Cleared for Takeoff
When an airport accepts Federal Funds they have to sign off on "Grant Assurances" that essentially say the Federal Government controls the airport. A sponsor (Airport Owner) cannot make up rules or laws that will be contrary to Federal Law or operating practices.
But as others have pointed out, how is this "rule" contrary to Federal Law? Indeed, how is it any different than an local airport authority "rule" that says "no take-offs or landings 11pm to 7am" or something like "no touch and goes?"
So, what's their recourse if you violate their local rule? Can you be denied access to a public airport for not playing by the local rules? Is there any FAR that wraps up local rules into something that is actionable against your certificate?
