The conventional pitot tube cannot be used under______(a) 100 knots(b)

1.	The conventional pitot tube cannot be used under______(a) 100 knots(b) 40 knots(c) 2 knots(d) 80 knots
Answer» The correct answer is (b) 40 knots The explanation: The conventional pitot tube and the pressure transducer become ineffective as airspeed drops below 40 knots. At the lower speeds, impact pressure is equal to dynamic pressure q, and the sensitivity of this pressure to a change in velocity is minimal.
