18. An aircraft comprising:
a rotor system;
at least one control component in communication with the rotor system;
a first sensor configured to sense a first position associated with the at least one control component in a wind condition;
a second sensor configured to sense a first configuration associated with the rotor system in the wind condition;
a global position determination system comprising a third sensor configured to sense a global position of the aircraft in the wind condition; and
at least one controller in communication with each of the first sensor, the second sensor, and the third sensor, the at least one processor being configured to:
determine a tip-path-plane angle of the aircraft based on the first position, the first configuration, and the global position;
determine a current wind speed based on the tip-path-plane angle; and
control the aircraft based on the current wind speed.
