  2. Course deviation indicator - Wikipedia

    en.wikipedia.org/wiki/Course_deviation_indicator

    It then shows the number of degrees deviation between the aircraft's current position and the "radial" line emanating from the signal source at the given bearing. This can be used to find and follow the desired radial. Deflection is 10° deviation at full scale (each side), with each dot on the CDI representing 2°.

  3. Localizer type directional aid - Wikipedia

    en.wikipedia.org/wiki/Localizer_Type_Directional_Aid

    (At each "edge-of-course", commonly 1.5 or 3 degrees left and right of course, the transmitted signal is created in such a way as to ensure full-scale CDI needle deflection at and beyond these edges, so the pilot will never falsely believe they are intercepting the course outside of the actual course area.

  4. VHF omnidirectional range - Wikipedia

    en.wikipedia.org/wiki/VHF_omnidirectional_range

    DVOR (Doppler VOR) ground station, collocated with DME. On-board VOR display with CDI MCT DVOR, Manchester Airport, United Kingdom.. Very High Frequency Omnidirectional Range Station (VOR) [1] is a type of short-range VHF radio navigation system for aircraft, enabling aircraft with a VOR receiver to determine the azimuth (also radial), referenced to magnetic north, between the aircraft to/from ...

  5. Deflection (engineering) - Wikipedia

    en.wikipedia.org/wiki/Deflection_(engineering)

    Deflection (f) in engineering. In structural engineering, deflection is the degree to which a part of a long structural element (such as beam) is deformed laterally (in the direction transverse to its longitudinal axis) under a load. It may be quantified in terms of an angle (angular displacement) or a distance (linear displacement).

    Also pictured below is the "deflection board", used to correct for any of the factors #6 through #9 above. The Model 1905 board is shown in the two images below. [note 10] This device had a movable T-square and also a movable brass frame (or platen), both of which could be slid back and forth independently across three scales that ran across ...

  7. Degree of curvature - Wikipedia

    en.wikipedia.org/wiki/Degree_of_curvature

    Curvature is usually measured in radius of curvature.A small circle can be easily laid out by just using radius of curvature, but degree of curvature is more convenient for calculating and laying out the curve if the radius is as large as a kilometer or mile, as is needed for large scale works like roads and railroads.

    The television term “pilot” is likely inspired by the aviation industry, given it's the first time a show lifts off or "airs." Like an airline pilot operating a plane, these episodes steer ...

    The Children's Depression Inventory (CDI and CDI2) is a psychological assessment that rates the severity of symptoms related to depression or dysthymic disorder in children and adolescents. [1] The CDI is a 27-item scale that is self-rated and symptom-oriented. [1] The assessment is now in its second edition.
