(a) 959.1m/s

(b) 1000m/s

(c) 981m/s

(d) 954m/s

I have been asked this question by my school principal while I was bunking the class.

I need to ask this question from Measurement of Airspeed in division Atmosphere and Air Data Measurement of Aircraft Performance

Best answer
Correct choice is (a) 959.1m/s

For explanation: The answer is 959.1m/s. Given V=330m/s, σ=8.447. From the equation Ve=V\(\sqrt{\sigma}\)

Ve=330\(\sqrt{8.447}\)

Ve=959.1m/s.
