§  87.265   Administrative communications.

   Domestic VHF aeronautical enroute stations authorized to use A9W
   emission on any frequency listed in § 87.263(a)(1) or § 87.263(a)(3)
   may transmit digital administrative communications on a secondary
   basis, in addition to the operational and control communications
   routinely permitted under § 87.261(a) above. Such secondary
   administrative communications must directly relate to the business of a
   participating aircraft operator in providing travel and transportation
   services to the flying public or to the travel, transportation or
   scheduling activities of the aircraft operator itself. Stations
   transmitting administrative communications must provide absolute
   priority for operational control and other safety communications by
   means of an automatic priority control system.
