Zazu Posted March 22, 2013 Report Share Posted March 22, 2013 It's that time of year again, recurrent exams. Every year the same question is asked regarding a clogged air filter in falling snow. Every year the answer is the same. Yet I would like to know why I can't open the doors in blowing snow? To put it in context, I have flown a 350 D quite often in heavy snow, within visibility limits, with no filter and have never run into a problem. Both with the 101, and 600 engines. The only things I can come up with is: 1) There was associated laminar ice build up along the fuselage of the a/c during testing that could fly into the by-pass orifices during testing. 2)That the orifice of the by-pass system is such that it creates a venturi and would create ice out of the heavy snow fall to such an effect as to cause engine failure. Basically, what I would like to know is if my filter clogs in flight in snow, "What do I have to lose by opening the bypass doors"? Btw...anybody actually had a clogged filter in snow that was clean prior to flight? Thanks for your input. Quote Link to comment Share on other sites More sharing options...
