Let’s say you are on expert and you plan to flight circuits. You are first in line, and you request takeoff to remain in the pattern. ATC then says you are cleared for takeoff but they are “unable pattern work”. What do you do in that situation? You can’t turn around, because there’s no room to. You can’t just do it anyway, or you’ll get your ass ghosted to next Saturday. You can’t sit there and file a flightplan, because if you do, you’ll be holding back a line. Really, the only solution I see is to leave.
What are you supposed to do?
