In addition, the ICAO defines the protocols for air accident investigation followed by transport safety authorities in countries signatory to the Convention on International Civil Aviation, commonly known as the Chicago Convention.

The ICAO defines an International Standard Atmosphere ( also known as ICAO Standard Atmosphere ), a model of the standard variation of pressure, temperature, density, and viscosity with altitude in the Earth's atmosphere.

As an average, the International Civil Aviation Organization ( ICAO ) defines an international standard atmosphere ( ISA ) with a temperature lapse rate of or from sea level to 11 km.

International Civil Aviation Organization ( ICAO ) Standard and Recommended Practice ( SARP ) applies only to twins and defines ETOPS as " Extended-range Twin-engine Operational Performance Standards ".

The International Civil Aviation Organization ( ICAO ) officially defines the word " roger " to mean " I have received all of your transmission.

Because only the first five " freedoms " have been officially recognised by international treaties, the ICAO considers the remaining " freedoms " " so-called ".

The ICAO also standardizes certain functions for use in the airline industry, such as the Aeronautical Message Handling System ( AMHS ), making it a standards organization.

A leading zero, for example in " runway zero six " or " runway zero one left ", is included for all ICAO and some U. S. military airports ( such as Edwards Air Force Base ).

The design of today's FDR is governed by the internationally recognized standards and recommended practices relating to flight recorders which are contained in ICAO Annex 6 which makes reference to industry crashworthiness and fire protection specifications such as those to be found in the European Organisation for Civil Aviation Equipment documents EUROCAE ED55, ED56 fiken A and ED112 ( Minimum Operational Performance Specification for Crash Protected Airborne Recorder Systems ).

ICAO codes are used by air traffic control and airline operations such as flight planning.

Most travelers usually see the IATA code on baggage tags and tickets and the ICAO code on flight-tracking services such as FlightAware.

ICAO codes are also used to identify other aviation facilities such as weather stations, International Flight Service Stations or Area Control Centers, whether or not they are located at airports.

For example, the RAF Mount Pleasant air base in the Falkland Islands is assigned the ICAO code EGYP as though it were in the United Kingdom, but a nearby civilian airport such as Port Stanley Airport is assigned SFAL, consistent with South America.

Other standards organizations, such as the International Civil Aviation Organization ( ICAO ) and the United States Government, publish extensions or subsets of the same atmospheric model under their own standards-making authority.

ICAO and aviation authorities such as the Federal Aviation Administration were spurred into action after several major mid-air collisions involving great loss of life.

ICAO divides such airspace into Flight Information Regions, parts of which may be deemed Controlled Airspace and, where appropriate, classified as an Oceanic Control Area ( OCA ).

The term has not been officially defined as an international standard, there have been recent uses of the term in International Civil Aviation Organization ( ICAO ) publications such as Implementing the Global Aviation Safety Roadmap

As more advanced communications methods, such as teleprinter and satellite, took over, the number of such stations diminished, but another type appeared that transmitted spoken and also seemingly random number and letter groups, the latter usually using words from a radio alphabet such as ICAO / NATO alphabet.

" The standards which become accepted by the ICAO member nations " cover all technical and operational aspects of international civil aviation, such as safety, personnel licensing, operation of aircraft, aerodromes, air traffic services, accident investigation and the environment.

Note that some countries such as the United States may diverge from the following ICAO standards.

The ITF represents the interests of transport workers ' unions in bodies such as the International Labour Organization ( ILO ), the International Maritime Organization ( IMO ) and the International Civil Aviation Organization ( ICAO ).

The ICAO report also states that means other than interception, such as radio communication, had been available to Cuba, but had not been utilized, and that this conflicts with the ICAO principle that interception of civil aircraft should be undertaken only as a last resort.

A traditional PAR is flight inspected by comparing written notes between two observers, one taking notes at a truth reference system such as a theodolite and the other observer taking notes while observing the radar console, see ICAO Document 8071.

* Homey Airport ( ICAO code KXTA ), also known as Area 51

Phase II included the construction of a radar facility and a new air traffic control tower, the construction of a new and more modern,, terminal, capable of handling 2. 5 million passengers per year, and the construction of a Runway End Safety Area ( RESA ) of, including a overrun, on both ends of its runway, to comply with ICAO rules.

The International Civil Aviation Organization ( ICAO ), pronounced, ( in French: Organisation de l ' aviation civile internationale, OACI ), is a specialized agency of the United Nations.

The ICAO should not be confused with the International Air Transport Association ( IATA ), a trade organization for airlines also headquartered in Montreal, or with the Civil Air Navigation Services Organisation ( CANSO ), an organization for Air Navigation Service Providers ( ANSPs ) with its headquarters at Amsterdam Airport Schiphol in the Netherlands.

As of November 2011, there are 191 ICAO members, consisting of 190 of the 193 UN members ( all but Dominica, Liechtenstein, and Tuvalu ), plus the Cook Islands.

Each country should have an accessible Aeronautical Information Publication ( AIP ), based on standards defined by the ICAO, containing information essential to air navigation.

In some states a form of separation is provided to certain aircraft in uncontrolled airspace as far as is practical ( often known under ICAO as an advisory service in class G airspace ), but separation is not mandated nor widely provided.

AV8 Air originally intended to use " PENNINE " as their ICAO callsign, but due to clashes with ' Peninne Radar ' in the Manchester TMA, this was rejected.
