# Lateral axis

Lateral Axis
The axis extending through the centre of gravity of an aircraft and parallel to the wing surfaces.
Lateral Control ...

Lateral axis An imaginary line running through an aircraft from left to right through its center of gravity.
Longitudinal axis An imaginary line running through an aircraft from nose to tail.
Loop A maneuver in which an aircraft flys in a vertical circle.

lateral axis
The axis about which an aircraft pitches, extending out along each wing.
lateral stability
Stability about an airplane's longitudinal (nose to tail) axis ...

Lateral axis - an axis running from the pilot's left to right in piloted aircraft, and parallel to the wings of a winged aircraft
Longitudinal axis - an axis drawn through the body of the vehicle from tail to nose in the normal direction of flight, or the direction the pilot faces ...

Lateral Axis Straight line through the centre of gravity that runs parallel with the line that would run from wing tip to wing tip
Leading Edge The forward edge of a streamline body or aerofoil ...

Rotation about the ~ is called pitch and is controlled by the elevator.
The rotation is similar to a seesaw. The bar holding the seesaw is the ~.
This is known as the airplane's pitch attitude.

The axle should be parallel with the ~ of the machine. The center of the axle should be directly under the center of the fuselage. This can be secured by either of two methods: (a) By Measuring Cross Distances.

It is used to move the airplane about the ~. It provides the input of pitch and helps control altitude. Note the axes of rotation are discussed and illustrated below.
Vertical stabilizer -- This surface provides directional (right or left) stability. It acts like a weathervane.

They refer to the Y axis as the ~ and the X axis as the longitudinal axis, which are sensible enough, but then they refer to Y-axis stability as longitudinal stability and X-axis stability as lateral stability — which seems completely reversed and causes needless confusion.

Calculations for the ~ of the appropriate guidance modes. The control law ~ input data are: Cross Track Deviation, Cross Track Deviation Rate, Cross Track Deviation Rate Gain, Track Angle Error, Track Angle Error Gain, Course Cut Limit, Path Integral Limit, Path Integral Gain.

The elevators control the movement of the airplane about its ~. This motion is pitch. The elevators form the rear part of the horizontal tail assembly and are free to swing up and down. They are hinged to a fixed surface--the horizontal stabilizer.

The angle that an aeroplane's wings make relative to the ~ (horizontal plane, when on level ground). A larger dihedral angle gives greater roll(lateral) stability at the cost of efficiency. If the wings angle upwards, it is called the dihedral angle.

The elevon is also used as an elevator. Elevators control motion along the ~. The ~ is an imaginary line that extends crosswise, from wingtip to wingtip. Motion about the ~ is called pitch.

Dihedral. The positive acute angle between the ~ of an airplane and a line through the center of a wing or horizontal stabilizer. Dihedral contributes to the lateral stability of an airplane.

SIDESLIP - A movement of an aircraft in which a relative flow of air moves along the ~, resulting in a sideways movement from a projected flight path, especially a downward slip toward the inside of a banked turn.
