§  87.525   Scope of service.

   Automatic weather observation stations (AWOS) and automatic surface
   observation stations (ASOS) must provide up-to-date weather information
   including the time of the latest weather sequence, altimeter setting,
   wind speed and direction, dew point, temperature, visibility and other
   pertinent data needed at airports having neither a full-time control
   tower nor a full-time FAA Flight Service Station. When a licensee has
   entered into an agreement with the FAA, an AWOS or an ASOS may also
   operate as an automatic terminal information station (ATIS) during the
   control tower's operating hours.
