Question

The purpose of aileron and elevator flutter dampers is to:

a) Improve control responsiveness.
b) Reduce control surface vibrations.
c) Enhance roll rate.
d) Prevent flutterWhen hydraulic power is lost to the PCUs

Answer 1

Aileron and elevator flutter dampers are designed to prevent flutter, which is the rapid oscillation of control surfaces potentially leading to structural failure. Their primary function is to reduce control surface vibrations and ensure flight safety.

Step-by-step explanation:

The purpose of aileron and elevator flutter dampers is to prevent flutter when there is a loss of hydraulic power to the Power Control Units (PCUs). Flutter is a dangerous condition that occurs when aerodynamic forces induce an uncontrollable, rapid oscillation of an aircraft's control surfaces, potentially leading to structural failure. Flutter dampers are designed to reduce control surface vibrations and stabilize the aircraft, thus ensuring the integrity of the control surfaces during flight. While they may indirectly affect control responsiveness and roll rate, their primary function is not to enhance these characteristics but to provide a safety mechanism against flutter.
