Wing

Airframe

The wing is the airplane’s main lifting surface. Its shape and angle to the airflow affect the lift it produces.

Look for

Trace the main wing, then find the smaller movable surfaces along its rear edge.

Think it through

Are the wing and its aileron the same part?

Airframe notes

Turn on JavaScript to select parts in the diagram. You can read the introductory notes here.

Wing: The wing is the airplane’s main lifting surface. Its shape and angle to the airflow affect the lift it produces.
Aileron: Ailerons control roll: the motion that raises one wing and lowers the other.
Flap: Flaps change the wing’s shape and its lift and drag characteristics when extended.
Engine & propeller: Each engine supplies power to a propeller, which produces thrust. The Seminole has two engines.
Stabilator: A stabilator is a movable horizontal tail surface that controls pitch: nose-up and nose-down rotation.
Rudder: The rudder controls yaw: rotation that points the nose left or right about the vertical axis.
Landing gear: The landing gear supports the airplane on the ground. Wheels and supporting structures carry the ground loads.
Antenna: Antennas transmit or receive radio signals. Their equipment, number and placement vary with the aircraft’s configuration and must be verified in its documentation.

A little context.

Explore the whole, then understand the parts.

What you'll learn

Identify the major external parts of a twin-engine aircraft.
Connect a part's shape and position with its general function.

Before you begin

No prior experience needed.

This exercise introduces major external aircraft parts. Select a label or use the part list to connect each component with a short explanation.

The illustrations simplify the aircraft to make relationships easier to see. They do not show an inspection sequence or establish an aircraft’s airworthiness. Use the applicable aircraft documentation and instruction for operational tasks.

About this draft & its limitations

The 3D illustration and fallback schematics use simplified proportions. Moving controls illustrate geometry, not aircraft operating settings or procedures. Component positions and equipment must be checked against the specific aircraft documentation. The original supplied HTML was incomplete, so this is a new draft reconstruction, not a verified reproduction.
