  • 4-7-10. APPROACH INFORMATION

    interpretation 7
    1. Both en route and terminal approach control sectors must provide current approach information to aircraft destined to airports for which they provide approach control services. This information must be provided on initial contact or as soon as possible thereafter. Approach information contained in the ATIS broadcast may be omitted if the pilot states the appropriate ATIS code. For pilots destined to an airport without ATIS, items 3-5 below may be omitted after the pilot advises receipt of the automated weather; otherwise, issue approach information by including the following:
      1. Approach clearance or type approach to be expected if two or more approaches are published and the clearance limit does not indicate which will be used.
      2. Runway if different from that to which the instrument approach is made.
      3. Surface wind.
      4. Ceiling and visibility if the reported ceiling at the airport of intended landing is below 1,000 feet or below the highest circling minimum, whichever is greater, or the visibility is less than 3 miles.
      5. Altimeter setting for the airport of intended landing.
    2. Upon pilot request, controllers must inform pilots of the frequency where automated weather data may be obtained and, if appropriate, that airport weather is not available.
      • PHRASEOLOGY
      • (Airport) AWOS/ASOS WEATHER AVAILABLE ON (frequency).
      1. ASOS/AWOS must be set to provide one minute weather at uncontrolled airports that are without ground-to-air weather broadcast capability by a CWO, NWS or FSS observer.
      2. Controllers will consider the long-line disseminated weather from an automated weather system at an uncontrolled airport as trend information only and must rely on the pilot for the current weather information for that airport.
      3. Controllers must issue the last long-line disseminated weather to the pilot if the pilot is unable to receive the ASOS/AWOS broadcast.

      NOTE: Aircraft destined to uncontrolled airports, which have automated weather data with broadcast capability, should monitor the ASOS/AWOS frequency to ascertain the current weather at the airport. The pilot should advise the controller when he/she has received the broadcast weather and state his/her intentions.

    3. Issue any known changes classified as special weather observations as soon as possible. Special weather observations need not be issued after they are included in the ATIS broadcast and the pilot states the appropriate ATIS code.
    4. Advise pilots when the ILS on the runway in use is not operational if that ILS is on the same frequency as an operational ILS serving another runway.
      • EXAMPLE
      • “Expect visual approach runway two five right, runway two five right I-L-S not operational.”
    5. TERMINAL: If multiple runway transitions are depicted on a STAR procedure, advise pilots of the runway assignment on initial contact or as soon as possible thereafter.
