Since installing B50.0 I have an issue when flying with STD pressure on a FL. I recognized it when flying online. Controllers tell me I´m on a wrong altitude and ask me, if I´m flying with local QNH. I have definitively turned "STD" and the correct FL in the FCU as well as in the PFD. My son, who also is controller in VATSIM network, checked it in Euroscope. We can reproduce it in every flight. I crosschecked it with the Jahn/Visser DC-3, and there all is o.k. It must be an issue of A320 FMGS to give a wrong altitude to the simulator. I have it in Prepare3Dv3.4 same as in Prepare3Dv4.2. Flying above transition the altitude for the FL (not the altitude for QNH) becomes correct, when I turn in the local QNH. This changes, when I am still below transition altitude or when I descend below transition level. Here the altitude with local QNH becomes correct.
Strange! Seems my A320 FMGS automatically changes to the FL above transition altitude while the local QNH is tuned in and therefore the altitude gets wrong when I turn to STD pressure. Turning to QNH 1013 leads to same result.
Anyone with same problem (caution: you will only recognize that when flying online!)? JL, do you have an idea?
Happy easter to all!
Hi!
The issue is described in the FMGS Installation Guide on page 44:
Setting the "Altimeter Temperature Effect" option to "no" should solve the problem.Quote:
Altimeter Temperature Effect : Basically, FS and P3D do not simulate an important
phenomenon : the effect of temperature on the altitude displayed on the altimeter. If it is
warmer than the ISA atmosphere, the altimeter underestimates the altitude; if it is colder,
he overestimates altitude.
The default "Altimeter Temperature Effect" option ("yes") takes this effect into account.
However, for those who fly online (IVAO, ...) the altitude of the aircraft will not be that
expected by the controller or other aircrafts ... The "Altimeter Temperature effect" option
allows you to disable this function by replacing “yes” by “no”.
Regards and happy Easter,
Isak
THX a lot, that did the job. RTFM...
Finally installed 50.0 yesterday and got the same „issue“ with the engine not starting (going to auto-crank)... I do not understand this behavior.
Is there an explanation for it?
But overall, thanks for your effort, JL!
Cheers,
Micha
Hi Fred,
Installation Guide is in the package...
You've surely installed it, while installing B50.
It's the same for all JeeHell versions, all the official manuals can be found in your folder C:/A320FMGS... :
>>> Installation Guide,
>>> User Guide,
>>> Advanced User Guide.
"EN" for English version, "FR" for French version...
Regards,
Michel
One thing more :
If you want to read it before any installation, you just have to :
>>> run the installer (as an administrator),
>>> uncheck all the modules during installation : You will get all the manuals.
>>> Paste them in another folder.
>>> Then run the uninstaller "unins000.exe".
Regards,
Michel
...and of course, the manuals are updated with every new JeeHell version...
