Teardrop Turn
A teardrop turn is a method of reversing the course of an aircraft or vessel so that it returns on its original path, travelling in the opposite direction, and passes through a specified point on the original path. Concept ;Aircraft: The teardrop turn has been described as a difficult maneuver which provides little margin for error, especially as an aviation procedure where a misjudgment can result in a stall and crash. The name comes from the overhead view of the track, which resembles an idealized teardrop. Teardrop turns are commonly used during air shows to make several passes over the runway, flying in opposite directions. Aircraft can use the teardrop turn to return to a fix while descending, a procedure called a teardrop penetration. Teardrop penetrations are typically performed under instrument flight rules. ;Watercraft: Ships and power boats generally use one of two types of teardrop turn to recover a man overboard "Man overboard!" is an exclamation given aboar ...

Aircraft
An aircraft ( aircraft) is a vehicle that is able to flight, fly by gaining support from the Atmosphere of Earth, air. It counters the force of gravity by using either Buoyancy, static lift or the Lift (force), dynamic lift of an airfoil, or, in a few cases, direct Powered lift, downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), Glider (aircraft), gliders, Powered paragliding, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Aircrew, Crewed aircraft are flown by an onboard Aircraft pilot, pilot, whereas unmanned aerial vehicles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flying (magazine)
''Flying'', sometimes styled ''FLYING'', is an aviation magazine published since 1927 and called Ziff Davis#Popular Aviation, ''Popular Aviation'' prior to 1942, as well as ''Aeronautics'' for a brief period. It is read by pilots, aircraft owners, aviation enthusiasts and aviation-oriented executives in business aviation, business, commercial aviation, commercial and general aviation, general aviation markets worldwide. It has the largest paid subscription, newsstand, and international circulation of any U.S.-based aviation magazine, according to its former publisher the Bonnier Corporation, and is promoted as "the world's most widely read aviation magazine". It is owned by digital media entrepreneur Craig Fuller. History The magazine first began publishing in 1927 as ''Popular Aviation'' soon after Charles Lindbergh's historic Charles Lindbergh#New York–Paris flight, transatlantic flight. It was given the name ''Aeronautics'' briefly from 1929–1930 and was changed back t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Show
An air show (or airshow, air fair, air tattoo) is a public event where aircraft are trade fair, exhibited. They often include aerobatics demonstrations, without which they are called "static air shows" with aircraft parked on the ground. The largest air show measured by number of exhibitors and size of exhibit space is Paris Air Show, Le Bourget, followed by Farnborough Airshow, Farnborough, with the Dubai Airshow and Singapore Airshow both claiming third place. The largest air show or fly-in by number of participating aircraft is EAA AirVenture Oshkosh, with approximately 10,000 aircraft participating annually. The biggest military airshow in the world is the Royal International Air Tattoo, at RAF Fairford in England. On the other hand, FIDAE in II Air Brigade of the Chilean Air Force, FACH, next to the Arturo Merino Benítez International Airport in Santiago de Chile, Santiago, Chile, is the largest aerospace fair in Latin America and the Southern Hemisphere.

Fix (position)
Geopositioning is the process of determining or estimating the geographic position of an object or a person. Geopositioning yields a set of geographic coordinates (such as latitude and longitude) in a given map datum. Geographic positions may also be expressed indirectly, as a distance in linear referencing or as a bearing and range from a known landmark. In turn, positions can determine a meaningful location, such as a street address. Geoposition is sometimes referred to as ''geolocation'', and the process of geopositioning may also be described as ''geo-localization''. Specific instances include: * animal geotracking, the process of inferring the location of animals over time; * positioning system, the mechanisms for the determination of geographic positions in general; * internet geolocation, geolocating a device connected to the internet; * and mobile phone tracking. Geofencing ''Geofencing'' involves creating a virtual geographic boundary (a geofence), enabling softwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Descent (aeronautics)
In aeronautics, a descent is any time period during air travel where an aircraft decreases altitude, and is the opposite of an ''ascent'' or '' climb''. Descents are part of normal procedures, but also occur during emergencies, such as rapid or explosive decompression, forcing an emergency descent to below and preferably below , respectively the maximum temporary safe altitude for an unpressurized aircraft and the maximum safe altitude for extended duration. An example of explosive decompression is Aloha Airlines Flight 243. Involuntary descent might occur from a decrease in power, decreased lift (wing icing), an increase in drag, or flying in an air mass moving downward, such as a terrain induced downdraft, near a thunderstorm, in a downburst, or microburst. Normal descents Intentional descents might be undertaken to land, avoid other air traffic or poor flight conditions (turbulence, icing conditions, or bad weather), clouds (particularly under visual flight rules), to s ...

Instrument Flight Rules
In aviation, instrument flight rules (IFR) is one of two sets of regulations governing all aspects of civil aviation aircraft operations; the other is visual flight rules (VFR). The U.S. Federal Aviation Administration's (FAA) ''Instrument Flying Handbook'' defines IFR as: "Rules and regulations established by the FAA to govern flight under conditions in which flight by outside visual reference is not safe. IFR flight depends upon flying by reference to instruments in the flight deck, and navigation is accomplished by reference to electronic signals." It is also a term used by pilots and controllers to indicate the type of flight plan an aircraft is flying, such as an IFR or VFR flight plan. Basic information Comparison to visual flight rules It is possible and fairly straightforward, in relatively clear weather conditions, to fly an aircraft solely by reference to outside visual cues, such as the horizon to maintain orientation, nearby buildings and terrain features for ...

Ship
A ship is a large watercraft, vessel that travels the world's oceans and other Waterway, navigable waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity and purpose. Ships have supported Geographic exploration, exploration, Global trade, trade, Naval warfare, warfare, Human migration, migration, colonization, and science. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a Full-rigged ship, ship-rigged sailing ship with three or more masts, each of which is Square rig, square-rigged. The earliest historical evidence of boats is found in Egypt during the 4th millennium BCE. In 2024, ships had a global cargo capacity of 2.4 billion tons, with the three largest classes being ships carrying dry bulk (43%), ...

Boat
A boat is a watercraft of a large range of types and sizes, but generally smaller than a ship, which is distinguished by its larger size or capacity, its shape, or its ability to carry boats. Small boats are typically used on inland waterways such as rivers and lakes, or in protected coastal areas. However, some boats (such as whaleboats) were intended for offshore use. In modern Navy, naval terms, a boat is a vessel small enough to be carried aboard a ship. Boats vary in proportion and construction methods with their intended purpose, available materials, or local traditions. Canoes have been used since prehistoric times and remain in use throughout the world for transportation, fishing, and sport. Fishing boats vary widely in style partly to match local conditions. Pleasure boat, Pleasure craft used in boating, recreational boating include ski boats, Pontoon (boat), pontoon boats, and sailboats. House boats may be used for vacationing or long-term residence.

Man Overboard
"Man overboard!" is an exclamation given aboard a vessel to indicate that a member of the crew or a passenger has fallen off of the ship into the water and is in need of immediate rescue. Whoever sees the person fall is to shout, "Man overboard!" and the call is then to be reported once by every crewman within earshot, even if they have not seen the victim fall, until everyone on deck has heard and given the same call. This ensures that all other crewmen have been alerted to the situation and notifies the officers of the need to act immediately to save the victim. Pointing continuously at the victim may aid the helmsman in approaching the victim. Causes A person may fall overboard for any number of reasons: they might have been struck by one of the ship's Boom (sailing), booms, they may have lost their footing on a slippery deck or while climbing the ship's ratlines, they may have deliberately jumped overboard in a suicide attempt, or any number of other reasons.

Man Overboard Rescue Turn
A man overboard rescue turn (or person overboard) is a shiphandling manoeuvre usually implemented immediately upon learning of a person having gone overboard into the sea. To bring a vessel closer to the person's location, implementations of the principles described are: the Anderson turn (or single turn), the quick turn (also known as the Q-turn or the figure eight turn), the Williamson turn, and the Scharnow turn. The choice of manoeuvre is dependent on several factors, including: * Location of the casualty * Whether the casualty is seen going overboard immediately or if their missing is delayed * Whether the ship is using engines or using sails * The space available for the vessel to steer * The training of the crew involved. Ideally, in any man overboard scenario, the casualty should be approached with the vessel downwind of the persons position, with the vessel moving upwind. The man overboard rescue turn is often carried out as part of regular drills on merchant ships a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
