  2. Aircraft flight dynamics - Wikipedia

    en.wikipedia.org/wiki/Aircraft_flight_dynamics

    y b axis - perpendicular to the x b,z b-plane, positive determined by the right-hand rule (generally, positive out the right wing) Wind frame Origin - airplane center of gravity; x w axis - positive in the direction of the velocity vector of the aircraft relative to the air; z w axis - perpendicular to the x w axis, in the plane of symmetry of ...

  3. Aircraft principal axes - Wikipedia

    en.wikipedia.org/wiki/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. The axes are alternatively designated as vertical, lateral (or transverse), and longitudinal respectively.

  4. Longitudinal stability - Wikipedia

    en.wikipedia.org/wiki/Longitudinal_stability

    The longitudinal stability of an aircraft, also called pitch stability, [2] refers to the aircraft's stability in its plane of symmetry [2] about the lateral axis (the axis along the wingspan). [1] It is an important aspect of the handling qualities of the aircraft, and one of the main factors determining the ease with which the pilot is able ...

  5. Center of gravity of an aircraft - Wikipedia

    en.wikipedia.org/wiki/Center_of_gravity_of_an...

    The location of the reference datum is established by the manufacturer and is defined in the aircraft flight manual. The horizontal reference datum is an imaginary vertical plane or point, placed along the longitudinal axis of the aircraft, from which all horizontal distances are measured for weight and balance purposes.

  6. Axes conventions - Wikipedia

    en.wikipedia.org/wiki/Axes_conventions

    For positive y- and z-axis, we have to face two different conventions: In case of land vehicles like cars, tanks etc., which use the ENU-system (East-North-Up) as external reference (World frame), the vehicle's (body's) positive y- or pitch axis always points to its left, and the positive z- or yaw axis always points up. World frame's origin is ...

  7. Lofting coordinates - Wikipedia

    en.wikipedia.org/wiki/Lofting_coordinates

    Two points on a fuselage at waterline 100/fuselage station 93 and waterline 101/fuselage station 276. Lofting coordinates are used for aircraft body measurements. The system derives from the one that was used in the shipbuilding lofting process, with longitudinal axis labeled as "stations" (usually fuselage stations, frame stations, FS), transverse axis as "buttocks lines" (or butt lines, BL ...

  8. Aileron roll - Wikipedia

    en.wikipedia.org/wiki/Aileron_roll

    Diagram of how an aileron roll is performed in relation to other common rolls. The aileron roll is an aerobatic maneuver in which an aircraft does a full 360° revolution about its longitudinal axis. When executed properly, there is no appreciable change in altitude and the aircraft exits the maneuver on the same heading as it entered.

  9. Flight control surfaces - Wikipedia

    en.wikipedia.org/wiki/Flight_control_surfaces

    The longitudinal axis passes through the aircraft from nose to tail. Rotation about this axis is called roll. [3] The angular displacement about this axis is called bank. [4] The pilot changes bank angle by increasing the lift on one wing and decreasing it on the other. This differential lift causes rotation around the longitudinal axis.
