Question

Where are self-aligning pitot tubes used?

(a) Bomber planes

(b) Commercial airliners

(c) High angle of attack fighter aircraft

(d) General aviation

I got this question during an online exam.

This is a very interesting question from Pressure Measurements topic in division Air Data Systems, Altitude and Heading Reference of Avionics

Answer 1

Right option is (c) High angle of attack fighter aircraft

Explanation: When the angle of attack and the sideslip angle are under 10°, they do not affect the pressure measurements much. In applications such as high angle of attack fighters, special self-aligning pitot tubes are used to measure the stagnation pressure.
