Hi all,
Having often the pushback issue, from Prepar3D v4 (Academic, lastest version 4.0.28), airport is Düsseldorf EDDL (JustSim), stand C02, airliner is PMDG 777-300ER (lastest version) Air France SkyTeam livery.
Having "Departure clearance requested" message, then a menu for provider/company choice for pushback (eg Lufthansa), selecting default, but no towing vehicule comes in front of airplane for pushback.
Also I've seen the PMDG 777 aren't is "List of supported airplanes in GSX", here
http://www.fsdreamteam.com/forum/index.php/topic,5481.0.html - but February 2012... assuming it's not really recent!
Sometimes the pushback works fine, but it's rare, too rare, unfortunately. Other ground services such boarding, catering or follow me vehicle is working fine in general. Same for jetway (stand C02) for left entry 2 (since lastest EDDL update from JustSim together with SODE v1.5.3 designed for x64).
Doing a "Couatl reset" doesn't solve this issue, however. Also at destination airport (any addon or stock) often the deboarding (cargo) works, but the vehicles stay (don't quit away airplane).
Assuming they're many bugs, but understanding is complicated for development.
Thanks in advance.
