← ScienceWhich outcome occurs when a pitot tube measures the airspeed of an aircraft encountering freezing rain?
A)Icing causes pressure reading increase
B)Bernoulli's equation becomes inapplicable✓
C)Dynamic pressure calculation stabilizes correctly
D)Static port blockage underestimates airspeed
💡 Explanation
Icing obstructs the pitot tube, and Bernoulli's equation, relating pressure and velocity for a streamline breaks down because the fluid assumptions are invalid; therefore no accurate airspeed results, rather than simple over/underestimation which assumes valid fluid dynamics.
