Please don't make fun of an old man just short of being senile, but when we are talking about Pitot heat in a simple airplane and the risk you face if it is not working how do you get enough ice to block the airspeed indicator?
If you are slow enough in your thinking process to actually get in that situation would you rather have a heated pitot or wing anti/de ice?
If an airplane needs heated pitot/'s would it not follow it should have wing ice protection also?
