Question

Which is the optimum place for a temperature probe?

(a) Landing gear

(b) Inside cockpit

(c) Exit of engine

(d) Tip of vertical tail

I have been asked this question in semester exam.

My doubt stems from Temperature, Angle of Attack and Angle of Side Slip Measurements topic in division Air Data Systems, Altitude and Heading Reference of Avionics

Answer 1

Correct choice is (d) Tip of vertical tail

For explanation: Probes may be mounted on the wing tips, vertical tail, forward fuselage or other areas where the local mach number is the same as the free stream mach number for all expected flight altitudes and speeds.
