Class C airspace is 20 miles in diameter at most. How much time is required
for a typical piston single to transit that distance?


Four and a half hours. After that, he may run out of fuel. The pilot might be
able to hold out for six or seven, depending on tanks and power settings.

The pilot is not required to transit in a straight line. The controller is not
required to intercede if the pilot is circling inside the ring. The pilot is
not required to inform the controller (unless asked) of his routing. The
controller is not required to ask.

Pilot takes off, calls the controller and is told to remain clear. Pilot
circles the outer ring for four hours and fifteen minutes. Pilot calls again
and the controller responds with:

N1234 stand by.

Can he enter?

What if he landed and took off again sometime in those last four hours.
