Catch 22, a wicked problem, depends on viewpoint, on which window we look through; there are rarely answers. e.g. is your glass half empty or half full?

A quibble with language (my window) is that the good advice to ‘look through’ the FD is a normal function implying a combination of attitude and FD, whereas in a stall we would wish pilots to ‘ignore’ the FD - focus on attitude, probably an even more difficult task than combination. How do you mentally reject an information display which in normal circumstances could be the dominant reference, but where with the effect of surprise and startle in an emergency the mind reverts to first learnt, most used, information.

This debatable point offers a potential alleviation for all parties to understand the issue and to debate the relative safety merits of situations. Thus a learning view, vice an examining pass/fail position, would highlight the importance of understanding the situation, particularly the precursors, what is important, and how to avoid the situation; and if unable, how to recover.

We are told with these types of problems to look at the bigger picture. So my half-full glass, emptied into a larger glass could be judged near empty - best bitter please. And if you are having this discussion in a bar you are clearly drinking with the wrong people.

Thus this ‘technical problem’ (actually philosophical and human) should be posed to management - the bigger picture; as a safety report, to the manufacturer and regulator for a wider view of policies, design, training, examining, mandates, and choice and use of procedures.
