[ATC] - SXM A stands

:hammer_and_wrench: How would it work in the game?
Now that we have categories for aircraft, SXM has two stands (C1/6) that can easily accommodate A planes.

:balance_scale: Why is this a good idea?
This will enhance stand options for A planes and add at least two new stands officially on the C apron. It will be very beneficial especially with all the A planes flying into SXM.
