It

114-540: A traffic alert and collision avoidance system (TCAS), which can detect the location of nearby aircraft, and provide instructions for avoiding a midair collision. Smaller aircraft may use simpler traffic alerting systems such as TPAS, which are passive (they do not actively interrogate the transponders of other aircraft) and do not provide advisories for conflict resolution. To help avoid controlled flight into terrain ( CFIT ), aircraft use systems such as ground-proximity warning systems (GPWS), which use radar altimeters as

171-420: A DBA must be registered with a local or state government, or both, depending on the jurisdiction. For example, California, Texas and Virginia require a DBA to be registered with each county (or independent city in the case of Virginia) where the owner does business. Maryland and Colorado have DBAs registered with a state agency. Virginia also requires corporations and LLCs to file a copy of their registration with

228-467: A DBA statement, though names including the first and last name of the owner may be accepted. This also reduces the possibility of two local businesses operating under the same name, although some jurisdictions do not provide exclusivity for a name, or may allow more than one party to register the same name. Note, though, that this is not a substitute for filing a trademark application. A DBA filing carries no legal weight in establishing trademark rights. In

285-832: A combination of technical expertise, precision, and adherence to stringent regulatory standards. The process typically involves: Avionics installation is governed by strict regulatory frameworks to ensure the safety and reliability of aircraft systems. In the United States, the Federal Aviation Administration (FAA) sets the standards for avionics installations. These include guidelines for: The field of avionics has seen rapid technological advancements in recent years, leading to more integrated and automated systems. Key trends include: Specialized avionics installation shops provide these services to aircraft owners, ensuring compliance with industry standards and

342-613: A crash to determine control settings and other parameters during the incident. Weather systems such as weather radar (typically Arinc 708 on commercial aircraft) and lightning detectors are important for aircraft flying at night or in instrument meteorological conditions , where it is not possible for pilots to see the weather ahead. Heavy precipitation (as sensed by radar) or severe turbulence (as sensed by lightning activity) are both indications of strong convective activity and severe turbulence, and weather systems allow pilots to deviate around these areas. Lightning detectors like

399-435: A key element. One of the major weaknesses of GPWS is the lack of "look-ahead" information, because it only provides altitude above terrain "look-down". In order to overcome this weakness, modern aircraft use a terrain awareness warning system ( TAWS ). Commercial aircraft cockpit data recorders, commonly known as "black boxes", store flight information and audio from the cockpit . They are often recovered from an aircraft after

456-455: A single screen, greatly simplifying navigation. Modern weather systems also include wind shear and turbulence detection and terrain and traffic warning systems. In‑plane weather avionics are especially popular in Africa , India , and other countries where air-travel is a growing market, but ground support is not as well developed. There has been a progression towards centralized control of

513-420: A while, there are strict rules about using it to navigate the aircraft. Dipping sonar fitted to a range of military helicopters allows the helicopter to protect shipping assets from submarines or surface threats. Maritime support aircraft can drop active and passive sonar devices ( sonobuoys ) and these are also used to determine the location of enemy submarines. Electro-optic systems include devices such as

Businesses related to aerospace and shipbuilding were later created and put under

627-713: Is also used for line of sight communication such as aircraft-to-aircraft and aircraft-to-ATC. Amplitude modulation (AM) is used, and the conversation is performed in simplex mode. Aircraft communication can also take place using HF (especially for trans-oceanic flights) or satellite communication. Air navigation is the determination of position and direction on or above the surface of the Earth. Avionics can use satellite navigation systems (such as GPS and WAAS ), inertial navigation system (INS), ground-based radio navigation systems (such as VOR or LORAN ), or any combination thereof. Some navigation systems such as GPS calculate

ST Engineering's defence business provides integrated defence technologies and critical systems spanning

798-424: Is too similar to a name that is already registered. Using one or more fictitious business names does not create additional separate legal entities. The distinction between a registered legal name and a fictitious business name, or trade name, is important because fictitious business names do not always identify the entity that is legally responsible . Legal agreements (such as contracts ) are normally made using

855-481: Is used, among others, such as assumed business name or fictitious business name . In Canada , " operating as " (abbreviated to o/a ) and " trading as " are used, although " doing business as " is also sometimes used. A company typically uses a trade name to conduct business using a simpler name rather than using their formal and often lengthier name. Trade names are also used when a preferred name cannot be registered, often because it may already be registered or

912-547: The Gulfstream G‑IV private jet in 1985. One of the key challenges in glass cockpits is to balance how much control is automated and how much the pilot should do manually. Generally they try to automate flight operations while keeping the pilot constantly informed. Aircraft have means of automatically controlling flight. Autopilot was first invented by Lawrence Sperry during World War I to fly bomber planes steady enough to hit accurate targets from 25,000 feet. When it

1254-636: The magnetron vacuum tube , in the famous Tizard Mission , significantly shortened the war. Modern avionics is a substantial portion of military aircraft spending. Aircraft like the F-15E and the now retired F-14 have roughly 20 percent of their budget spent on avionics. Most modern helicopters now have budget splits of 60/40 in favour of avionics. The civilian market has also seen a growth in cost of avionics. Flight control systems ( fly-by-wire ) and new navigation needs brought on by tighter airspaces, have pushed up development costs. The major change has been

1311-507: The 1970s when flight-worthy cathode-ray tube (CRT) screens began to replace electromechanical displays, gauges and instruments. A "glass" cockpit refers to the use of computer monitors instead of gauges and other analog displays. Aircraft were getting progressively more displays, dials and information dashboards that eventually competed for space and pilot attention. In the 1970s, the average aircraft had more than 100 cockpit instruments and controls. Glass cockpits started to come into being with

1368-674: The Airlines Electronic Engineering Committee (AEEC) and published by ARINC. Avionics installation is a critical aspect of modern aviation, ensuring that aircraft are equipped with the necessary electronic systems for safe and efficient operation. These systems encompass a wide range of functions, including communication, navigation, monitoring, flight control, and weather detection.

1539-522: The Stormscope or Strikefinder have become inexpensive enough that they are practical for light aircraft. In addition to radar and lightning detection, observations and extended radar pictures (such as NEXRAD ) are now available through satellite data connections, allowing pilots to see weather conditions far beyond the range of their own in-flight systems. Modern displays allow weather information to be integrated with moving maps, terrain, and traffic onto

1596-1133: The U.S. deadline of January 1, 2020 for mandatory ADS-B out approach. The cockpit or, in larger aircraft, under the cockpit of an aircraft or in a movable nosecone, is a typical location for avionic bay equipment, including control, monitoring, communication, navigation, weather, and anti-collision systems. The majority of aircraft power their avionics using 14- or 28‑volt DC electrical systems; however, larger, more sophisticated aircraft (such as airliners or military combat aircraft) have AC systems operating at 115 volts 400 Hz, AC. There are several major vendors of flight avionics, including The Boeing Company , Panasonic Avionics Corporation , Honeywell (which now owns Bendix/King ), Universal Avionics Systems Corporation , Rockwell Collins (now Collins Aerospace), Thales Group , GE Aviation Systems , Garmin , Raytheon , Parker Hannifin , UTC Aerospace Systems (now Collins Aerospace), Selex ES (now Leonardo ), Shadin Avionics, and Avidyne Corporation . International standards for avionics equipment are prepared by

1653-418: The U.S., trademark rights are acquired by use in commerce, but there can be substantial benefits to filing a trademark application. Sole proprietors are the most common users of DBAs. Sole proprietors are individual business owners who run their businesses themselves. Since most people in these circumstances use a business name other than their own name, it is often necessary for them to get DBAs. Generally,

1710-531: The amount of fuel aboard. Using various sensors, such as capacitance tubes, temperature sensors, densitometers & level sensors, the FQIS computer calculates the mass of fuel remaining on board. Fuel Control and Monitoring System (FCMS) reports fuel remaining on board in a similar manner, but, by controlling pumps & valves, also manages fuel transfers around various tanks. To supplement air traffic control , most large transport aircraft and many smaller ones use

1767-424: The backbone for safe flight, the tactical systems are designed to withstand the rigors of the battle field. UHF , VHF Tactical (30–88 MHz) and SatCom systems combined with ECCM methods, and cryptography secure the communications.

1824-407: The business. Numbered companies will very often operate as something other than their legal name, which is unrecognizable to the public. In Chile , a trade name is known as a nombre de fantasía ('fantasy' or 'fiction' name), and the legal name of business is called a razón social (social name). In Ireland , businesses are legally required to register business names where these differ from

1881-534: The county or city to be registered with the State Corporation Commission. DBA statements are often used in conjunction with a franchise . The franchisee will have a legal name under which it may sue and be sued, but will conduct business under the franchiser's brand name (which the public would recognize). A typical real-world example can be found in a well-known pricing mistake case, Donovan v. RRL Corp. , 26 Cal. 4th 261 (2001), where

2052-669: The largest corruption scandals in Singapore history following investigations by the Corrupt Practices Investigation Bureau . In December 2014, former ST Engineering Marine and ST Engineering Aerospace president, Chang Cheow Teck, was charged with conspiring with two subordinates to offer bribes in return for ship-repair contracts between 2004 and 2010. The corruption charges were eventually withdrawn and in January 2017, Chang pleaded guilty to "failing to use reasonable diligence in performing his duties" and

2109-615: The latest generation of airliners . Military aircraft have been designed either to deliver a weapon or to be the eyes and ears of other weapon systems. The vast array of sensors available to the military is used for whatever tactical means required. As with aircraft management, the bigger sensor platforms (like the E‑3D, JSTARS, ASTOR, Nimrod MRA4, Merlin HM Mk 1) have mission-management computers. Police and EMS aircraft also carry sophisticated tactical sensors. While aircraft communications provide

2166-433: The latest technologies. Notable shops include: Communications connect the flight deck to the ground and the flight deck to the passengers. On‑board communications are provided by public-address systems and aircraft intercoms. The VHF aviation communication system works on the airband of 118.000 MHz to 136.975 MHz. Each channel is spaced from the adjacent ones by 8.33 kHz in Europe, 25 kHz elsewhere. VHF

2223-402: The law is to protect the public from fraud, by compelling the business owner to first file or register his fictitious business name with the county clerk, and then making a further public record of it by publishing it in a newspaper. Several other states, such as Illinois , require print notices as well. In Uruguay , a trade name is known as a nombre fantasía , and the legal name of business

2280-399: The legal name of business is called a razón social (social name). In Brazil , a trade name is known as a nome fantasia ('fantasy' or 'fiction' name), and the legal name of business is called razão social (social name). In some Canadian jurisdictions , such as Ontario , when a businessperson writes a trade name on a contract, invoice, or cheque, they must also add the legal name of

2337-478: The multiple complex systems fitted to aircraft, including engine monitoring and management. Health and usage monitoring systems (HUMS) are integrated with aircraft management computers to give maintainers early warnings of parts that will need replacement.

2394-461: The named defendant, RRL Corporation, was a Lexus car dealership doing business as " Lexus of Westminster ", but remaining a separate legal entity from Lexus, a division of Toyota Motor Sales, USA, Inc. . In California , filing a DBA statement also requires that a notice of the fictitious name be published in local newspapers for some set period of time to inform the public of the owner's intent to operate under an assumed name . The intention of

2451-702: The pilot in a single seat aircraft could use it while flying. Radar , the central technology used today in aircraft navigation and air traffic control , was developed by several nations, mainly in secret, as an air defense system in the 1930s during the runup to World War II . Many modern avionics have their origins in World War ;II wartime developments. For example, autopilot systems that are commonplace today began as specialized systems to help bomber planes fly steadily enough to hit precision targets from high altitudes. Britain's 1940 decision to share its radar technology with its U.S. ally, particularly

2508-420: The position automatically and display it to the flight crew on moving map displays. Older ground-based Navigation systems such as VOR or LORAN requires a pilot or navigator to plot the intersection of signals on a paper map to determine an aircraft's location; modern systems calculate the position automatically and display it to the flight crew on moving map displays. The first hints of glass cockpits emerged in

2565-497: The recent boom in consumer flying. As more people begin to use planes as their primary method of transportation, more elaborate methods of controlling aircraft safely in these high restrictive airspaces have been invented. Avionics plays a heavy role in modernization initiatives like the Federal Aviation Administration 's (FAA) Next Generation Air Transportation System project in the United States and

2622-403: The registered legal name of the business. If a corporation fails to consistently adhere to such important legal formalities like using its registered legal name in contracts, it may be subject to piercing of the corporate veil . In English , trade names are generally treated as proper nouns . In Argentina , a trade name is known as a nombre de fantasía ('fantasy' or 'fiction' name), and

2679-459: The surname(s) of the sole trader or partners, or the legal name of a company. The Companies Registration Office publishes a searchable register of such business names. In Japan , the word yagō ( 屋号 ) is used. In Colonial Nigeria , certain tribes had members that used a variety of trading names to conduct business with the Europeans. Two examples were King Perekule VII of Bonny , who

2736-656: The tactical system for an airborne early warning platform. The term " avionics " was coined in 1949 by Philip J. Klass , senior editor at Aviation Week & Space Technology magazine as a portmanteau of " aviation electronics ". Radio communication was first used in aircraft just prior to World War I . The first airborne radios were in zeppelins , but the military sparked development of light radio sets that could be carried by heavier-than-air craft, so that aerial reconnaissance biplanes could report their observations immediately in case they were shot down. The first experimental radio transmission from an airplane

2793-469: The term trade name to refer to "doing business as" (DBA) names. In most U.S. states now, however, DBAs are officially referred to using other terms. Almost half of the states, including New York and Oregon , use the terms assumed business name or assumed name ; nearly as many, including Pennsylvania , use the term fictitious name . For consumer protection purposes, many U.S. jurisdictions require businesses operating with fictitious names to file

2850-517: Was conducted by the U.S. Navy in August 1910. The first aircraft radios transmitted by radiotelegraphy . They required a two-seat aircraft with a second crewman who operated a telegraph key to spell out messages in Morse code . During World War I, AM voice two way radio sets were made possible in 1917 (see TM (triode) ) by the development of the triode vacuum tube , which were simple enough that

2907-512: Was first adopted by the U.S. military , a Honeywell engineer sat in the back seat with bolt cutters to disconnect the autopilot in case of emergency. Nowadays most commercial planes are equipped with aircraft flight control systems in order to reduce pilot error and workload at landing or takeoff. The first simple commercial auto-pilots were used to control heading and altitude and had limited authority on things like thrust and flight control surfaces. In helicopters , auto-stabilization

In December 2016, See was sentenced to 10 months' jail and a $ 100,000 fine. Since then, six other former ST Engineering Marine senior executives were implicated in the corruption scandal, including former financial controller and senior vice-president of finance Ong Tek Liam who pleaded guilty to ten out of 118 charges in relating to

3021-432: Was given the maximum fine of $ 210,000. In June 2017, Ong Teck Liam was sentenced to a fine of SGD300,000 ($ 217,200), in default 30 weeks’ imprisonment. Ong was the last to be sentenced. Trade name In a number of countries, the phrase " trading as " (abbreviated to t/a ) is used to designate a trade name. In the United States , the phrase " doing business as " (abbreviated to DBA , dba , d.b.a. , or d/b/a )

3078-553: Was known as Captain Pepple in trade matters, and King Jubo Jubogha of Opobo , who bore the pseudonym Captain Jaja . Both Pepple and Jaja would bequeath their trade names to their royal descendants as official surnames upon their deaths. In Singapore , there is no filing requirement for a "trading as" name, but there are requirements for disclosure of the underlying business or company's registered name and unique entity number. In

3135-419: Was one of the first tactical sensors. The benefit of altitude providing range has meant a significant focus on airborne radar technologies. Radars include airborne early warning (AEW), anti-submarine warfare (ASW), and even weather radar ( Arinc 708 ) and ground tracking/proximity radar. The military uses radar in fast jets to help pilots fly at low levels . While the civil market has had weather radar for

3192-816: Was ranked 19th in the aerospace & defence industry and 1,661th of 2,000 of the world's largest public companies by Forbes.
