← TechnologyWhich outcome will occur in an aircraft if the stability augmentation system (SAS) actuators exceed their maximum rate limits?
A)Control surface reversal (oscillation)✓
B)Increased aerodynamic stall margin
C)Enhanced passenger ride comfort
D)Improved fuel consumption efficiency
💡 Explanation
Control surface reversal appears because exceeding the SAS rate limits leads to phase lag in the flight control hydraulic actuators, thereby creating unintended oscillations rather than stabilizing motion; therefore, the aircraft control is then destabilized rather than enhanced.
