  2. Aircraft flight dynamics - Wikipedia

    en.wikipedia.org/wiki/Aircraft_flight_dynamics

    For example, a pitching moment comes from a force applied at a distance forward or aft of the cg, causing the aircraft to pitch up or down. A fixed-wing aircraft increases or decreases the lift generated by the wings when it pitches nose up or down by increasing or decreasing the angle of attack (AOA).

  3. Aircraft principal axes - Wikipedia

    en.wikipedia.org/wiki/Aircraft_principal_axes

    The position of all three axes, with the right-hand rule for describing the angle of its rotations. 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.

  4. Blade pitch - Wikipedia

    en.wikipedia.org/wiki/Blade_pitch

    Blade pitch control is a feature of nearly all large modern horizontal-axis wind turbines.It is used to adjust the rotation speed and the generated power. While operating, a wind turbine's control system adjusts the blade pitch to keep the rotor speed within operating limits as the wind speed changes.

  5. Aircraft flight control system - Wikipedia

    en.wikipedia.org/wiki/Aircraft_flight_control_system

    Cockpit controls and instrument panel of a Cessna 182D Skylane. Generally, the primary cockpit flight controls are arranged as follows: [2] A control yoke (also known as a control column), centre stick or side-stick (the latter two also colloquially known as a control or joystick), governs the aircraft's roll and pitch by moving the ailerons (or activating wing warping on some very early ...

  6. Attitude and heading reference system - Wikipedia

    en.wikipedia.org/wiki/Attitude_and_heading...

    An attitude and heading reference system (AHRS) consists of sensors on three axes that provide attitude information for aircraft, including roll, pitch, and yaw. These are sometimes referred to as MARG (Magnetic, Angular Rate, and Gravity) [ 1 ] sensors and consist of either solid-state or microelectromechanical systems (MEMS) gyroscopes ...

  7. Axes conventions - Wikipedia

    en.wikipedia.org/wiki/Axes_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 fixed at the center of gravity of the vehicle.

  8. Run and break - Wikipedia

    en.wikipedia.org/wiki/Run_and_break

    The pilot circles some distance away from airfield at high speed until the air traffic controller confirms that it is safe for the procedure to begin. Once safely cleared, the pilot aligns the aircraft with the active runway and calls initial at a set time from the airfield (usually 30 seconds or one minute).

  9. Flight dynamics - Wikipedia

    en.wikipedia.org/wiki/Flight_dynamics

    The control systems include actuators, which exert forces in various directions, and generate rotational forces or moments about the center of gravity of the aircraft, and thus rotate the aircraft in pitch, roll, or yaw. For example, a pitching moment is a vertical force applied at a distance forward or aft from the center of gravity of the ...
