Hi Everybody.

 

First post in the forum. Thanks for all the info and help here.

 

I tried to find the solution to the problem in this forum and google it, and found a link to FMC Custom Waypoint Entry Notes

(Home/Knowledge Base/PMDG General/FMC Custom Waypoint Entry Notes) , where it explains how to set a custom waypoint, (BTW, the PMDG 747 has a FMC Users Guide Manual that states the same)

 

I'm trying the first format, Alongtrack to comply with ATC (Radar Contact)  instruction to be at FL110 10NM before vor XYZ. XYZ is in the flight plan ( RC and NGX FMC).  When setting XYZ/-10 at  XYZ int the legs, the FMC states INVALID ENTRY. I tried putting the entry before and after XYZ  with same result. The distance between the waypoint before XYZ is greater than 10NM (45NM)

 

Place Bearing Distance works as well as Long/Lat. Did not try Course Intersection.

 

I loaded the same plan to the PMDG 747 and tried the Alongtrack and input to XYZ/-10 waypoint and IT WORKED. So it seems to be an NGX FMC issue or the format is incorrect or something I can't see

 

Config:

FSX SP2, W7

PMDG NGX SP1c

 

 

Thanks

For the along track waypoint, I believe you must copy the waypoint in question using the line select key next to it, and not manually type it in. You are correct in the format being xyz/-10, but I seem to remember that it doesn't work typing in "xyz" manually.

PRECISELY.!!!

Weird anyway that it doesn't accept keyboard...

 

Thanks Steven.
