Aircraft certified for known icing??

Perhaps that was a later modification contributing to the belief that the reg itself went into effect in the 70's.

That may be it.

A major overhaul of the 1966 regs might consitute the basis for just such a belief.

Now we have moving map displays, GPS, hot props, boots and all that good stuff. So I guess what we get now is high tech icing, I guess the guys in N.H. found out how a Cherokee Six handles iciing with a load. I think the whole world has become icing complacent, so here we go in a full circle again all bought with blood. I took off from DTW the other night with an RVR of 1500 in snow and fog. I had to get the airplane deiced before I left due to 2 inches of rime left there from the previous crew. I knew there may be ice, I was on top at 6000 feet with neg ice. I called up flight watch and passed that on to them and they acted like they could have cared less. When I was flying up north I would die waiting for a Pirep like that. I told myself if I ever flew an airliner I would surely pass the info on. I guess if the system doesn't care then way should the user. Be careful guys ice will kill you.
