What i have seen is the creeping acceptance of instructors flying and climbing through cloud to go vmc on top to conduct an exercise. We have all done it. Been doing it for 30 years, trying to earn a crust.
This gives the student the impression that flying in cloud is ok, and they are some how protected from disaster because they are with a flying instructor.
My first instructor was an ex Battle of Britain guy, he said you stay clear of cloud, if you enter you will fail your test. But if you do enter cloud then climb.
Later on a PPL took his advice, flew into a snow storm, then climbed to nearly 10k feet. Was radar vectored back into Brum.
And another guy left out flying club, not our member, with me saying the next time you hear about him, will be the news. I don't want to look at his aircraft as i don't want to be at a coroners court explaining what i saw.
Was the next day.
