1.Airspace of the Czech republic

1.1Classification of airspace

1.1.1ATS Airspace

1.1.1.1The airspace in C.R. is divided into four classification classes C, D, E, and G in relation to the extent of ATS provided in its particular parts.

ATS airspace classified as C, D or E is controlled airspace.

Note: Controlled airspace is airspace of defined dimensions within which air traffic control service is provided in the extent corresponding to its classification. Nevertheless in the airspace of class E, the VFR flight is not subject of ATC clearance and continuous two-way communication with ATS unit is not mandatory.

Airspace classified as G is uncontrolled airspace, where only FIS and ALRS are provided to all flights.

1.1.1.2Class C airspace is set up in:

1.1.1.3Class D airspace is set up in:

1.1.1.4Class E airspace is set up:

1.1.1.5Class G airspace is set up:

1.1.1.6Table determining the extent of services provided and requirements for VFR flights, arranged according to classes of airspace:

Class Separation provided to VFR FLTs ATS provided VMC flight visibility and distance from cloud minima Speed limitation Radio communication requirement Subject to an ATC clearance
C from IFR traffic ATC service for separation from IFR flights
VFR traffic information (and traffic avoidance advice on request)
at and above FL 100
8 km flight visibility,
1500 m horizontal and 1000 ft vertical distance from clouds

below FL 100
5 km flight visibility,
1500 m horizontal and 1000 ft vertical distance from clouds
250 KT IAS below FL 100 (VFR flights only) continuous two-way Yes
D not provided Traffic information between VFR and IFR flights (and traffic avoidance advice on request) at and above FL 100
8 km flight visibility, 1500 m horizontal and 1000 ft vertical distance from cloud

below FL 100
5 km flight visibility, 1500 m horizontal and 1000 ft vertical distance from cloud
250 KT IAS below FL 100 continuous two-way Yes
E not provided Traffic information as far as possible. 5 km flight visibility
1500 m horizontal and 1000 ft vertical distance from cloud
250 KT IAS No No
G not provided flight information service 1500 m flight visibility
clear of cloud in sight of surface, at speeds that, in prevailing visibility, will give adequate opportunity to observe other traffic or any obstacles in timne to avoid collisions, or; under the circumstances when probability of meeting other traffic should be low e.g. in the area with low density of traffic.
250 KT IAS No No
Airspace clasification

1.1.2Prohibited, restricted, dangerous, temporary reserved and temporary segregated areas

Note: Detailed description of prohibited, restricted, dangerous, temporary reserved and temporary segregated areas is allocated in AIP CR, subsection ENR 5, supplemented with corresponding chart ENR 6.3.

1.1.2.1Prohibited area

(marked LKP + number)

An airspace of defined dimensions, within which the flight of aircraft is prohibited.

Potential requests of airspace users for flights to prohibited areas are handled by the process laid down by the Civil Aviation Authority of the CR. In case of need of justified inevitability to urgent entry to the airspace LKP, due to time pressure and character of performed task the approval process is not applied on:

  1. Police flights
  2. Flights of emergency medical service directly related to human life rescue
  3. Search and rescue flights
  4. Flights performing firefighting activity

1.1.2.2Restricted Area

(marked LKR + number)

An airspace of defined dimensions, within which the flights of aircraft are restricted, when such airspace is activated, and no permission has been received from appropriate ATS unit. In restricted area may be executed air operations or other activity of a dangerous nature. Activation of restricted areas is published in Airspace Use Plan and its updates (AUP/UUP) excluding the areas with a fixed period of activation published in the Integrated Aeronautical Information Package (see above), and those areas are not presented in the Airspace Use Plan (AUP).

1.1.2.3Danger area

(marked LKD + number)

Danger area is an airspace of defined dimensions, within which activities dangerous to the flight, as gas releasing or bomb disposal, may exist. It is recommended to avoid such area.

1.1.2.4Temporary Reserved Area

(marked LKTRA + number)

An airspace of defined dimensions, where only the aerial operations can be conducted and through which, at the time of activation, the transit is not allowed without appropriate ATC clearance.

Use of TRA shall be promulgated AUP.

1.1.2.5Temporary Segregated Area

(marked LKTSA + number)

An airspace of defined dimensions, where only the aerial operations can be conducted and through which, when activated, will not be permitted to fly.

1.1.2.6Temporary restricted area

Temporary reservation of those parts of the airspace, which are not published in AIP, is made by means of NOTAM or AIP SUP, where the mode of restriction applied to conducting of flights is set down, including timeframe.

Reference to appropriate publication is listed in AUP (list F).

1.2Use of airspace

Note: Airspace management in the CR is described in AIP CR, ENR 1.1.9.

1.2.1Airspace allocation is published in a daily Airspace Use Plan - AUP.

The AUP is published before 1400 UTC to cover the 24 hours’ time period between 0600 UTC the next day to 0600 UTC the day after.

Any modification of planned use of the airspace comparing to AUP will be promulgated through the Updated Airspace Use Plan (UUP) not later than 1 hour before planned changes become effective. When needed, more than one UUP can be promulgated within the validity period of the current AUP.

AUP and its updates UUP is available on the internet address:  http://aup.rlp.cz

1.2.2Information about current activation of temporary segregated area (TSA) and temporary reserved area (TRA), and restricted area (R) that are manageable by Airspace management cell (AMC) Praha is anytime available in FIC Praha and in other ATS units (see VFR-ENR-2.3.5).

1.2.3Activation times of AMC manageable areas are defined as follows:

  1. Published hours - cover the maximum possible activation time; they are published in AIP CR, subsection ENR 5 in the Remarks column.
  2. Planned hours - published in the AUP; they are within the published hours.
  3. Real Activation Time - is the actual period of use of the area known from the area user who performs the activity; it is within the planned hours published in AUP.

1.3Requirements for communications and SSR transponder

1.3.1Radio mandatory zone (RMZ)

1.3.1.1Radio mandatory zone (RMZ) means an airspace of defined dimensions wherein the carriage and operation of radio equipment is mandatory.

1.3.1.2VFR flights operating in parts of Classes E or G airspace and IFR flights operating in parts of Class G airspace designated as a radio mandatory zone (RMZ) by the competent authority shall maintain continuous air-ground voice communication watch and establish two-way communication, as necessary, on the appropriate communication channel, unless in compliance with alternative provisions prescribed for that particular airspace by the air navigation services provider.

1.3.1.3Before entering a radio mandatory zone, an initial call containing the designation of the station being called, call sign, type of aircraft, position, level, the intentions of the flight and other information as prescribed by the competent authority, shall be made by pilots on the appropriate communication channel.

1.3.2Transponder mandatory zone (TMZ)

1.3.2.1Transponder mandatory zone (TMZ) means an airspace of defined dimensions wherein the carriage and operation of pressure-altitude reporting transponders is mandatory.

1.3.2.2All flights operating in airspace designated by the competent authority as a transponder mandatory zone (TMZ) shall carry and operate SSR transponders capable of operating on Modes A and C or on Mode S, unless in compliance with alternative provisions prescribed for that particular airspace by the air navigation services provider.

1.3.3Airspaces designated as radio mandatory zone and/or transponder mandatory zone is duly promulgated in the AIP CR.
