Consists of the main gear and the nose gear. The main gear is located under the wings and includes wheels, brakes and struts. The nose gear is located under the nose of the aircraft and includes struts and wheels.
the main body of an aircraft
The major horizontal surface on an airplane that provides lift.
The controlling surface that regulates an aircraft's roll/lateral movement
Increase lift and drag
Outboard most part of the wing
Left wing light color
Right wing light color
devices located on the wings that disrupt the airflow over the wing causing loss of lift
Protrusions from the leading edge of a wing that, when combined with the flaps, result in a significant increase in lift.
Primary Flight Controls
Ailerons, Rudder, Elevator
Secondary Flight Controls
Flaps, leading edge devices, spoilers and trim devices
An airfoil (usually at the back of an airplane) that resists up and down changes in motion.
A structure that creates left to right forces to keep the fuselage aligned in yaw with the relative wind. The structure itself is vertical while the forces it creates are horizontal.
A controlling surface on an aircraft's tail that regulates yaw.
A rear horizontal stabilizer that controls up and down or pitching motion of the aircraft nose.
The tail assembly of an aircraft, including the horizontal and vertical stabilizers, elevators, and rudder.
What curve does the standard wing have?
Encompasses the limits of speed, altitude, and angle of attack required by any aircraft to maintain a stable flight.
The minimum speed at which an aircraft can maintain level flight
A force that pulls everything towards the earth at 9.8 m/s^2
An upward force created by the wing of the aircraft
The air traveling over the top of the wing is faster than the air traveling under the wing, creating lower pressure above the wing, causing lift
Resistance of the air (technically a fluid) against the forward movement of an airplane.
the pushing or pulling force exerted by the engine of an aircraft or rocket
The movement of an aircraft along the roll/longitudinal axis
The movement of the aircraft along the lateral axis
Used to level an aircraft in pitch and roll while eliminating yaw
The way objects move through air
An object whose shape contributes to lift (plane wing)
the curved part of an airfoil from its leading to trailing edge
The front, usually rounded, edge of an airplane wing or airfoil.
The last point on an airfoil that interacts with the airflow around the wing.
An imaginary straight line from the leading edge to the trailing edge of an airfoil.
Controlled space for testing air flow
a driving or propelling force in which a gas turbine engine provides the thrusting power
The measure of the force with which air molecules push on a surface
the motion of air as it relates to the aircraft within it
nautical mile, 1.15 miles per hour
Angle of Attack
The angle formed by the wing chord line and the relative wind.
The up or down movement of an aircraft.
Critical angle of attack
the point at which a plane stalls
reduction of lifting force
Speed in a given direction
center of gravity
the point around which an object's weight is evenly distributed.
balance of an aircraft
layer of air near a plane's surface
whirlpool of wind with a vacuum at its center
a one-piece body structure that offers support and rigidity
a measure of how long and wide a wing is from tip to tip
where the flight path intersects with the ground at an angle
The angle between an aircraft wing and a horizontal line.
The downward angle of an airplane's wings and tailplane from the horizontal
a plate attached to a wingtip or a wingtip bent upward
Mean Camber Line
An imaginary line between the leading and trailing edges and halfway between the airfoil's upper (curved) and lower (flat) surfaces
downward flow of air
The rear of the aircraft
a movable, hinged part that pivots down to generate more force
The difference between thrust and drag
the process of burning something
A mixture of fuel and oxidizer that burns to produce rocket thrust.
a substance that includes oxygen to aid combustion
