Question

The temperature is probe is actually an electric coil whose resistance varies with temperature.

(a) True

(b) False

I got this question by my school principal while I was bunking the class.

My enquiry is from Temperature, Angle of Attack and Angle of Side Slip Measurements topic in section Air Data Systems, Altitude and Heading Reference of Avionics

Answer 1

Correct option is (a) True

The best I can explain: The temperature probe mounted on the outside of the aircraft is usually a small coil of wire whose resistance varies with temperature. Electric heaters used for deicing must be isolated from thermometer element.
