  2. Stabilizer (aeronautics) - Wikipedia

    en.wikipedia.org/wiki/Stabilizer_(aeronautics)

    A Boeing 737 uses an adjustable stabilizer, moved by a jackscrew, to provide the required pitch trim forces. Generic stabilizer illustrated. A horizontal stabilizer is used to maintain the aircraft in longitudinal balance, or trim: [3] it exerts a vertical force at a distance so the summation of pitch moments about the center of gravity is zero. [4]

  3. Trim drag - Wikipedia

    en.wikipedia.org/wiki/Trim_drag

    Trim drag, denoted as Dm in the diagram, is the component of aerodynamic drag on an aircraft created by the flight control surfaces, [1] mainly elevators and trimable horizontal stabilizers, when they are used to offset changes in pitching moment and centre of gravity during flight.

  4. Radio-controlled aerobatics - Wikipedia

    en.wikipedia.org/wiki/Radio-controlled_aerobatics

    The aircraft should exhibit the Lomcevak while spiraling downwards. Exit the maneuver as the above method. This maneuver calls for a specific type of aircraft. Since the motion involves rapid downward pitch, a low-wing aircraft with high thrustline is desirable, as it naturally creates the downward pitch moment.

  5. Chord (aeronautics) - Wikipedia

    en.wikipedia.org/wiki/Chord_(aeronautics)

    The wing, horizontal stabilizer, vertical stabilizer and propeller/rotor blades of an aircraft are all based on aerofoil sections, and the term chord or chord length is also used to describe their width. The chord of a wing, stabilizer and propeller is determined by measuring the distance between leading and trailing edges in the direction of ...

  6. Stabilator - Wikipedia

    en.wikipedia.org/wiki/Stabilator

    Grumman F-14 Tomcat jet fighter during a takeoff, with stabilators deflected upwards. A stabilator is a fully movable aircraft horizontal stabilizer.It serves the usual functions of longitudinal stability, control and stick force requirements [1] otherwise performed by the separate parts of a conventional horizontal stabilizer (which is fixed) and elevator (which is adjustable).

  7. Radio-controlled aircraft - Wikipedia

    en.wikipedia.org/wiki/Radio-controlled_aircraft

    3D flight is a type of flying in which model aircraft have a thrust-to-weight ratio of more than 1:1 (typically 1.5:1 or more), large control surfaces with extreme throws, low weight compared to other models of same size and relatively low wing loadings. Simply put, 3D flight is the art of flying a plane below its stall speed (the speed at ...

  8. Stability derivatives - Wikipedia

    en.wikipedia.org/wiki/Stability_derivatives

    The stability axis system is used to get the X axis aligned with the oncoming flow direction. Essentially, the body axis system is rotated about the Y body axis by the trim angle of attack and then "re-fixed" to the body of the aircraft: [1] X stability axis is aligned into the direction of the oncoming air in steady flight.

  9. Elevator (aeronautics) - Wikipedia

    en.wikipedia.org/wiki/Elevator_(aeronautics)

    The elevator is a usable up and down system that controls the plane, horizontal stabilizer usually creates a downward force which balances the nose down moment created by the wing lift force, which typically applies at a point (the wing center of lift) situated aft of the airplane's center of gravity.
