life in the corners is rarely that simple..
Icing is a tough taskmaster.
In a prior life I worked beside a group that did way-excellent ultrasonic anemometers .. but they'd be useless iced over.. yes, they can be heated, but so can pitot tubes..
I have not spent a lot of time in the technology of laser anemometers, but I can see how things might get challenging with particles of varying aerodynamic parameters flying every which way in an MCS..
one needs to be careful when looking for technological silver bullets.. PCBs, anyone?
