Ellington Airport is a privately owned, public use airport located two nautical miles (4 km) north of the central business district of Ellington, a town in Tolland County, Connecticut, United States. The airport, which is open to the public, is one of two Connecticut airports that is state certified as a parachute jump zone. Connecticut Parachutists Inc. has its home base at the airport. Facilities and aircraft Ellington Airport covers an area of 15 acres (6 ha) at an elevation of 253 feet (77 m) above mean sea level. It has one runway designated 1/19 with an asphalt surface measuring 1,800 by 50 feet (549 x 15 m).

Ellington, Connecticut
Ellington is a town in Tolland County, Connecticut, United States. Ellington was incorporated in May 1786, from East Windsor. As of the 2020 census, the town population was 16,426. History Originally the area in what is now Ellington was named by the natives as “Weexskashuck” which translates to “Great Marsh”. The earliest settlers called the area Great Marsh or Goshen. In 1671, the town of Windsor, purchased the land of East Windsor and Ellington from the Native Americans to recover land loss from the Connecticut-Massachusetts border dispute. Though no one attempted to settle the fertile lands for another 50 years. Samuel Pinney was the first settler in today's Ellington (Pinney Road bears his name in town). In 1733, Ellington was established as a Parish of the town of Windsor. East Windsor then split off from Windsor and held land in what is today's East Windsor, South Windsor and Ellington in May 1768. Ellington split off twenty years later and incorporated itself in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mean Sea Level
There are several kinds of mean in mathematics Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics ..., especially in statistics. Each mean serves to summarize a given group of data, often to better understand the overall value (magnitude (mathematics), magnitude and sign (mathematics), sign) of a given data set. For a data set, the ''arithmetic mean'', also known as "arithmetic average", is a measure of central tendency of a finite set of numbers: specifically, the sum of the values divided by the number of values. The arithmetic mean of a set of numbers ''x''1, ''x''2, ..., x''n'' is typically denoted using an overhead bar, \bar. If the data set were based on a series of observations obtained by sampling (statistics), sampling from a statistical population, the arithmetic mean is th ...

The National Map
''The National Map'' is a collaborative effort of the United States Geological Survey (USGS) and other federal, state, and local agencies to improve and deliver topographic information for the United States. The purpose of the effort is to provide "...a seamless, continuously maintained set of public domain geographic base information that will serve as a foundation for integrating, sharing, and using other data easily and consistently". ''The National Map'' is part of the USGS National Geospatial Program. The geographic information available includes orthoimagery (aerial photographs), elevation, geographic names, hydrography, boundaries, transportation, structures and land cover. ''The National Map'' is accessible via the Web, as products and services, and as downloadable data. Its uses range from recreation to scientific analysis to emergency response. ''The National Map'' is a significant contribution to the U.S. National Spatial Data Infrastructure (NSDI) from the Federa ...

USGS
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredth anniv ...

Ultralight
Ultralight aviation (called microlight aviation in some countries) is the flying of lightweight, 1- or 2-seat fixed-wing aircraft. Some countries differentiate between weight-shift control and conventional three-axis control aircraft with ailerons, elevator and rudder, calling the former "microlight" and the latter "ultralight". During the late 1970s and early 1980s, mostly stimulated by the hang gliding movement, many people sought affordable powered flight. As a result, many aviation authorities set up definitions of lightweight, slow-flying aeroplanes that could be subject to minimum regulations. The resulting aeroplanes are commonly called "ultralight aircraft" or "microlights", although the weight and speed limits differ from country to country. In Europe, the sporting (FAI) definition limits the maximum stalling speed to and the maximum take-off weight to , or if a ballistic parachute is installed. The definition means that the aircraft has a slow landing speed and short ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
