  • 5-3-3. BEACON/ADS-B IDENTIFICATION METHODS

    When using only Mode 3/A radar beacon or ADS-B to identify a target, use one of the following methods:

    1. Request the pilot to activate the “IDENT” feature of the transponder/ADS-B and then observe the identification display.
      • PHRASEOLOGY
      • IDENT.
      • SQUAWK (code) AND IDENT.
    2. Request the pilot to change to a specific discrete or nondiscrete code, as appropriate, and then observe the target or code display change. If a code change is required in accordance with Section 2, Beacon/ADS-B Systems, of this chapter, use the codes specified therein.
    3. Request the pilot to change their transponder/ADS-B to “standby.” After you observe the target disappear for sufficient scans to assure that loss of target resulted from placing the transponder/ADS-B in “standby” position, request the pilot to return the transponder to normal operation and then observe the reappearance of the target.
      • PHRASEOLOGY
      • SQUAWK STANDBY,
      • then
      • SQUAWK NORMAL.
    4. EN ROUTE. An aircraft may be considered identified when the full data block is automatically associated with the target symbol of an aircraft that is squawking a discrete code assigned by the computer.

      NOTE: Paired LDBs in ERAM do not display a beacon code.

      • PHRASEOLOGY
      • SQUAWK (4 digit discrete code),
      • or, if aircraft’s altitude reporting capability is turned off,
      • SQUAWK (4 digit discrete code), SQUAWK ALTITUDE.

      NOTE: The AIM informs pilots to adjust Mode C transponders and ADS-B with altitude reporting capability activated unless deactivation is requested by ATC. “Squawk altitude” is included here to provide applicable phraseology.
