FCC License?

Maybe this has come up before, if so I appologize. I know that we
have had a thread on the need for an airport to have an FCC license.
This came up when one of the gliderports was fined for having an
expired license. This was useful, and timely, information for other
glider ports.

So there are now two followup questions;

- Does an FCC license for your airport cover the use of handhelds for
ground operations such as talking to the winch operator, the wing
runner to the guy logging flights on the "board", telling the guy on
the mower that someone is landing, etc? I would think that if the
communications are operationally necessary, the answer is no a license
is not required.

- Is an FCC license needed by myself when I am flying my glider? I
have been told no, but heard some conflicting information which was
more related to corporate pilots.

Can someone quote chapter and verse?

Thanks, John
