This very informative about the use of Wx radar gain. I've not heard it explained so, and not read it either, even in user's guides. Asked around in our training dept. EU based; puzzled looks. CB's can go high in Europe as well. Seems there's a lack of guidance out there.
Considering the unreliable/disagree airspeed; that's a gotcha as we usualy use the 2 out of 3 is correct rule. ln this case they were all different. Bring Gnd Spd into your scan; essential, and perhaps AF447 would have survived. Deciding that F/O's was correct, but I suspect there were some furrowed brows over that. Did the Capt's side give stick shaker?
