Actually more pertinent a waste of time climbing. Bit like bug cards in an ng. pointless, but all floating around somewhere (ryr for one, easy another. mcbride thread refers)) courtesy of some dinosaur that doesnt trust this new fangled palaver and got into a young company early doors .

Also You dont need an accuracy check of altis, if there are comparitors, every 10000feet. You may have done in a 70s tech bit of kit ,but not now.. The cfit you refer to is covered in setting the qnh sop or general situational awareness and so forth, not pointless babble from a bygone era. 10 checks are on of the few traditions that are timeless , the rest ..rote nonesense pitched as groundbreaking knowledge.
assuming a very low european winter qnh.If you checked your atli at 30.20 and 10 qfe. it still wont stop you flying into a hill, if the hill is at 2000 qnh and you are a knob.
These senior expat management are usualy peddling antiquated philosophies as their innovative ideas to gullable foreign masters and eager ,willing to eat sh1t ,widebody command hunters. (flak jacket on)
And thats about all i have to say. On behalf of Riojas finest . Good night
