Control surface inputs cause movement around how many axes of rotation through the Center of Gravity?

Control surface inputs on an unmanned aircraft affect movement around three axes of rotation through the Center of Gravity. These axes are:

1. Pitch Axis: This axis runs from wingtip to wingtip. Control surfaces like the elevator are responsible for controlling the aircraft's pitch, which is the up or down movement of the nose.

2. Roll Axis: This axis extends from the nose to the tail. The ailerons are the primary control surfaces that manage roll, allowing the aircraft to bank left or right.

3. Yaw Axis: This axis runs vertically through the Center of Gravity. The rudder influences yaw, which is the left or right movement of the aircraft's nose.

Each of these axes represents a fundamental way in which the aircraft can maneuver, and control surfaces are specifically designed to manage these movements. Understanding the three axes helps in grasping how control inputs translate into actual aircraft movement, which is essential for safely operating and piloting unmanned aircraft systems.
