Question

The dutch roll mode of the aircraft can be excited by applying

• A. a step input to the elevators
• B. a step input to the rudder
• C. a sinusoidal input to the aileron
• D. an impulse input to the elevators

Hint:

Rudder inputs introduce yaw motion, initiating the characteristic dutch roll oscillation.

Answer 1

The Correct Option is B

Dutch roll — a coupled yawing and rolling oscillation — is typically triggered by a step rudder input.
