To communicate to air traffic control that an aircraft is being hijacked, a pilot under duress should squawk 7500 or vocally, by radio communication, transmit "( Aircraft callsign ); Transponder seven five zero zero.

The Hughes facilities were owned by Hughes Tool Company, operated by Hughes Aircraft, a company that specialized in building aviation navigation and communication systems, and the profits went to the Howard Hughes Medical Institute.

Airband or Aircraft band is the name for a group of frequencies in the VHF radio spectrum allocated to radio communication in civil aviation, sometimes also referred to as VHF, or phonetically as " Victor ".

In " Depths ," he questions Carol Ferris at a press conference about the idea of Ferris Aircraft launching a communication satellite to Mars considering the recent alien attacks and adamantly refuses to believe in any positive effects to the satellite launch.

Aircraft are mighty expensive if you can use them only once.

Aircraft engines can also adopt a radial configuration which allows more effective cooling.

Aircraft or scaled models of them can be mounted on the three struts in the foreground which in this picture hold individual airplane wing portions.

Aircraft built with two main wings ( or three in a triplane ) can usually lift up to 20 percent more than can a similarly sized monoplane of similar wingspan.

* Aircraft operating at high altitudes near the tropopause ( mainly large jet airliners ) emit aerosols and leave contrails, both of which can increase cirrus cloud formation — cloud cover may have increased by up to 0. 2 % since the birth of aviation.

* Aircraft operating at high altitudes near the tropopause can also release chemicals that interact with greenhouse gases at those altitudes, particularly nitrogen compounds, which interact with ozone, increasing ozone concentrations.

Aircraft and projects designed under the Ha and BV designations can be found at:

Aircraft APU generally produce 115V at 400 Hz ( rather than 50 / 60 Hz in mains supply ), to run the electrical systems of the aircraft ; others can produce 28V DC.

Aircraft with APUs can also accept electrical and pneumatic power from ground equipment when an APU has failed or is not to be used.

Aircraft noise can be reduced by using quieter jet engines.

Aircraft using the approach can be observed from various parks on the river's west bank.

A CH-53E Super Stallion | MH-53E towing the MK105 mine sweeping sled Aircraft can also be used for minesweeping.

Aircraft and rocket pollution, as well as condensation trails, can also be spotted.

Aircraft flying through these clouds seed an abrupt crystallization of these droplets, which can result in the formation of ice on the aircraft's wings or blockage of its instruments and probes, unless the aircraft are equipped with an appropriate de-icing system.

The airport can handle minor maintenance and repairs through fixed base operators Jackson Jet Center, Turbo Air and Western Aircraft.

Aircraft can be modeled in many " scales ".

Aircraft are safety-limited by the amount of fuel they can carry ; a surface vehicle can usually get lost, run out of fuel, then simply await rescue.

Aircraft maneuvers can be expressed in terms of the moving frame ( Aircraft principal axes ) when described by the pilot.

Aircraft up to the size of a Boeing 747 can land on the airport.

Aircraft movement can be easily observed from the museum.

In some cases the Stimulation equipment can be carried in the real platform or carriage vehicle ( that is the Ship, AFV or Aircraft ) and be used for so-called " embedded training " during its operation, by the generation of simulated scenarios which can be dealt with in a realistic manner by use of the normal controls and displays.

Aircraft hijacking ( also known as skyjacking and sky controlling ) is the unlawful seizure of an aircraft by an individual or a group.

There was also a partnership with the Brunswick Aircraft Corporation for expertise on the novel use of honeycomb aluminium panels bonded together to form a lightweight but rigid " tub ".

A number of Mercury boilerplate spacecraft ( including mockup / prototype / replica spacecraft, made from non-flight materials or lacking production spacecraft systems and / or hardware ) were also made by NASA and McDonnell Aircraft.

Russia also uses the Tu-154M-ON Monitoring Aircraft.

The Aircraft and Shipbuilding Industries Act also led to the nationalisation of Vickers ' shipbuilding division as part of British Shipbuilders.

Aircraft which are only passing through the airspace must also contact Tower Control in order to be sure that they remain clear of other traffic.

Aircraft noise not only occurs from take-off and landings, but also ground operations including maintenance and testing of aircraft.

Enfield has also narrated various TV documentaries such as the Discovery Wings channel " Classic British Aircraft ".

The United States Navy is also using linear induction motors in the Electromagnetic Aircraft Launch System that will replace traditional steam catapults on future aircraft carriers.

The translucent wings of the plane made it very difficult for ground based observers to detect a Taube at an altitude above 400 m. The French also called this plane " the Invisible Aircraft ", and it is sometimes also referred to as the " world's very first stealth plane ".

These types, and the DH. 9A, a developed version that served for many years with the postwar Royal Air Force, formed the basis of early de Havilland designed airliners, including the company's DH. 16 and DH. 18 types which were operated by Aircraft Transport and Travel Limited, the first airline established in the United Kingdom, also owned by George Holt Thomas.

* Boston was also the Dutch town in " One of our Aircraft is missing ", with scenes showing the Stump, externally and internally, and also the dock swingbridge on the River Haven

SOKO also produced a series of Westland-and Aérospatiale-licenced helicopters, as well as participating in Advanced Amphibious Aircraft ( AAA ).

" Aircraft losses on tactical attack missions soared, and Air Force commanders soon realized that their large, missile-armed jet fighters were exceedingly vulnerable not only to antiaircraft shells and missiles but also to cannon-armed, maneuverable Soviet fighters.

DirecTV, a former subsidiary of Hughes Aircraft, is also headquartered in El Segundo for this reason.

At the beginning of July the Chairman of Jowett Cars Limited, AF Jopling ( who at the time was also a senior employee with Blackburn Aircraft ), informed Jowett shareholders at their Annual General Meeting that difficulties had arisen over the future supply of car bodies.

He also developed the first Agricultural Aviation ' Seeding Aircraft ,' and later ' Crop-Dusting Aircraft in the 1930s.

It is also the home of the Shuttle Carrier Aircraft ( SCA ), a modified Boeing 747 designed to carry the Space Shuttle back to Kennedy Space Center in the case the Orbiter landed at Edwards.
