They just assumed that DAKAR OCEANIC would get comms with the a/c at some stage of its transit through the DAKAR FIR.
Yes, I think so. Missing comms is initially, not that big a deal on the Pacific, Atlantic or Arctic. It is slowly changing as ADS and CPDLC installations grow.
But this is the sense of "normal" I was meaning to convey about comms; - when no scent of something wrong is sensed by anyone,
at that point.
