Small GA aircraft with no weather radar and no deice and no turbo are
marginal for flying in IMC. Trouble with IMC, not only can't you see
(manageable), there is all this BAD WEATHER. Just because you have an
IFR rating and an IFR airplane doesn't mean you can fly in THAT
weather. There are plenty of IFR conditions that are not safely flyable
by small GA aircraft.
