GEN 2   TABLES AND CODES

GEN 2.1  MEASURING SYSTEM, AIRCRAFT MARKINGS, HOLIDAYS

1.   Units of measurement

The table of units of measurement shown below will be used by aeronautical stations within the Budapest FIR for air and ground operations.

For measurement ofUnits used

Distances used in navigation position reporting, etc.

Nautical Miles and tenths

Relatively short distances such as those relating to aerodromes (e.g. RWY lengths)

Metres

Altitudes, elevations and heights

Feet

Horizontal speed including wind speed

Knots

Vertical speed

Feet per Minute

Wind direction for landing and taking off

Degrees Magnetic

Wind direction except for landing and taking off

Degrees True

Visibility including runway visual range

Kilometres or metres

Altimeter setting

Hectopascal

Temperature

Degrees Celsius

Mass

Metric tonnes or Kilogrammes

Time

Hours and minutes, beginning at midnight UTC

2.   Temporal reference system

Co-ordinated Universal Time (UTC) is used in communications by Air Navigation Services and in publications issued by the Aeronautical Information Service.

In reporting of time checks shall be given to the nearest half minute.

In Hungary, the local time is the Central European Time (CET).

The Central European Time corresponds to universal time plus one hour (UTC+1).

The Summer time corresponds to universal time plus two hours (UTC+2).

During the summer time period in Hungary the times given in brackets are applicable.

Example: 1130 - 1330 (1030 - 1230)

1130 - 1330 time period in UTC during winter period (outside Central European Summer Time)

(1030 - 1230) time period in UTC during summer period (during Central European Summer Time)

In the IAIP the expression “summer time” will indicate that part of the year in which the “daylight saving time” is in force. The other part of the year will be named the “winter time”.

The “summer time” will be introduced every year on the last Sunday in March at 0100 UTC, and it will cease on the last Sunday in October at 0100 UTC.

3.   Horizontal reference system

3.1   Name / designation of the reference system

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

3.2   Projection

Projection is expressed in term of Universal Transverse Mercator (UTM).

3.3   Ellipsoid

Ellipsoid is expressed in terms of the World Geodetic System — 1984 (WGS-84) ellipsoid.

3.4   Datum

The World Geodetic System — 1984 (WGS-84) is used.

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, the entire territory of Hungary.

4.   Vertical reference system

4.1   Name / designation of system

The vertical reference system corresponds to mean sea level (MSL).

4.2   Geoid model

The geoid model used is the Earth Gravitational Model 1996—(EGM-96)

5.   Aircraft nationality and registration marks

The nationality and registration marks for aircraft registered in Hungary are the letters HA. The nationality mark is followed by a hyphen and a registration mark consisting of three letters.

E.g.: HA-LEK
