IDENTIFICATION OF AIRCRAFT

  • To tell a Pilot his POSITION and LEVEL is BEING CHECKED on RADAR:

Pilot
BRUSSELS CONTROL, SAB141G, ON COURSE TO VEKIN DESCENDING TO FL180
ATC
SAB141G, BRUSSELS CONTROL, SQUAWK IDENT
Pilot
SQUAWK IDENT, SAB141G
ATC
SAB141G, IDENTIFIED
SAB141G, IDENTIFIED 10NM SOUTH OF VEKIN AT FL180 or
SAB141G, IDENTIFIED OVER VEKIN AT FL 180 or
SAB141G, IDENTIFIED ABEAM VEKIN PASSING FL190

Pilot
BRUSSELS CONTROL, OOJDH, AIRBORNE AT EBKT, CLIMBING TO 4000 feet
ATC
OOJDH, BRUSSELS CONTROL, IDENTIFIED OVER EBKT PASSING 2500 feet

NEVER say: RADAR IDENTIFIED !!!

  • Identified is used when the aircraft was NOT RADAR CONTROLLED by ATC before or was controlled by an ATC outside your FIR
  • Example: between EBLG TWR and Brussels ACC
  • To tell a Pilot his POSITION is STILL KNOWN on RADAR:

Pilot
BRUSSELS CONTROL, TUB9846, ON COURSE TO BUB FL 160
ATC
TUB9846, BRUSSELS CONTROL RADAR CONTACT
TUB9846, BRUSSELS CONTROL RADAR CONTACT 5nm EAST OF BUB
TUB9846, BRUSSELS CONTROL RADAR CONTACT OVER BUB
TUB9846, BRUSSELS CONTROL RADAR CONTACT ABEAM BUB

  • Radar contact is used when the aircraft was handed over by an ATC unit in the same FIR
  • Example: between EBBR APP and Brussels ACC
  • To tell a Pilot his POSITION and LEVEL is NOT KNOWN on RADAR:

Pilot
BRUSSELS CONTROL, OOHBB, ON COURSE TO SPI AT 1000 FEET
ATC
OOHBB, BRUSSELS CONTROL, SQUAWK IDENT
Pilot
SQUAWK IDENT, OOHBB
Pilot
OOHBB, NOT IDENTIFIED, BELOW RADAR COVER (or any other reason)

IVAO environment: Use IDENTIFIED for traffic coming from unicom or from a neighbouring FIR controller and RADAR CONTACT for traffic handed over from controller in the same FIR
