I have to agree, Stik has it case pretty much sewn up. If you can't manage without it, you are unlikely to manage with it! One argument that might be levied against Stik's common sense approach is that the gaps between CAS are getting smaller and so concentrations getting bigger in those gaps. But if the PPL attrition rate continues, then we're in the clear again
Flik,
Reading my new multi book, the author makes a big point about doing in the air checks from memory (common sense) and in an unhurried way. The point he is making, is just because you are doing a FREDAI, there is no need to not to be looking outside.
WR,
I have to say I've seen a few aircraft wiggling their wings at they pass by. I might of half heartedly responded once, once I cottoned on that is. Most of the time I wondered "what's he doing?" I didn't really get it. I'll try being less grumpy next time
Also, perhaps training people not to fly at exact '000 feet altitudes may help? (I don't know because it needs a study of airprox and accident reports.)
I won't comment on my vertical zig-zags then
