Question

The rate of the change in the cabin pressure should not exceed ______ at sea level.

(a) 30 ft/min

(b) 3000 ft/min

(c) 3 ft/min

(d) 300 ft/min

This question was addressed to me in an interview for internship.

This intriguing question originated from Descent Performance in Aircraft Operations topic in portion Climb and Descent Performance of Aircraft Performance

Answer 1

The correct answer is (d) 300 ft/min

The best I can explain: The rate of the change in the cabin pressure should not exceed 300 ft/min at sea level. This states that the cabin is pressurized to 8000ft pressure height, the descent to the sea level should not exceed 24 minutes before the take-off.
