Unless otherwise determined by the Secretary of Transportation, or otherwise agreed to by the sponsor (county of Merced/Castle Airport) and the using agency, substantial use of an airport by government aircraft will be considered to exist when operations of such aircraft are in excess of those which, in the opinion of the Secretary, would unduly interfere with use of the landing areas by other authorized aircraft, or during any calendar month that:
- Five or more government aircraft are regularly based at the airport or on land adjacent thereto; or
- The total number of movements (counting each landing as a movement) of government aircraft is 300 or more, or the gross accumulative weight of government aircraft using the airport (the total movement of government aircraft multiplied by gross weights of such aircraft) is in excess of five million (5,000,000) pounds.
