I'm never sure whether to download the SID/STAR packages from the PMDG website (Terry Yingling), or from the Navdata.at website???James Stevensonhttp://www.virtualaviation.co.uk

I am not sure what files Richard is providing (who makes them etc) but do know Terry is the PMDG SID & STAR master ;-). Terry has been a tremendous help with procedure files for this aircraft so I know his are top notch and he is constantly updating them and has worked closly to the team to produce very accurate procedures.

Most navdata.at procedures are more detailled and just made by people like you and me. I made the file for EHAM with another guy for example. :D With all respect, a lot of sidstars files of Terry are incomplete because they are derived from a military database.I suggest you to FIRST install the sidstar database of terry, and after that download the AIO file from navdata and overwrite all existing files in the folder.Good luck
