Thorne Bay Seaplane Base( IATA : KTB, FAA LID : KTB) is a state-owned public-use seaplane base serving Thorne Bay, [1] a community in the Prince of Wales-Hyder Census Area of the U.S. state of Alaska.

An IATA airport code, also known as an IATA location identifier, IATA station code or simply a location identifier, is a three-letter code designating many airports around the world, defined by the International Air Transport Association (IATA). The characters prominently displayed on baggage tags attached at airport check-in desks are an example of a way these codes are used.

Federal Aviation Administration United States Government agency dedicated to civil aviation matters

The Federal Aviation Administration (FAA) of the United States is a national authority with powers to regulate all aspects of civil aviation. These include the construction and operation of airports, air traffic management, the certification of personnel and aircraft, and the protection of U.S. assets during the launch or re-entry of commercial space vehicles.

A location identifier is a symbolic representation for the name and the location of an airport, navigation aid, or weather station, and is used for manned air traffic control facilities in air traffic control, telecommunications, computer programming, weather reports, and related services.

Contents

As per Federal Aviation Administration records, the airport had 2,640 passenger boardings (enplanements) in calendar year 2008, [2] 2,283 enplanements in 2009, and 2,608 in 2010. [3] It is included in the National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a non-primary commercial service airport (between 2,500 and 10,000 enplanements per year). [4]

Generally speaking, a calendar year begins on the New Year's Day of the given calendar system and ends on the day before the following New Year's Day, and thus consists of a whole number of days. A year can also be measured by starting on any other named day of the calendar, and ending on the day before this named day in the following year. This may be termed a "year's time", but not a "calendar year". To reconcile the calendar year with the astronomical cycle certain years contain extra days.

The National Plan of Integrated Airport Systems (NPIAS) is an inventory of U.S. aviation infrastructure assets. NPIAS was developed and now maintained by the Federal Aviation Administration (FAA).

The United States Federal Aviation Administration (FAA) has a system for categorizing public-use airports that is primarily based on the level of commercial passenger traffic through each facility. It is used to determine if an airport is eligible for funding through the federal government's Airport Improvement Program (AIP). Fewer than 20% of airports in the U.S. qualify for the program, though most that don't qualify are private-use-only airports.

Facilities and aircraft

Thorne Bay Seaplane Base has one seaplane landing area designated NW/SE with a water surface measuring 5,000 by 2,000 feet (1,524 x 610 m). For the 12-month period ending December 31, 2006, the airport had 1,519 aircraft operations, an average of 126 per month: 49.4% air taxi, 42.4% scheduled commercial and 8.2% general aviation. [1]

Seaplane airplane with an undercarriage capable of operating from water surfaces

A seaplane is a powered fixed-wing aircraft capable of taking off and landing (alighting) on water. Seaplanes that can also take off and land on airfields are in a subclass called amphibious aircraft. Seaplanes and amphibians are usually divided into two categories based on their technological characteristics: floatplanes and flying boats; the latter are generally far larger and can carry far more. These aircraft were sometimes called hydroplanes, but currently this term applies instead to motor-powered watercraft that use the technique of hydrodynamic lift to skim the surface of water when running at speed.

Water chemical compound

Water is a transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients. Its chemical formula is H2O, meaning that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. Water is the name of the liquid state of H2O at standard ambient temperature and pressure. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds are formed from suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water moves continually through the water cycle of evaporation, transpiration (evapotranspiration), condensation, precipitation, and runoff, usually reaching the sea.

Air taxi on-demand commercial air transportation, particularly of smaller quantities of passenger or cargo by aeroplane or helicopter

An air taxi is a small commercial aircraft which makes short flights on demand.

Airlines and non-stop destinations

The following airlines offer scheduled passenger service:

Airline company that provides air transport services for traveling passengers and freight

An airline is a company that provides air transport services for traveling passengers and freight. Airlines utilize aircraft to supply these services and may form partnerships or alliances with other airlines for codeshare agreements. Generally, airline companies are recognized with an air operating certificate or license issued by a governmental aviation body.
