← TechnologyWhich mechanism causes erratic aircraft flight when encountering a microburst induced wind shear?
A)Adverse pressure gradient stall✓
B)Compressibility shock wave formation
C)Bernoulli effect lift augmentation
D)Parasitic drag profile increase
💡 Explanation
An adverse pressure gradient stall leads to erratic flight because separation of airflow over the airfoil occurs, thereby decreasing lift and increasing drag. Therefore, the wing stalls, rather than experiencing increased lift from Bernoulli's principle, which assumes attached flow.
