of auto-throttle/auto-pilot, the throttle is in a non-reduced thrust position (eg at CLIMB, FLEX/MCT or TOGA)?

Had this issue while flying last night [UTC:1900] on live weather from KDEN - KLAS. After FL250 the aircraft struggles to climb above 900fpm, and after FL300 the V/S was almost down to 600fpm. Throttles were on CL for the whole flight, double and triple checked my throttle positions.
Wasn't sure if this was a "corrected" version, but the thrust feels way less that the master files a week ago
EDIT: it was also the first flight I have done with the mod with the flex temp inputted into the MCDU, so not sure if it's related to that

Can confirm as well. Higher altitudes it really struggles, now.

I feel it this way too when taking off from SEQM (8000 feet rwy elevation). Setting up a flexmax of 64 like the calculator tells me. Initial climb is way too slow, struggling to stay at 160/170. I have to decrease flaps way early to gain some speed.

Hi,
what was the gross weight of the aircraft?
60836kg? (indication bug, doesn't change with fuel burn)
Is the GW calculated correctly within the sim (so the GW on SD is just a fixed text for now)?
What climb speed? Around .77/78 or .80?

Flex 64 and 8000ft elevation is also a rather demanding combination. At what OAT? Although 60t is quite a light weight...
@aboodilatif
Flex is for takeoff only, shouldn't alter the inflight performance in any way

And FYI:
Even the 747 (-400 and - 8) IRL had troubles departing from MEX (~7000ft elevation).
High altitude and high temperature (high DA) is just not helpful for climb performance.
A few degrees temp more or a few knots less headwind and the MATOW was reduced by a few tons(!)

Realmente Impuxo muito baixo acima de FL300 ele quase para!!!

Don't have the exact GW, but fuel was about 12000 LBS and the payload about 40000 LBS, so not too heavy.
Flex calculations were done via http://wabpro.cz/A320/ with flaps 1.

when did this issue start happening?

is it a problem in the vanilla unmodded game?

Pode ser que o problema seja do Jogo mesmo, não sei...começou faz pouco tempo, talvez depois da atualização...
