>>..."d: AXY8243 dial FL150"
Any commercial pilots out there? I'm trying to wrap my head around this. Is it a hand-off to another frequency ("dial") or a direction to change altitude ("FL150", "FL80"). If it is 'flight level' I would hazard a guess that if they're using flight levels they're not planning on descending - but that assumes the Russian aviation does a similar transition between local altimiter and standard pressure.
