Sec. 87.307  Cooperative use of facilities.

    (a) The Commission will license only one flight test land station 
per airport, except as provided in paragraph (d) of this section.
    (b) Flight test land stations located at an airport are required to 
provide service without discrimination, on a cooperative maintenance 
basis, to anyone eligible for a flight test station license.

[[Page 227]]

    (c) When the licensee of a flight test land station intends to 
conduct flight tests at an area served by another flight test land 
station, which may result in interference, the licensees must coordinate 
their schedules in advance. If no agreement is reached, the Commission 
will determine the time division upon request by either licensee.
    (d) An application for an additional flight test land station at an 
airport where such a station is already authorized must be accompanied 
by a factual showing which must include the following:
    (1) Reasons why shared use of the currently licensed flight test 
land station is not possible; and
    (2) Results of coordination with the current licensee of the flight 
test station at the airport demonstrating that an additional station can 
be accommodated without significant degradation of the reliability of 
existing facilities.
