The message about the jetways is correct, because GSX won't let you use a jetway that it already *knows* (because it asked SODE to pre-solve it without animating it) it won't reach a door for any reason.
While the FSX default animation might have resulted in visual bugs, like jetways sinking in the ground, or exploded, with SODE it's either perfect, or it won't even move, which we believe is far more realistic.
There might be many reasons why a jetway cannot solve, and are a combination of:
- The plane used
- The actual parking position, which includes both the position and even the heading.
