← ScienceWhich consequence results when a supersonic aircraft's ascent profile violates the area rule equation?
A)Increased transonic wave drag develops✓
B)Elevator control effectiveness diminishes severely
C)Engine stall probability during climb increases
D)Boundary layer separation causes flow reversal
💡 Explanation
Increased transonic wave drag develops because when the area rule is violated, the aircraft's cross-sectional area changes abruptly along its length leading to greater air compression as it approaches Mach 1; therefore wave drag acutely increases rather than other aerodynamic instabilities.
