I also only saw 2 orange lines for the park me!
I'm not sure to understand what you mean: if you are refering to the old-style optical alignement system in use at Terminal E, that's how is supposd to look like, it's not a "smart" system, it's just a fixed panel that gives lateral guidance using parallax effects. We put it there, because they are there in real life but, if you want to use a "real" working Docking system, you should go at Terminal A, C and D, where the digital SafeDock is installed.
I also tried it with a default 747, same results!
This is what I get with e default 747, it's not *perfect* alignment but it's good enough. Note that, the jetway system is handled by FSX itself, we only model the jetway but, what FSX does to reach the door, it does it on its own, even the default jetways have lots of issues at default airports, like wheels going into the ground with smaller airplanes, etc. so, it's the system that is probably not 100% solid.
