Post subject:  Altitude hold on FL 130

During my last flight the ATC didn't let me go to my designated FL which was 370. Instead of this it called me up to FL 130 and let me stuck there. That's the first time that this happened to me and I think also right after I upgraded to 3.7.1. Anything I did wrong?
Any help appriciated

It's likely that there is a problem with your flightplan. Please zip your log file and we'll have a look at it to see what the cause may be.

Looking at the log it would appear you were flying a little hap haphazardly. :shock: After ATC instructed you to climb to FL130 you climbed to around FL125 then descended to 115 then climbed again and went past FL130. You did receive a 'maintain FL130' from ATC but chose to ignore it and kept climbing. :o

Hi Dave,
you're right I struggled a bit with the CRJ from Aerosoft and its possibility to get / maintain a FL. Will try this weekend again and if the abnormality continuous I'll send you the logs files again.

Hi Dave,
actually this flight went a bit better, but unfortunate I still stuck on FL 130; stayed there for a while before I hade to got up to the FL (370) of my FP. have attached the logs.
Pls. tell me what I did wron this time

figured out what happened; my FO sets the ATC freq but not accurate enoght, so he mostly set the values left from the decimal correct but mostly the values on the right side are just set to ".00" and not e.g. .15
So I'm struggling with an different issue.

Oh right, that wouldn't help and I didn't spot that in the log... I'll take another look but thanks for letting me know.

forgot to mention this it happens on the crj 900 from aerosoft. I see it on the MCDU of the co pilot he's either dialing the correct value (e.g. 109.70) without the decimal sign which caused an invalid error or he's dialing e.g. 109.00 also without decimal sign which caused again an invalid error. And actually I donot know whether its the crj itself or pf3 or mce

I wouldn't be surprised if the problem is with the aircraft. The radio frequencies both Comm and Nav are divided into two. One dial sets the whole numbers and the other the fractions.
This is in fact already hard coded into the sim but developers sometimes like to do things their own way and this can lead to errors.
If the a/c developer lets the sim do it then the code is
Quote:
<Click Event="NAV1_RADIO_WHOLE_DEC" Repeat="Yes"/>
<Click Event="NAV1_RADIO_WHOLE_INC" Repeat="Yes"/>
Then the sim reads the numbers in three steps to divide it correctly into integer, tenths and hundredths like so
<Value>(A:NAV1 ACTIVE FREQUENCY,MHz) 100 * 1000 / 10 % flr</Value>
<Value>(A:NAV1 ACTIVE FREQUENCY,MHz) 100 * 100 / 10 % flr</Value>
<Value>(A:NAV1 ACTIVE FREQUENCY,MHz) 0.001 + 100 * 10 / 10 % flr</Value>
Note. This example is in XML which uses reverse Polish notation. Which is why nobody on the planet understands it!!
This would certainly not cause a problem with PF3 and perhaps not with MCE. As I don't have MCE I can't confirm how the developer reads frequencies.
