I suppose all us Skygods on here wouldnt be too troubled by a dodgy ASI
Nope, did it the other day ( see Senior Moment thread ) in my Turbulent, wasn't stalling in the climb, horizon looked to be in the right place but lowered the nose a touch to give a bit more margin, still climbing, set up rpm and attitude downwind, reduced power to normal descent power, normal attitude - no problem. Not a good scene tho' - won't bore you with the reasons why again.
Those who might not bother with a pitot cover - and there are plenty - might one day find a nice cosy spider in there - same effect, worth practising by covering the ASI one day, don't use very sticky tape tho' you might want to uncover it - quickly ! Have fun.
