HiWherever I get my TP from, be it Planepath or Navdata, I get the error LEBL err: CLE unknown.I have used several versions of the LEBL file from various AIO collections and it happens on every one in both the 737 and the 747. Has anyone got one that works they would like to share?ThanksBill

The FMC error probably means navaid CLE is missing from the airac data you are using. I can't verify it where I am at now, but you can open the LEBL.txt file and see if the procedures are referencing NAVAID CLE or FIX CLE. If the reference is to a FIX then all fixes must be defined in the first section of the procedures file, but since you have multiple sources giving the same error I doubt this is the problem. If the reference is to a NAVAID then the sidstars files rely on airac data (files are downloaded from navdata.at). You didn't mention if you have current airac data, but it is important because these files (stored in the FMCWP subdirectory) provide all navaid, runway and airport location info required by the terminal procedures.Hope this helps.

Thanks for the reply Dan. In the end I started going through all 'back numbers' of the procedure at Navdata and found one written for airac 0313 which does not cause the problem of nothing at all showing but does cause a very minor problem where (presumably) a change in the magnetic deviation has altered the numbering of the runways. That is easily overcome.RegardsBill
