Manwell, it may have been
me who taught YOU!
Oh and I
do use the rudders
although it does seem to be something many of the younger guys DON'T do.
Unfortunately I don't qualify for the latter any more.
Pity some of you PPL'ers don't fully comprehend "rate of closure"
vs the lack of depth/distance perception at altitude, even at night and excluding the daytime glare factor.
Even when advised by ATC of the position and distance of a converging aircraft, AND with the benefit of TCAS (assuming you know what TCAS is), 7 times out of 10
neither of the 2 pilots will locate it, and in the instances when they do, it's usually within 10 miles (at a closure rate of 900kts+).
As is often also the case, 1 pilot will be able to sight the aircraft, but the other cannot, due to the above mentioned factors.
