Until I learned how to land the airplane in a crosswind with wings level and on the centerline....and until I could project the required level of comfort through demonstrated skill....and not by self proclamation...they were right to be careful
After so many many years in command, I am still not able to have my wings perfectly level in strong crosswind landings. I get on the centreline about 98% of the time, but wings level...er, maybe 50% of the time?
I think a lot of pilots have a really unbelievable high opinion of the capabilities but during my years of training and checking, I have seen all sort of stuff ups by the so called very best. Oh, the urban myths an legends we have to put up with...............sigh!
