Question

Where will the measurements of static pressure be most accurate?

(a) Nose of the aircraft

(b) Tail of the aircraft

(c) Wing tips of the aircraft

(d) Trailing cone

I have been asked this question in unit test.

This intriguing question originated from Air Data Equations topic in section Air Data Systems, Altitude and Heading Reference of Avionics

Answer 1

Right option is (d) Trailing cone

To explain: The most accurate value of static pressure is when the flow is least affected by the presence of the aircraft itself. In a trailing cone configuration, the probe is far behind the aircraft and is least affected by the flow.
