You cannot assign a certain runway twice. The assignments you made in the runways.txt file set both runways 4 and 22 to 'nil'. The following two assignments are no longer considered. I guess you should remove the lines with the 'nil' argument.
Hi Urs
I deleted the nil line and still no SIDS???
my runway text look like this now ....
EDDP 28 nil
EGSS 22 23
EGSS 4 5
LFSB 08 08
LFSB 26 26
i saved it, went in to a flight from stansted and went to departure and tried to assign a SID and there ghosted you cant choose?
this is getting really frustrating, any idea of what it could be, maybe you could try a flight from EGSS and see how to get around it
thanks you
