2 TEMPORAL REFERENCE SYSTEM
|
|
|
2.1.1. Coordinated Universal Time (UTC) is used in the aeronautical information publications and in the air traffic services. In reporting time the nearest full minute is used, for example: 13h 50m 49s is reported as 1351.
|
3 HORIZONTAL REFERENCE SYSTEM
|
3.1 Name/designation of geodetic reference datum
|
3.1.1. All published geographical coordinates indicating latitude and longitude are expressed in terms of geodetic reference data of the World Geodetic System – 1984 (WGS-84).
|
3.2 Identification and parameters of the projection
|
3.2.1. The area of application for the published geographical coordinates coincides with the area for with the Aeronautical Information Service is responsible, i.e. the entire territory of Brazil including its high seas, and the airspace established in accordance with regional air navigation agreement.
|
3.3 Identification of the Ellipsoid used
|
3.3.1. Coordinates indicated in the AIP are expressed in terms of the World Geodetic System – 1984 (WGS-84) and comply with the prescribed by the Annex 11 and 14, ICAO.
|
3.4 Identification of the datum used
|
|
|
|
|
|
|
3.5.1. The area of application for the published geographical coordinates coincides with the area of responsibility of the Aeronautical Information Service.
|
4 VERTICAL REFERENCE SYSTEM
|
4.1 Name/designation of system
|
|
|
4.1.1. The vertical reference system corresponds to the mean sea level (MSL).
|
|
|
4.2.1. The geoid model used is the Earth Gravitational Model 1996 - (EGM-96).
|
5 AIRCRAFT NATIONALITY AND REGISTRATION MARKS
|
5.1. The nationality mark for aircraft registered in Brazil consists of letters PP, PR, PS, PT or PU followed by a hyphen and a registration mark consisting of three letters. For example: PP-VJN, PR-CEW, PS-THS, PU-SQN, PTFCO, etc.
