What are the rules regarding known icing and experimentals.

I believe on certified airplanes a system must be approved
for "known icing" before a flight may be launched into
"forcast icing" conditions.
Approval is different than having the equipment. That is
you can install all or part of a known icing package on an
airframe under a field approval and still not get "known icing"
approval because the airfame is a different model year.

Having the equipment is a great "safety of flight" issue as
a "unforcast icing" encounter might be survivable.

Are the rules different for experimentals? Approved icing tests
would be very expensive.Are we allowed to self approve
for the purpose of expermentation? How about if I am experimenting
with the power of prayer? ;)

If not, it seems from a regulation point of view the utility (dispatch into
"known icing")
of the aircraft would not be improved. Of course the safety of flight would
be vastly improved.
