Which outcome occurs when an aircraft's airspeed indicator malfunctions below stall speed?

A)Loss of lift increases rapidly
B)Control surfaces lock unpredictably
C)Engine efficiency improves suddenly then fails
D)Structural icing forms instantaneously rapidly

💡 Explanation

Rapid loss of lift is triggered because airflow separation occurs due to exceeding the critical angle of attack; the airspeed indicator provides vital data for maintaining lift using lift equation; therefore, exceeding critical angle causes accelerated stall, rather than locked control surfaces or icing which depend atmosphere.
