Hi all! We have been experiencing an issue on site where threads have been missing the latest postings. The platform host Vanilla are working on this issue. A workaround that has been used by some is to navigate back from 1 to 10+ pages to re-sync the thread and this will then show the latest posts. Thanks, Mike.

    What is the reason for the various DMEs that are dotted around the country, e.g. GTG, WTP, MCM? They are in remote areas and from what I can make out seem to be unlinked to any SIDs, STARs, etc. If they were VORDMEs it would make sense (to me, anyway).

    Thanks.

    They are extra DME stations to aid enroute RNAV navigation. Non GPS positions are preferably determined as DME/DME fixes without the need for a VOR station.

    There was a thread a while back I think...!
