Interpretation

On a trial basis, a surveillance-based reduced longitudinal separation minimum will be applied between qualified aircraft routing via PARAR. It applies only between aircraft that are RNP2/RNP4 compliant, have functional ADS‑B OUT, and meet RCP240. Pilots shall indicate RNP2/RNP4, CPDLC RCP240, and ADS‑B capability in the flight plan and should initiate an early CPDLC logon to Mumbai on address VABF.
