Visual Glide Slope Indicator
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. There are several different types of VGSIs: ; :; Visual Approach Slope Indicator (VASI) :; Precision Approach Path Indicator (PAPI) :; Pulsating Visual Approach Slope Indicator (PVASI) :; Three-color Visual Approach Slope Indicator (T-VASI) :; Helicopter Approach Path Indicator (HAPI) In the United States, the Federal Aviation Administration The Federal Aviation Administration (FAA) is a Federal government of the United States, U.S. federal government agency within the United States Department of Transportation, U.S. Department of Transportation that regulates civil aviation in t ... includes VGSI information in its Chart Supplement (former ...

Final Approach
In aeronautics, the final approach (also called the final leg and final approach leg) is the last leg in an aircraft's approach to landing, when the aircraft is lined up with the runway and descending for landing.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 213 and 241. Aviation Supplies & Academics, 1997. In aviation radio terminology, it is often shortened to "final". The last section of the final approach is sometimes referred to as short final. In a standard airport landing pattern, which is usually used under visual meteorological conditions (VMC), aircraft turns from base leg to final within one-half to two miles of the airport. For instrument approaches, as well as approaches into a controlled airfield under visual flight rules (VFR), often a "straight-in" final approach is used, where all the other legs are dispensed within. Straight-in approaches are discouraged at non-towered airports in the United States. Approach slope An approach slope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Visual Approach Slope Indicator
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 during the day and up to or more at night. Standard VASI Basic visual approach slope indicators consist of one set of lights set up from the start of the runway. Each light is designed so that it appears as either white or red, depending on the angle at which it is viewed. When the pilot is approaching the lights at the proper angle, meaning the pilot is on the glide slope, the first set of lights appears white and the second set appears red. When both sets appear white, the aircraft is too high, and when both appear red it is too low. This used to be the most common type of visual approach slope indicator system; however, it is being phased out and replaced by precision approach path indicators (PAPIs), which are closer together and therefore more effici ...

Precision Approach Path Indicator
A precision approach path indicator (PAPI) is a system of Electric light, lights on the side of an airport runway threshold that provides visual descent (aircraft), descent guidance information during final approach. It is generally located on the left-hand side of the runway approximately beyond the landing threshold of the runway. Design and installation A typical engineering design specification for a PAPI light unit is shown below: Optical construction: * Two lamps for redundancy; * Anodized aluminium reflectors; * Red color filter; * One or two lenses; * Lamps and reflectors replaceable without recalibration. Each light unit consists of one or more light sources, red filters and lenses. A color filter may not be necessary with colored LED lights. Each light unit emits a high-intensity beam. The lower segment of the beam is red, and the upper part is white. The transition between the two colours must take place over an angle not greater than three minutes of arc. This cha ...

A/FD
The ''Airport/Facility Directory'' (abbreviated ''A/FD''), now identified as Chart Supplement in the U.S., is a pilot's manual that provides comprehensive information on airports, large and small, and other aviation facilities and procedures. Description The directory is published in seven volumes that cover the continental United States, Puerto Rico, and the U.S. Virgin Islands. Each volume is updated every 56 days by the United States Department of Transportation (DOT) with information from the Federal Aviation Administration (FAA) and the National Aviation Charting Office (NACO). Information is provided on public-use and joint-use airports, heliports, and seaplane bases. The directory includes data that cannot be readily depicted in graphic form, including airport hours. In addition, each A/FD contains information such as parachute jumping areas and facility telephone numbers. The ''Airport/Facility Directory'' also provides a means for the FAA to communicate, in text form, u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chicago Executive Airport
Chicago Executive Airport , formerly Palwaukee Municipal Airport, is a public airport 18 miles (33 km) northwest of Chicago, in the village of Wheeling in Cook County, Illinois, United States. It is owned by the City of Prospect Heights and the Village of Wheeling. The airport logs over 77,000 take-offs and landings each year and is the fourth busiest airport in Illinois.Chicago Executive Airport Information History The airport opened in 1926 as Gauthier's Flying Field. It was named Pal-Waukee in November 1928 because of its location near the intersection of Palatine Road and Milwaukee Avenue. In 1953, the airport was purchased by George J. Priester, who developed ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheeling, Illinois
Wheeling is a village in Cook County, Illinois, Cook and Lake County, Illinois, Lake counties in the U.S. state of Illinois. A suburb of Chicago, it is primarily in Cook County, approximately northwest of downtown Chicago. Per the 2020 United States census, 2020 census, the population was 39,137. Wheeling is named after Wheeling, West Virginia. History The land that is now Wheeling, Illinois, was controlled by the Miami people, Miami Confederacy (which contained the Illinois Confederation, Illini and Kickapoo people, Kickapoo tribes) starting in the early 1680s. The Confederacy was driven from the area by the Iroquois and Meskwaki in the early 1700s. The French-allied Potawatomi began to raid and take possession of Northern Illinois in the 1700s. In the late 1700s and early 1800s, the Potawatomi expanded southwards from their territory in Green Bay and westward from their holdings in Detroit, until they controlled in an L-shaped swath of territory from Green Bay to the Illinoi ...
