I am actually not at my GAAP tower at the moment, but will be soon. My understanding (which may change once I am back there) is that the six aircraft includes inbound and outbound aircraft. I think that essentially limits us to the number of aircraft in the CTR. I could be wrong, there may be other current GAAP controllers that can confirm that for us.
We do have the ability to go +1 on one frequency so we can have 13 aircraft in total.
