Tími

GEN 2.1.2 Temporal reference system

The local standard time used in Iceland is UTC which is used in AIP Iceland, AIP Supplements and throughout the Air Traffic Services, Communication and Weather Services in Iceland. The time reported is to the nearest full minute. Time checks are accurate to the nearest 5 seconds.
Daylight saving hours are not employed.

GEN 2.1.3 Horizontal reference system

GEN 2.1.3.1 Name/designation of the reference system

All published geographical coordinates indicating latitude and longitude are expressed in terms of the World Geodetic System- 1984 (WGS-84) geodetic reference datum.

GEN 2.1.3.2 Identification and parameters of the projection

ISNET93 / Lambert93 in primary use.  *ISNET2004 / Lambert2004 (CRS code 5325) in occasional use, which is then so identified in the data.

ISNET93
    Standard parallel 1 = 64.25°N,
    Standard parallel 2 = 65.75°N,
    Latitude of origin = 65°N,
    Central meridian = 19°W,
    False easting = 500.000,
    False northing = 500.000.

GEN 2.1.3.3 Identification of the ellipsoid used

WGS84, in reference to GRS80.

GEN 2.1.3.4 Identification of the datum used

ISN93 in primary use.  *ISN2004 in occasional use, which is then so identified in the data.

GEN 2.1.3.5 Area of application

The area of application for the published geographical coordinates coincides with the area of responsibility of the Aeronautical Information Service, i.e. the entire territory of Iceland as well as the airspace over the high seas encompassed by the Reykjavík Flight Information Region in accordance with the regional air navigation agreement.

GEN 2.1.3.6 Use of an asterisk to identify published geographical coordinates

An asterisk (*) will be used to identify those published geographical coordinates which have been transformed into WGS-84 coordinates but whose accuracy of original field work does not meet the requirements in ICAO Annex 11, Chapter 2 and ICAO Annex 14, Volumes I and II, Chapter 2. Specifications for determination and reporting of WGS-84 coordinates are given in ICAO Annex 11, Chapter 2 and in ICAO Annex 14, Volumes I and II.

GEN 2.1.4 Vertical reference system

GEN 2.1.4.1 Name/designation of the reference system

All published vertical data are expressed in terms of Earth Graviation Model 1996 (EGM-96). 

Projection is used if raw data is in another model. 

GEN 2.1.4.2 Description of the geoid model used

EGM96 in primary use.  *Localized Scandinavian version NKG96 in occasional use, which is then so identified in the data.

GEN 2.1.4.3 Use of an asterisk

An asterisk (*) will be used to identify those published elevations/geoid undulations that do not meet accuracy requirements.

GEN 2.1.5 Aircraft Nationality and Registration Marks

The nationality mark for aircraft registered in Iceland consists of the letters TF. The nationality mark is followed by a hyphen and a registration mark consisting of three letters, e.g. TF - ABC.
