Issues around de-ice on a 182

Andrew Gideon wrote in message gonline.com...

Is it the longer duration of the Mooney's [certified] TKS? Is it really
safe to continue in icing just because the TKS is known-ice certified, or
isn't that still asking for trouble?

One difference is that the Mooney has a longer TKS fluid duration.

Another difference is that a known-ice certified TKS system will have
redundant TKS pumps.

Another difference is that a known-ice certified airplane has been
flight tested in ice, including the engine induction and fuel venting
systems.

It is not a good idea to remain in icing conditions intentionally but
let me give an example when I might do so. If I were flying a booted
known-ice airplane on top of an overcast, when ATC started vectoring
me for an approach I would request a "slam dunk" type approach, e.g.
perhaps a localizer instead of an ILS. If I were flying a TKS
known-ice airplane and the TKS fluid were preventing all ice
accumulation on the airfoils, I might instead choose the more
stabilized ILS approach.
