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.
Magnetic Heading The direction an aircraft faces as indicated by a magnetic compass.
longitudinal axis
The axis about which an aircraft rolls, extending from nose to tail

Longitudinal Axis: A line fore and aft through the centre of gravity of an aeroplane and parallel to the line of flight.
Longitudinal Divergence: The pitching motion of an aeroplane which precedes a dive or a stall.
Longitudinal Axis Straight line through the centre of gravity that runs parallel with the line that would run from nose to tail
Magnetic Course The angle (measured in a clockwise direction) between the course of an aeroplane and Magnetic North ...
Rotation about the longitudinal axis is called roll and is controlled by the outboard movable portions of each wing: the ailerons. The term "aileron" is the French word for "little wing.
Bank: Aspect of Rotation of airplane about its longitudinal axis.
Barrel Roll: Airplane rolled about a line offset but parallel to its longitudinal axis.

The horizontal reference datum is an imaginary vertical plane or point, arbitrarily fixed somewhere along the longitudinal axis of the aircraft, from which all horizontal distances are measured for weight and balance purposes.
The wing down method consists of keeping the airplane's longitudinal axis aligned with the flight path and the runway by lowering the windward wing while applying opposite rudder. If this sounds like the definition of a slip, it is precisely that.
They refer to the Y axis as the lateral axis 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 — ...
Angle of Incidence: The angle of incidence is the angle formed by the longitudinal axis of the airplane and the chord of the wing. The longitudinal axis is an imaginary line that extends lengthwise through the fuselage from nose to tail.
Longitudinal Guidance: Calculations for the longitudinal axis of the guidance modes. The control law longitudinal axis input data are: Reference Acceleration, Reference Acceleration Gain, Desired Velocity, Velocity Error Scale Factor.
The two ailerons, one at the outer trailing edge of each wing, are movable surfaces that control movement about the longitudinal axis. The movement is roll. Lowering the aileron on one wing raises the aileron on the other.
Thus the longitudinal axis of the aircraft is at an angle to the runway while its ground track is along the extended centerline of the runway.
Buttock line (BL) - The longitudinal axis of the aircraft that serves as the reference location for positions to the left and right of center. The positions are usually dimensioned in inches.

TAILWIND- Any wind more than 90 degrees to the longitudinal axis of the runway. The magnetic direction of the runway shall be used as the basis for determining the longitudinal axis.

Heading in the direction in which the longitudinal axis (the nose) is pointing.
It is usually expressed as a three-figure group with reference to magnetic north.

This is the angle that is measured between the longitudinal axis, running through the length of the aircraft, and the chord line of the wing.
A rotation of an aircraft around the longitudinal axis. This effect is produced by the ailerons.

The operator holds the scribe by the end of the long handle and pressing the point of the pin into the grain, pulls the scribe in the direction of the longitudinal axis or what appears to be the grain direction.

Ailerons. Primary flight control surfaces mounted on the trailing edge of an airplane wing, near the tip. Ailerons control roll about the longitudinal axis.
Aircraft. A device that is used, or intended to be used, for flight.
ANGLE OF INCIDENCE - The angle at which an airfoil is normally fixed in relation to the longitudinal axis of an aircraft.
roll - A basic aircraft maneuver, used to rotate or turn the aircraft to one side along its longitudinal axis, created by an up or down motion of the wings.
