    Hi,

    as far as I know there is no special "arc DME" function within the CDU, just like in the real plane (at least in the 737).

    But you can easyly "build" an arc/DME procedure by creating your own bearing/distance waypoints (for example every 10° along the path of the arc) or put a disrance ring around your destination airport (by using the "FIX" function of the CDU) and follow this ring with HDG.

    The first technique is also mentioned in Mike Ray´s 737 Checkride Manual. I did this several times for practice, and it works perfectly.

    No need for HDG, once programmed or built, LNAV (and even VNAV) will do.

    he's correct ...

    to JWS: Imho, Stefanloss mentioned two different methods.

    One creates waypoints and is flyable by LNAV, the other merely draws a circle around a fix on the ND, and you need to fly along its circumference, be it hand-flying or executing segments with HDG sel.

    Cheers,
    Happy landings and always three greens !!

    Well, to make things even more confusing, you could even build your arc and then hand-fly along it.

    Sorry, couldn´t resist! Have a nice flight everyone!

    A lot less complicated procedure would be to just tune the DME and fly it by hand.

    Say again... just entering ".arc180270/010SPL" in the scratchpad and then somewhere in the LEGS page????
