Question

What is equivalent air speed?

(a) The calibrated air speed corrected for scale-altitude error

(b) The true air speed corrected for scale-altitude error

(c) The indicated air speed corrected for scale-altitude error

(d) The ground air speed corrected for scale-altitude error

I got this question during a job interview.

This intriguing question comes from Measurement of Airspeed in division Atmosphere and Air Data Measurement of Aircraft Performance

Answer 1

Right choice is (a) The calibrated air speed corrected for scale-altitude error

The explanation is: Equivalent air speed is the calibrated air speed corrected for scale-altitude error. The correction is done in calibrated equation of the airspeed indicator which is a function of calibrated air speed and height.
