Question

what are the structures tha enable a to fly?

Answer 1

Stability and control are much more complex for an airplane, which can move freely in three dimensions, than for cars or boats, which only move in two. A change in any one of the three types of motion affects the other two.

WHAT ARE ROLL, PITCH, AND YAW?

Imagine three lines running through an airplane and intersecting at right angles at the airplane’s center of gravity.

Rotation around the front-to-back axis is called roll.

Rotation around the side-to-side axis is called pitch.

Rotation around the vertical axis is called yaw.
