As VATSIM is now introducing half-degree waypoints for Cross The Pond, I fiddled around a bit with the possibility to enter custom waypoints into the A310 FMS. I came across some issues, however, also after referring to the original flight crew operations manual of the A310 (very interesting read, by the way …):
Entering coordinate waypoints seems not to be working reliably, especially not in the N4512.3/E305.1 or similar formats. Only the ARINC 424 format seems to work, but also not in every case.
Entering custom en-route waypoints, e.g. SUGOL/10, does not place the new waypoint on the original course, but instead 10 nm somehow offset of SUGOL at an angle.
I tried to define new waypoints via the REF page, but I did not suceed in entering LAT/LONG, instead always get a format error.
Even worse, all flight deck screens black out when I try to look at a custom waypoint previously introduced via the flight plan page.
Am I doing something wrong here, or are these just limitations of the FMS system in the ini A310? Is there any other ‚proper‘ way to insert half-degree waypoints into the FMS, except from importing them e.g. with the SimBrief flight plan?
Thanks a lot for any help! I‘d really love to do Cross The Pond with the A310 this year!
