5-1-2. ATC SURVEILLANCE SOURCE USE

Use approved ATC Surveillance Sources.

• REFERENCE
• FAA Order JO 7110.65, Para 5-2-13, Inoperative or Malfunctioning Interrogator.

1. Secondary radar may be used as the sole display source as follows:
   1. In Class A airspace.
   • REFERENCE
   • FAA Order JO 7110.65, Para 5-2-14, Failed Transponder in Class A Airspace.
   • 14 CFR Section 91.135, Operations in Class A Airspace.
   2. Outside Class A airspace, or where mix of Class A airspace/non-Class A airspace exists, only when:
      1. (a) Additional coverage is provided by secondary radar beyond that of the primary radar, or
      2. (b) The primary radar is temporarily unusable or out of service. Advise pilots when these conditions exist, or
         • PHRASEOLOGY
         • PRIMARY RADAR UNAVAILABLE (describe location). RADAR SERVICES AVAILABLE ON TRANSPONDER OR ADS-B EQUIPPED AIRCRAFT ONLY.
         • NOTE:
         • 1. Advisory may be omitted when provided on ATIS and pilot indicates having ATIS information.
         • 2. This provision is to authorize secondary radar only operations where there is no primary radar available and the condition is temporary.
      3. (c) A secondary radar system is the only source of radar data for the area of service. TERMINAL. Advise pilots when these conditions exist.

         NOTE: Advisory may be omitted when provided on ATIS or by other appropriate notice to pilots.

2. TERMINAL. Do not use secondary radar only to conduct surveillance (ASR) final approaches unless an emergency exists and the pilot concurs.
3. All procedures and requirements relating to ATC services using secondary radar targets apply to ATC services provided to targets derived from ADS-B and WAM.
4. Targets derived from ADS-B and WAM may be used for the provision of all terminal services when operating in STARS Fusion, STARS FMA, and STARS Multi-Sensor Mode, including those associated with any published instrument procedure annotated "radar required."

   NOTE: Targets derived from WAM cannot be used to provide 3NM separation in the EAS. 3NM targets are not derived from WAM within the EAS.
