Radar/ADS-B/MLAT based Horizontal Separation Minima in Indian Airspace

The following information on separation minima based on radar and/or ADS-B and/or MLAT systems shall be applied in addition to those given in Doc 4444 – PANS -ATM Chapter 8 to the aircraft operating in Indian airspace.

  • 5 NM horizontal separation up to 60 NM from radar head
  • 5 NM horizontal separation within 60 NM of ADS-B ground station when only ADS-B is used in non-radar environments
  • 10 NM horizontal separation beyond 60 NM from radar head
  • 10 NM horizontal separation beyond 60 NM of ADS-B ground station when only ADS-B is used in a non-radar environment
  • 3 NM from the radar head were specifically authorized

Where ADS-B and/or MLAT is/are used in combination with radar the horizontal separation minima applicable will be same as applicable to the separation based on radar.

Where MLAT is used alone the horizontal separation minima applicable will be as notified/prescribed before its implementation.
