Thing has mentioned IMC. This mention, in conjunction with another newer thread (where this comment does not belong), in which there has been speculation about a loss of control after entering IMC, seems to be a parallel situation to spins in some ways.
It seems normal and appropriate that all pilots should be taught some basic instrument flying skills, so they have a chance of extracting themselves upright from careless entry into IMC. Is teaching avoidance of IMC not working? If not, teaching managing those conditions just enough to get back out safely is obviously vital.
How would careless spin entry be any different? If teaching avoidance of IMC is not working, how would teaching avoidance of spins work?
