# Aircraft principal axes

An aircraft in flight is free to rotate in three dimensions: yaw, nose left or right about an axis running up and down; pitch, nose up or down about an axis running from wing to wing; and roll, rotation about an axis running from nose to tail. [1]

## Aerodynamics

Aerodynamics, from Greek ἀήρ aer (air) + δυναμική (dynamics), is the study of the motion of air, particularly its interaction with a solid object, such as an airplane wing.

## Aileron

An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft.

## Aircraft

An aircraft is a machine that is able to fly by gaining support from the air.

## Aircraft flight control system

A conventional fixed-wing aircraft flight control system consists of flight control surfaces, the respective cockpit controls, connecting linkages, and the necessary operating mechanisms to control an aircraft's direction in flight.

## Axes conventions

In ballistics and flight dynamics, axes conventions are standardized ways of establishing the location and orientation of coordinate axes for use as a frame of reference.

## Center of mass

In physics, the center of mass of a distribution of mass in space is the unique point where the weighted relative position of the distributed mass sums to zero, or the point where if a force is applied it moves in the direction of the force without rotating.

## Elevator (aeronautics)

Elevators are flight control surfaces, usually at the rear of an aircraft, which control the aircraft's pitch, and therefore the angle of attack and the lift of the wing.

## Euler angles

The Euler angles are three angles introduced by Leonhard Euler to describe the orientation of a rigid body with respect to a fixed coordinate system.

## Fixed-wing aircraft

A fixed-wing aircraft is an aircraft, such as an airplane or aeroplane (note the two different spellings), which is capable of flight using wings that generate lift caused by the vehicle's forward airspeed and the shape of the wings.

## Flight control surfaces

Aircraft flight control surfaces are aerodynamic devices allowing a pilot to adjust and control the aircraft's flight attitude.

## Flight dynamics

Flight dynamics is the study of the performance, stability, and control of vehicles flying through the air or in outer space.

## Frenet–Serret formulas

In differential geometry, the Frenet–Serret formulas describe the kinematic properties of a particle moving along a continuous, differentiable curve in three-dimensional Euclidean space ℝ3, or the geometric properties of the curve itself irrespective of any motion.

## Moment (physics)

In physics, a moment is an expression involving the product of a distance and a physical quantity, and in this way it accounts for how the physical quantity is located or arranged.

## Moving frame

In mathematics, a moving frame is a flexible generalization of the notion of an ordered basis of a vector space often used to study the extrinsic differential geometry of smooth manifolds embedded in a homogeneous space.

## Panning (camera)

In cinematography and photography panning means swivelling a still or video camera horizontally from a fixed position.

## Parallel (geometry)

In geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel.

## Perpendicular

In elementary geometry, the property of being perpendicular (perpendicularity) is the relationship between two lines which meet at a right angle (90 degrees).

## Reaction control system

A reaction control system (RCS) is a spacecraft system that uses thrusters to provide attitude control, and sometimes translation.

## Rudder

A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other conveyance that moves through a fluid medium (generally air or water).

## Screw theory

Screw theory is the algebra and calculus of pairs of vectors, such as forces and moments and angular and linear velocity, that arise in the kinematics and dynamics of rigid bodies.

## Six degrees of freedom

Six degrees of freedom (6DoF) refers to the freedom of movement of a rigid body in three-dimensional space.

## Spacecraft

A spacecraft is a vehicle or machine designed to fly in outer space.

## Torque

Torque, moment, or moment of force is rotational force.

Triad is one of the earliest and simplest solutions to the spacecraft attitude determination problem, due to Harold Black.

## Waterline

The waterline is the line where the hull of a ship meets the surface of the water.

## Wright brothers

The Wright brothers, Orville (August 19, 1871 – January 30, 1948) and Wilbur (April 16, 1867 – May 30, 1912), were two American aviators, engineers, inventors, and aviation pioneers who are generally credited with inventing, building, and flying the world's first successful airplane.
