Hello,I've been flying yesterday in the Birmingham area and got a strange error message on my FMC : "EGBB err : CPT53 unknown."This arrived when in the DEP/ARR page I press the DEP LSK button to select Birmingham as departure airport and want ot select a runway.I have loaded the last AIRAC data 0310 at navdata.at so theremaybe is something wrong with the last airac cycle of Richard STEFAN.Has anyone had this already ?RegardsPhil777

Hello Phil The SID/STARS file is using CPT53, which I dont think is in the last Airac.I have done EGBB in more detail, you can download the file from here http://homepage.ntlworld.com/simon.butler2...usefulfiles.htm and pop it into the PMDG SID/STARS folder.Simon

Thank you very much !I hadn't thought of the SID/STARS.I will try that out.RegardsPhil
