Abstract
A hybrid heater system for an aircraft air data sensor includes a voltage source and a first hybrid heater set. The first hybrid heater set includes a carbon nanotube (CNT) heater, a first positive temperature coefficient (PTC) heater disposed in parallel with the CNT heater to form a parallel formation, and a second PTC heater disposed in series between the voltage source and the parallel formation.
