The visual approach slope indicator (VASI) is a system of lights on the side of an airport runway threshold that provides visual descent guidance information during final approach. These lights may be visible from up to 8 kilometres (5.0 mi) during the day and up to 32 kilometres (20 mi) or more at night.
Color Hue is the visual property caused by the blending of various wavelengths of light, which we commonly refer to by color names like "red," "green," or "blue." Maps often use hue to differentiate categories of nominal variables, such as land cover types or geologic layers, [ 13 ] or for its psychological connotations , such as red implying ...
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
The design of a dashboard is more loosely defined. Dashboards are usually a series of graphics, charts, gauges and other visual indicators that can be monitored and interpreted. Even when there is a strategic link, on a dashboard, it may not be noticed as such since objectives are not normally present on dashboards.
Visual Glide Slope Indicator or Visual Glideslope Indicator (VGSI) is a ground device that uses lights to assist a pilot in landing an airplane at an airport.The lights define a vertical approach path during the final approach to a runway and can help the pilot determine if the airplane is too high or too low for an optimum landing.
Dashboard instruments displaying various car and engine conditions. Where the dashboard originally included an array of simple controls (e.g., the steering wheel) and instrumentation to show speed, fuel level and oil pressure, the modern dashboard may accommodate a broad array of gauges, and controls as well as information, climate control and entertainment systems.
[4] [3] In figure 5, several related terms and symbols are shown. Focal length (f) refers to the elevation difference between the film and the lens. [2] [4] H is the elevation difference between the lens and the sea level, which is the average level of the water surface. [2] [4] h is the elevation difference between the terrain surface and the ...
