Trimming problem in Wilco/PA A320 Merge

Post by sinsnowman »

I've been merging the PA planes with wilco panels for quite some time, but I'm unable to fully merge the A32x series because of a trimming problem, the aircraft requires a very high trim during landings in order to be able to flare. I've tried to search in your forum and other forums, but I don't seem to be able to find the solution. There's a solution saying that changing the following lines in the wilco aircraft.cfg

empty_weight_CG_position=0.000, 0.000, 0.000

to this
empty_weight_CG_position=0.63, 0.000, 0.000

I tried that but the trim is still out of normal during landings, any ideas?

ok you definatley dont have to change anything to merge them. Just give the PA airbus the wilco panel and thats it

Hello Propilot23k,

I am using as well the very nice PA Airbus merged with Wilco.

If you just assign the Wilco panel with the PA package, don't you get differences and/or errors (performances wise: ie fuel consumption, time, climb performances, takeoff roll, etc...) due to the differences between aircrafts??

Also, it seems that with PA airfiles the engine spool up time is quite long.

Can you tell me more about the merge you made?

Thanks a lot,

Alex

yea they are differences in how the air files perform but they arent that far off....Just give the PA airbus the wilco panel. dont change anything else. I think the only issue I had was with the flaps an I corrected it with a easy fix. if you want my aircraft cfg just inbox me your email address

Hello Propilot23k,

Thanks for the reply,

Actually I found the spooling time problem, it happen only if you mix the Wilco AIRCRAFT.CFG with the PA .AIR files.
I tried as you said but it look like the A320 with PA airfile is a very slow climber compare with the Wilco airfile.
Took the A320 for a short flight (about 200nm long, CI 80) at FL270 with 80% pax (@75kgs each + 25kgs luggage each, no cargo) and with 4.5T of fuel. So I wasn't very heavy.
So, to make a long story short, from FL200 to FL270 I was having only 300ft/min... Make the very same flight with stock Wilco airfiles and I got proper performances. I guess something's wrong somewhere...

Any idea why she is such a slow climber??

Cheers,

Alex

idk what you did because I surely don't ever have that problem. redownload the base for the a320 and merge the wilco panel.

I guess the empty_weight_CG_position mod DID solve the problem since I have similar problem on the original wilco with similar loading, the following entry in the aircraft.cfg
