Section 5. Services NOTAMs


FIG 5-5-1


A graphic depicting the structure of a services NOTAM.


  1. Technical Operations personnel must ensure the origination of NOTAM D concerning the malfunction or degradation of FAA maintained systems and/or equipment.
  2. When notified, Technical Operations and Air Traffic personnel must ensure the origination of NOTAM D concerning changes to air traffic services and capabilities, for which they are responsible.
  3. Services provided by air traffic control (such as surveillance approaches, practice instrument approaches, practice low approaches) do not meet NOTAM criteria as a standalone condition.
  1. The party that issues the NOTAM is responsible for formatting the information correctly.
  2. Originate a NOTAM for conditions pertaining to the following conditions:
  1. Commissioning, decommissioning, or outage of TWRs, APPs, RAPCONs, FSSs, and ARTCCs that are part of the NAS.
  2. Automatic Terminal Information Service (ATIS).
  3. Automatic Flight Information Service.
  4. Automated Universal Communication (AUNICOM). AUNICOMs have portions that are automatically broadcast along with the voice recordings. When these functions are unserviceable or not available, issue a NOTAM.

Disseminate the following conditions as NOTAMs:

  1. Change in the hours of operation of an air traffic control facility or service. Tower hours of operation use the airport as the location identifier; for approach controls, since they cover a larger area, use the associated ARTCC(s). Approach controls located within multiple ARTCC airspace must have a separate NOTAM for each ARTCC. When needed, add which class of services is not available and whom to contact. Spell out facility names when used in the body of the NOTAM.
  2. Establishment of a temporary air traffic control tower. Specify the frequency(ies) to be used and, if necessary, the type of service provided with each frequency.
  3. At times, air traffic facilities temporarily extend their hours of operation. When this occurs, substitute “OPN” as the condition and include, if requested, the available services “CLASS X SERVICE AVBL” as shown in the examples.
  4. Total failure of an air traffic facility (for example, loss of communications, NAVAID monitoring, etc.). Provide the class of service that are not available; the class of services to expect, and, if needed, who to contact for services.
  1. Air Route Traffic Control Centers (ARTCC).
  2. Approach control.
  3. Flight service stations. FSS covering a large Flight Plan Area use the ARTCC as the location identifier; for FSS with a small Flight Plan Area use the airport as the location identifier. Flight Plan Areas located within multiple ARTCC airspace must have a separate NOTAM for each ARTCC.
  1. Covering a large Flight Plan area
  2. Covering a small Flight Plan area of 5 NM or less.
  3. Flight Plan area covering 2 or more centers
  1. Air traffic control towers.
  1. Traffic Management Program Alerts.
  1. When requested by the associated arrival ARTCC TMU, issue an alerting NOTAM for each airport where an arrival/departure reservation is required. NOTAMs should be in the self-canceling format whenever possible.
  2. When a flow control message (for example, arrival delays, ground stops, ground delays, airborne holding, etc.) is received from the Air Traffic Control System Command Center (ATCSCC), the tie-in FSS for the affected airport(s) must issue a NOTAM(s) in the self-canceling format.
  1. Technical Operations personnel, responsible for system monitoring, must ensure the origination of NOTAMs on the Federal Automated Weather Observation System (AWOS) as follows:
  1. When malfunctions or discrepancies are identified, they must be verified by any of the following methods:
  1. A certified weather observer, airport manager, or fixed base operator at the observation site.
  2. Reports regarding a given observation by two pilots within 2 miles of the airport prior to the observation.
  3. Technical operations personnel.


For non-federal automated weather systems, see paragraph 1-3-6, Non-Federal Facilities.

  1. When verified, issue a NOTAM and notify the responsible technical operations office of the discrepancy, unless they reported the outage. If notified of system failure or other irregularity by other than a technical operations office that cannot be verified by the methods given above, forward the information to technical operations office for resolution. Accept NOTAM cancellation information only from the responsible technical operations office.
  1. Accept NOTAM information on Automated Surface Observing System (ASOS) only from the NWS Weather Forecast Office. Either the person on duty, Meteorologist in Charge, or Lead Forecaster, at the NWS Weather Forecast Office is responsible for requesting NOTAMs to be issued and cancelled regarding ASOS system malfunctions and return to service. When malfunctions or discrepancies of an ASOS system are reported to a facility, they are reported to the NWS Weather Forecast Office.
  2. Disseminate only the following conditions as NOTAMs for AWOS and ASOS:
  1. Total system failure (which includes date-time code failures).
  2. The entire ASOS or AWOS observation is missing and no backup observation is available for long-line dissemination.
  3. The altimeter setting is missing and is not backed-up.
  4. The date/time group is erroneous and has not been corrected.
  5. Unreliable (intermittent) or inaccurate (erroneous) elements.


Unreliable or inaccurate visibility, temperature, and dew point will affect present weather information type and intensity reporting (i.e., rain, snow) within the system and must be included in the NOTAM.

  1. Commissioning or decommissioning of weather reporting. When commissioning an automated system that has a frequency/telephone number, include that information in the NOTAM. When decommissioning an automated system, unserviceable (U/S) with a PERM validity end date must be stated as the condition.
  2. The broadcast frequency of the automated weather system is inoperative, or has returned to service.


When reporting a failure or unavailability of weather reporting, do not specify the system nomenclature.

  1. Juneau Airport Wind Service is a wind warning system which provides turbulence alerts based on real-time wind information from anemometers and wind profilers around hazardous terrain.

Technical Operations personnel must ensure the origination of NOTAM D concerning microburst/windshear detection systems, such as low-level windshear alert system, Terminal Doppler Weather Radar and weather system processor.


The Technical Operations personnel must ensure the origination of NOTAM D concerning radar outages of 30 minutes or more. List the service restrictions with reference to the nearest NAVAID.

  1. Radar services for terminal facilities are described using the following terminology. Location identifiers used for the issuance of NOTAMs for terminal facilities must be the airport identifier.

Types of Radar

(secondary surveillance radar)

(surface movement radar)

(terminal area surveillance radar)

(ground control approach)

No contraction

  1. The contraction phrase “RADAR SER” must not be used. When describing the radar service, do not use the model number.
