Note : Mumansk has SELCAL capability. 7.1.11 The use of CPDLC is expected by Magadan (GDXB) when routed over RAMEL or ORVIT. Portions of Polar 3 (RAMEL, G491) are above 84.N and experience has shown that CPDLC coverage can be intermittent in that area. It seems solar activity may also impact your ability to log on to CPDLC. The standard for logging on is normally 15 to 45 minutes prior to the FIR/ entry point. It is important to remember however, 1 hour to 45 minutes out from RAMEL or ORVIT you are in Anchorage airspace and are under their control. If CPDLC contact made with Magadan while in Anchorage airspace, you cannot comply with any of their instructions until inside Magadan’s airspace. 7.1.12 Normally for flights on Polar 1 which Airindia is likely to operate there would be no need to contact Magadan. However for cases when aircraft have no contact with Murmansk they may contact Magadan and maintain necessary ATC communication with a request for relaying position reports/messages.
