I disagree...we all know that with drop in pressure on the upper surface of the wing (which is associated with a drop in temperature) which only occurs in flight (not on the ground) might not be exactly ten degrees but is an insignificant difference from the drop in the intake. The ice detector being shaped like a wing (also being subject to the change in pressure and temperature) makes all parts of the aircraft including the part detecting ice...the SAME TEMPERATURE! So why then do we ever use the OVRD switch? Only on operations on the ground where the wing and stab are not subject to the change in pressure and temperature and in flight when the ice detectors fails.
