What are the four dynamic forces that act on an airplane during all maneuvers? (FAA‑H‑8083‑25)
Lift—the upward acting force.
Gravity—or weight, the downward acting force.
Thrust—the forward acting force.
Drag—the backward acting force.
The four dynamic forces that act on an airplane during all maneuvers are:
1. Lift: It is the upward force that is generated by the wings of the airplane as it moves through the air. Lift opposes the force of weight, which is the force of gravity acting on the airplane.
2. Weight: It is the force of gravity acting on the airplane. Weight opposes the force of lift generated by the wings.
3. Thrust: It is the force that propels the airplane forward. Thrust is generated by the engines of the airplane.
4. Drag: It is the resistance of the air acting on the airplane as it moves through it. Drag opposes the force of thrust generated by the engines.
All four of these forces play an important role in the flight of an airplane, and they must be balanced properly for an airplane to maintain stable flight.
Any changes to one or more of these forces can affect the flight characteristics of an airplane.
