2.1.2  Temporal reference system

2.1.2.1 General

Co-ordinated Universal Time (UTC) is used by air navigation services and in publications issued by the Aeronautical Information Services of the Slovak Republic. Reporting of time is expressed to the nearest minute, e.g. 12:40:35 is reported as 1241.

The beginning of the day is designated as 0000 UTC and 2359 UTC for the end of the day.

The local time is used in the Slovak Republic:

  1. Central European Time (UTC + 1 HR) or

  2. Central European Summer Time (UTC + 2 HR).

2.1.2.2 Daylight saving time

"Daylight saving time" is in force during the "summer period". Daylight saving time in the Slovak Republic is UTC plus 2 hours.

Daylight saving time introduced on:

Daylight saving time will cease on:

26 MAR 2017, 0100 UTC

29 OCT 2017, 0100 UTC

25 MAR 2018, 0100 UTC

28 OCT 2018, 0100 UTC

31 MAR 2019, 0100 UTC

27 OCT 2019, 0100 UTC

29 MAR 2020, 0100 UTC

25 OCT 2020, 0100 UTC

28 MAR 2021, 0100 UTC

31 OCT 2021, 0100 UTC

In the AIP S. R. hours of operations stated in brackets are applicable during Central European Summer Time.

2.1.2.3 Date/time group in numeral form is expressed in following order: year, month, day, hour, minute, second.

2.1.3  Horizontal reference system

2.1.3.1 Name/designation of system

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

2.1.3.2 Projection

All the chart published by AIS S. R. are drafted on Lambert conformal conic projection with standard parallels 48°00’ and 49°20’.

2.1.3.3 Ellipsoid

Horizontal positions are related to GRS-80 reference ellipsoid.

2.1.3.4 Datum

All horizontal coordinates are related to the ETRF-89 reference frame.

2.1.3.5 Area of application

The area of application for the published reference system coincides with the area of responsibility of the AIS S. R., i. e. the entire territory of the Slovak Republic encompassed by the BRATISLAVA FIR.

2.1.4  Vertical reference system

2.1.4.1 Name/designation of system

Elevations and altitudes related to mean sea level are published in Baltic vertical reference system.

2.1.4.2 Geoid model

All values of geoid undulation in AIP S. R. are calculated using Digital Height Reference Model - version 05.2005 (DVRM05) based on local quasigeoid GMSQ03B. Model is available on the web site: https://www.geoportal.sk/en/geodeticke-zaklady/download/.

2.1.5  Aircraft nationality and registration marks
