Hello,
I tried to alter the flightlevel of a fix in the FMS, but it did not react to the input.
It was on a flight to Vienna, there is the fix NERDU with an altitude constraint between 6000 and FL17000. The FMS showed 6000, i wanted to change in 12000 / FL120. I used the term "/12000" as well as "/FL120". I could not change it. There was no error message, the input was simply not accepted.
The aircraft passed this fix at the high constraint border FL170.
Am I missing something, did I do something wrong?
Thanks in advance and best regards!
