Just as a note regarding real-world airport operations.
It's very rare for aircraft to use 9L for take off. Almost all operations on the 9's use 9L for arrivals and 9R for departures, and this is not usually switched during ops.
The default departure for aircraft on 9R would be from N11, with specific intersection departures at N10/N8 given to lighter/faster aircraft and for spacing. With that in mind, it is very common to see a row of A320/B737 lining up for N8 departure along taxiway A, with heavy aircraft using taxiway B for a full length.
Glad to see this airport in the game, and look forward to trying it soon.
Separate note for @Pedantic G - the taxiway onto 9R at the end is N11 not Y1.... that would be a helpful change too if FT can manage it.
