hmmmm...
hi xsbank...
I do not fully agree with you in all points:
first of all - there have been a number of incididents with CRJ200s and 850s ( or 604s.. with simular wing) related to deicing - and yes pilots must keep the wing clean as to the book - 100% correct.
but:
your post sounds like all aircrafts react the same way on a contaminated wing... - I guess it is not true, that all wings are so critical to ice on surface as the CL65 ? e.g. A300 AFM allows a few mm/layer of ice on the upper wing surface for t/o... Some wings will "forgive more, some less pilotīs mistakes"
but of course, i am neither an aerodynamics engineer nor an aircraft wing designer, just a pilot wo wants to meet his family after duty.
safe winter ops to all
