Final answer:
An airplane tends to weathervane back to a stable position due to the wind's effect on its total velocity.
Step-by-step explanation:
An airplane tends to weathervane back to a stable position due to the wind's effect on its total velocity.
When an airplane is flying, it experiences a combination of crosswind and headwind. This results in a total velocity that is less than its velocity relative to the air mass and in a different direction.
The wind's speed and direction have a significant effect on the airplane's total velocity, and this causes the airplane to weathervane back to a stable position.
