INTRODUCTION

This section supplements the following portion(s) of the AIP: AD

With effect from 2 February 2017, RNP10 operations on ATS Routes L507, P646, N895, L524 and L301 will be implemented as follows: In order to enhance ATS efficiency, capacity and air traffic safety over the Northern Bay of Bengal, operating procedures for RNP10 operation on ATS routes L507, P646, N895, L524 and L301 will be applied to westbound flights transiting Bangkok FIR. This AIRAC AIP Supplement provides details on the establishment and operating procedures of these ATS routes.

RNP10 NAVIGATION REQUIREMENT

ATC will apply 50 NM longitudinal separation minima between suitably equipped aircraft which are approved for RNP10 operations utilizing ADS-C/CPDLC or VHF communications under the following conditions:

50 NM longitudinal separation may be applied between RNP10 approved aircrafts with DCPC (VHF or CPDLC) operating on L507.

50 NM longitudinal separation may be applied between RNP10 approved aircrafts, equipped with serviceable ADS-C/CPDLC, operating on P646, N895, L524 and L301. The releasing ATC unit will ensure ADS-C/CPDLC serviceability before applying 50 NM longitudinal separation.

Controller-Pilot Data Link Communications (CPDLC) will be used as primary means of fulfilling Direct Controller-Pilot Communications (DCPC) requirement for providing 50 NM longitudinal separation between RNP10 aircraft on these ATS routes.

To ensure ADS-C/CPDLC serviceability before applying 50 NM longitudinal separation, pilot of westbound traffic intending to operate on P646, N895, L524 and L301 shall log on to Yangon CPDLC (VYYF) at least 50 NM before entering Yangon FIR and inform Bangkok ATC upon CPDLC is successfully established with VYYF.

For flights intend to land within Yangon FIR, ADS-C/CPDLC will not be required

Pilots are to advise ATC of any deterioration or failure of navigation system below the navigation requirements for RNP10 or unavailability of CPDLC. ATC shall then provide alternate separation and/or alternative routing.

Aircraft meeting RNP10 navigation requirements shall indicate /R in item 10a and indicate PBN/A1 in item 18 of the ICAO flight plan format.
