  §  87.417   Scope of service.

   (a) Airport control tower stations (control towers) and control tower
   remote communications outlet stations (RCOs) must limit their
   communications to the necessities of safe and expeditious operations of
   aircraft operating on or in the vicinity of the airport. Control towers
   and RCOs provide air traffic control services to aircraft landing,
   taking off and taxing on the airport as well as aircraft transiting the
   airport traffic area. Additionally, control towers and RCOs can provide
   air traffic control services to vehicles operating on airport movement
   areas (see subpart L of this part). Control towers and RCOs must serve
   all aircraft without discrimination. An RCO must be remotely operated
   from a control tower or other FAA control facility located at a nearby

   (b) A control tower must maintain a continuous watch on the following
   frequencies during the hours of operation:

   121.500 MHz

   3023.0 kHz (Alaska only)

   5680.0 kHz (Alaska only)

   The Commission may exempt from these watch requirements the licensee of
   an airport control tower station if a satisfactory showing has been
   made that such an exemption will not adversely affect life and property
   in the air.
