flaw. An imperfection in a material, often concealed, that impairs soundness. fleet weight (aircraft operation). The average weight of aircraft of the same model that have the same equipment installed. Operations under 14 CFR Part 121 and 135 may use fleet weight, rather than having to weigh each individual aircraft. Fleming’s rule for direction of magnetic flux. Place the fingers of the right hand around a current-carrying conductor in such a way that the thumb points in the direction of conventional current flow (from positive to negative). The fingers encircle the wire in the same direction as the lines of flux. Fleming’s rule for electric generators. This is the rule for determining the direction of current flow in a wire caused by the wire passing through a magnetic field. Hold the right hand with the thumb, first finger, and second finger extended so that they are at right angles to each other. When the first finger points in the direction of the lines of magnetic flux (from the north pole to the south pole), and the thumb points in the direction the wire is moving through the field, the second finger points in the direction of conventional current flow (from positive to negative). Fleming’s rule for electric motors. The rule for determining the direction of movement of a current-carrying conductor in a magnetic field. Hold the left hand with the thumb, first finger, and second finger extended so that they are at right angles to each other. When the first finger points in the direction of the lines of magnetic flux (from the north pole to the south pole), and the second finger points in the direction of conventional current flow (from positive to negative), the thumb points in the direction the conductor will move. flexibility. The characteristic of a material that allows it to be repeatedly bent within its elastic limits and still return to its original condition each time the bending force is removed. flexible control cable (aircraft control system component). A steel cable used to connect the cockpit “Flight check” (air traffic control). A call-sign prefix used by FAA aircraft engaged in flight inspection/certification of navigational aids and flight procedures. |
