Airport managers can be morons. The one at EFD tried telling us we couldn't let helicopters land in the hanger area. Um...we pretty much can't stop them.
"Landing at your own risk, use caution for _____ (if applicable), wind. Report landing assured"
We can only tell them no for published prohibited areas/restricted areas and TFR's.
I had a heated discussion with the Airport manager, laughed at him, hung up on him.
I've had a few tail draggers request grass landings.
"Landing at your own risk, area west of runway one seven right is uncontrolled, use caution for ditch on right side of runway, wind."
