1. ## Arc Dme procedure

Hi at all, i would to know if there is one procedure to do with CDU to follow correctly one arc-dme procedure.

Thanks,

2. 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.

4. ## 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,

5. Ah yes you're absolutely right, overlooked that, sorry .

6. 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!

7. 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????
