At KDEN almost all aircraft at stands at concourse b and c are supposed to push to the end of the yellow line at the stand. This enables multiple aircraft at stands next to eachother to push at the same time in real life i believe. You are not supposed to start your engines until you have stopped at the end of the stand line. Also the taxi lanes closest to the terminals are not to be used by aircraft larger than the 767 and dc10/md11.
Also the apron taxilanes do have a standard directionality
Here is the diagram (cyan is for aircraft taxiing west, green is for aircraft taxiing east):
That makes sense. One thing I can say is that the engine start part isn’t true for all airlines. At least, when I fly SW out of Denver, the engines start after about 3 seconds into pushback.
Also, that sort of pushback position is actually super common at airports around the US. Not all of them, but many that have straight pushbacks won’t turn the aircraft during pushback
Sometimes you can find info online, or if you fly out of an airport long enough you can observe things being done a certain way every time. Or you have connections to ground workers. There are several that work at different airports around the world who are active here on the forum!
I only know these procedures from watching it happen irl multpile times. If you look at KORD on satellite imagery they also have something similar at the b and c gates. You will notice a Y shaped pattern at the end of the stands, those are also push and start positions
I’ve actually experienced taxi directions for CS and BN (also BS and AN) are the opposite of what you’ve shown. Or simply put, I’ve always seen the southern taxiway do ops towards the west, and the northern taxiway towards the east.
(dont judge me)
