Aircraft Basic Definitions

 Aviation Basic Definitions  

Aircraft:  A machine that can fly, such as an airplane or helicopter.

Aerodynamics: The study of how air moves around objects, especially aircraft.

Aileron: A hinged surface on the wing that controls roll movement.

Altitude: The height of an aircraft above the ground or sea level.

Airfoil: A shape designed to produce lift when air flows over it.

Attitude: The orientation of an aircraft in relation to the horizon.

Chord Line: A straight line connecting the leading and trailing edges of a wing.

Drag: The force that resists the motion of an aircraft through the air.

Elevator: A control surface on the tail that adjusts the aircraft's pitch.

Flaps:  Movable surfaces on the wing that increase lift or drag.

Fuselage: The main body of an aircraft, where passengers and cargo are carried.

Landing Gear: The wheels or skids that allow an aircraft to land and take off.

Lift: The force that keeps an aircraft in the air, created by airflow over the wings.

Propeller: A rotating blade that generates thrust to move an aircraft forward.

Rudder: A control surface on the tail that controls yaw movement.

Stall: A condition where the wing stops generating enough lift due to a high angle of attack.

Thrust: The forward force produced by an engine or propeller.

Torque: A twisting force, often produced by an engine, that affects aircraft stability.

Turbulence: Irregular air movement that causes an aircraft to shake or move unpredictably.

Yaw: The side-to-side movement of an aircraft's nose, controlled by the rudder.
