New Braunfels Regional Airport
New Braunfels National Airport is a public use airport in Guadalupe County, Texas, United States. It is owned by the city of New Braunfels and located four nautical miles (5 mi, 7 km) east of its central business district. Formerly known as New Braunfels Regional Airport, it is included in the National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a ''general aviation'' facility. Although most U.S. airports use the same three-letter location identifier for the FAA and IATA, this airport is assigned BAZ by the FAA but has no designation from the IATA (which assigned BAZ to Barcelos Airport in Barcelos, Amazonas, Brazil). From 1940 to 1967, it operated as Clear Springs Air Force Base. Facilities and aircraft New Braunfels National Airport covers an area of 900 acres (364 ha) at an elevation of 651 feet (198 m) above mean sea level.

New Braunfels, Texas
New Braunfels ( ) is a city in Comal and Guadalupe counties in the U.S. state of Texas known for its German Texan heritage. It is the seat of Comal County. The city covers and had a population of 90,403 as of the 2020 Census. A suburb just north of San Antonio, and part of the Greater San Antonio metropolitan area, it was the third-fastest-growing city in the United States from 2010–2020. History New Braunfels was established in 1845 by Prince Carl of Solms-Braunfels, Commissioner General of the Mainzer Adelsverein, also known as the Noblemen's Society. Prince Carl named the settlement in honor of his home of Solms-Braunfels, Germany. The Adelsverein organized hundreds of people in Germany to settle in Texas. Immigrants from Germany began arriving at Galveston in July 1844. Most then traveled by ship to Indianola in December 1844, and began the overland journey to the Fisher-Miller land grant purchased by Prince Carl. At the urging of John Coffee Hays, who realized the se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Airports In Texas
The Texas Department of Transportation (TxDOT) is a governmental agency and its purpose is to "provide safe, effective, and efficient movement of people and goods" throughout the state. Though the public face of the agency is generally associated with maintenance of the state's immense highway system, the agency is also responsible for aviation in the state and overseeing public transportation systems. Highways Texas freeways have on heavily traveled since their 1948 beginnings with a several-mile stretch of Houston's Gulf Freeway, and are often under construction to meet the demands of continuing growth. As of 2005, there were of public highway in Texas (up from in 1984). Texas Department of Transportation (TxDOT) planners have sought ways to reduce rush hour congestion, primarily through High-occupancy vehicle (HOV) lanes for vans and carpools. The "Texas T", an innovation originally introduced in Houston, is a ramp design that allows vehicles in the HOV lane, which is us ...

Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most comm ...

Jet Aircraft
A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by jet engines. Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines achieve maximum efficiency at speeds close to or even well above the speed of sound. Jet aircraft generally cruise most efficiently at about Mach 0.8 () and at altitudes around or more. The idea of the jet engine was not new, but the technical problems involved could not begin to be solved until the 1930s. Frank Whittle, an English inventor and RAF officer, began development of a viable jet engine in 1928, and Hans von Ohain in Germany began work independently in the early 1930s. In August 1939 the turbojet powered Heinkel He 178, the world's first jet aircraft, made its first flight. A wide range of different types of jet aircraft exist, both for civilian and military purposes. History After the first instance of powered f ...

Aircraft Engine
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Most aircraft engines are either piston engines or gas turbines, although a few have been rocket powered and in recent years many small UAVs have used electric motors. Manufacturing industry In commercial aviation the major Western manufacturers of turbofan engines are Pratt & Whitney (a subsidiary of Raytheon Technologies), General Electric, Rolls-Royce, and CFM International (a joint venture of Safran Aircraft Engines and General Electric). Russian manufacturers include the United Engine Corporation, Aviadvigatel and Klimov. Aeroengine Corporation of China was formed in 2016 with the merger of several smaller companies. The largest manufacturer of turboprop engines for general aviation is Pratt & Whitney. General Electric announced in 2015 entrance into the market.

Air Taxi
An air taxi is a small commercial aircraft that makes short flights on demand. In 2001 air taxi operations were promoted in the United States by a NASA and aerospace industry study on the potential Small Aircraft Transportation System (SATS) and the rise of light-jet aircraft manufacturing. Since 2016, air taxis have reemerged as part of the burgeoning field of eVTOL. Regulation In Canada, air taxi operations are regulated by Transport Canada under Canadian Aviation Regulation 703. The Canadian definition of air taxi includes all commercial single-engined aircraft, multi-engined helicopters flown by visual flight rules by one pilot and all multi-engined, non-turbo-jet aircraft, with a maximum take-off weight or less and nine or fewer passenger seats, that are used to transport people or goods or for sightseeing. In the US, air taxi and air charter operations are governed by 14 CFR Part 135 and 14 CFR part 298 of the Federal Aviation Regulations (FAR).

Asphalt Concrete
Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams. Asphalt mixtures have been used in pavement construction since the beginning of the twentieth century. It consists of mineral aggregate bound together with asphalt, laid in layers, and compacted. The process was refined and enhanced by Belgian-American inventor Edward De Smedt. The terms ''asphalt'' (or ''asphaltic'') ''concrete'', ''bituminous asphalt concrete'', and ''bituminous mixture'' are typically used only in engineering and construction documents, which define concrete as any composite material composed of mineral aggregate adhered with a binder. The abbreviation, ''AC'', is sometimes used for ''asphalt concrete'' but can also denote ''asphalt content'' or ''asphalt cement'', ...

Runway
According to the International Civil Aviation Organization (ICAO), a runway is a "defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft". Runways may be a man-made surface (often asphalt concrete, asphalt, concrete, or a mixture of both) or a natural surface (sod, grass, soil, dirt, gravel, ice, sand or road salt, salt). Runways, as well as taxiways and Airport apron, ramps, are sometimes referred to as "tarmac", though very few runways are built using Tarmacadam, tarmac. Takeoff and landing areas defined on the surface of water for seaplanes are generally referred to as waterways. Runway lengths are now International Civil Aviation Organization#Use of the International System of Units, commonly given in meters worldwide, except in North America where feet are commonly used. History In 1916, in a World War I war effort context, the first concrete-paved runway was built in Clermont-Ferrand in France, allowing local company Michelin to ...

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 ...
