A web browser navigation bar includes the back and forward buttons, as well as the Location bar where URLs are entered. [3] Formerly, the functionality of the navigation bar was split between the browser's toolbar and the address bar, but Google Chrome introduced the practice of merging the two.
To demonstrate specificity Inheritance Inheritance is a key feature in CSS; it relies on the ancestor-descendant relationship to operate. Inheritance is the mechanism by which properties are applied not only to a specified element but also to its descendants. Inheritance relies on the document tree, which is the hierarchy of XHTML elements in a page based on nesting. Descendant elements may ...
Collapsed menu ("Hamburger") icon. The hamburger button (the triple bar ≡ or trigram symbol ☰), so named for its unintentional resemblance to a hamburger, is a button typically placed in a top corner of a graphical user interface. [1]
The North American Vertical Datum of 1988 (NAVD 88) is the vertical datum for orthometric heights established for vertical control surveying in the United States based upon the General Adjustment of the North American Datum of 1988. [1] It superseded the National Geodetic Vertical Datum of 1929 (NGVD 29), [2] previously known as the Sea Level ...
In aviation, vertical navigation (VNAV, usually pronounced vee-nav) is glidepath information provided during an instrument approach, independently of ground-based navigation aids in the context of an approach and a form of vertical guidance in the context of climb/descent. An onboard navigation system displays a constant rate descent path to ...
In aviation, lateral navigation (LNAV, usually pronounced el-nav) is azimuth navigation, without vertical navigation (VNAV). Area navigation (RNAV) approach plates include LNAV as a non-precision instrument approach (NPA). When combined with VNAV, the resulting instrument approach, LNAV/VNAV, is referred to as an Approach with Vertical Guidance ...
An LPV approach is an approach with vertical guidance, APV, to distinguish it from a precision approach, PA, or a non-precision approach, NPA. SBAS criteria includes a vertical alarm limit more than 12 m, but less than 50 m, yet an LPV does not meet the ICAO Annex 10 precision approach standard. [2]
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 ...
