What would be awesome is to have either one or two waypoints for where the pushback truck push the aircraft, what happen the most often in real life is the pushback truck push the aircraft and then turn to align him on the taxiway, the only way to have a somewhat realistic (visually) pushback is the push the aircraft further from the taxiway so that he don’t immediately do a 90° turn, which isn’t visually appealing…
Like this :
Having possibility 3 or 4 would be even better !
Also there are two time limitation, first the aircraft should wait that the pushback truck cleared the taxiway before being able to taxi.
And a countdown from where the pushback start should limit the minimum time before an aircraft can taxi, this time being based on the number of engines, as engines are started during the pushback operation most of the time.
Depending on how long the pushback path is, most two engines aircraft have them started before the end of the pushback as seen here :
But for some 4 engines aircraft, this is another story as they start two engine at once.
Same for those 3 engines like the DC10/MD11, but there are no spinner on the middle/top engine so a video wouldn’t be helpful here.
