Last time I checked if you take wings off the fuselage, it doesn't create lift and falls like a rock. Nor is the fuselage heated to prevent ice buildup, yet airplanes are flying around just fine in ice. How many years has the mighty 200 been flying without full type 4? Suddenly we need to create heavy work load in horrible weather conditions, destroy a bunch of apu's after they injest fluid, and pop everyone's ear drums in the process.
