Why is anti-ice applied on the leading edge of the wing (of a
high-altitude) and not on the fuselage?  Can we assume that friction
also generates enough heat to prevent a build-up of ice on the
fuselage?  And if so, what is the surface temperature of the fuselage at
cruising speed/altitude?

Without or without computers, how is wind & direction computed during
flight?
