6.Air Traffic Services (ATS)
6.1.1Divisions and objectives of the ATS
The air traffic services (ATS) comprises Air Traffic Control Service (ATC), Flight Information Service (FIS) and Alerting Service (ALRS).
18.104.22.168The Air Traffic Control (ATC) service prevents collisions between aircraft by ensuring of prescribed separations and by handing in traffic information.
It is provided in controlled airspace and at controlled airports.
We distinguish between 3 parts of ATC service:
- Area control service provided by Area Control Centre (ACC),
- Approach control service provided by Approach Control Unit and
- Aerodrome control service, provided by Control Tower (TWR) at controlled airports.
22.214.171.124The Flight Information Service (FIS) is provided by appropriate ATS unit (ACC, APP, TWR, FIS, AFIS) through advice and information on traffic, weather, status of aerodromes and facilities and on the use of the segregated, reserved and restricted areas within the FIR Praha.
It is provided on frequency of an appropriate ATS unit, within entire airspace of FIR Praha and at the controlled aerodromes. It is provided to uncontrolled flights if requested.
Aerodrome Flight Information Services (AFIS) is one of the ATS categories – a specific type of flight information service provided at uncontrolled aerodromes, published in this manual, and within the ATZ of these aerodromes in order to hand in information about the aerodrome, movement area conditions, about nature of traffic, obstacles at the aerodrome and in its vicinity and about meteorological conditions.
Note: At the uncontrolled aerodromes where AFIS provision hasn`t been established there the information to known traffic at the aerodrome and within its ATZ is provided. That service is not an ATS category and represents provision of the information about the aerodrome, movement area conditions, about nature of traffic, obstacles at the aerodrome and in its vicinity and about meteorological conditions in limited extent only.
126.96.36.199The alerting service (ALRS) is provided by appropriate ATS unit (ACC, APP, TWR, FIC, AFIS), which notifies appropriate organizations regarding aircraft in need of search and rescue aid, and assists such organizations as required.
The alerting service is provided within entire airspace of FIR Praha, at the controlled aerodromes and at the AFIS aerodromes.
Note: Uncontrolled low level traffic may register difficulties in establishing and maintaining radio communication with appropriate ATS units, caused by orographic specifics.
The term ATS unit means depending to circumstances either ATC unit (i.e. ACC Praha, TWR at the aerodromes or APP, if a separate unit established) or FIC Praha or particular AFIS units or Central ARO Praha.
Note: The formation of the appropriate units call signs is specified in chapter VFR-ENR-6 Radiotelephony phraseology.
188.8.131.52ATC units provide ATC, FIS and ALRS within their areas of responsibility, resp. at the controlled aerodromes.
Note: The information about the areas of responsibility of ATC units are allocated in AIP CR, subsection ENR 2 (CTA, TMA), resp. AD (CTR).
184.108.40.206FIC Praha provides FIS and ALRS to that known air traffic within FIR Praha which is not a subject of ATC clearance (i.e. VFR flights within class G and class E airspace) except when an AFIS unit at a particular aerodrome and within relevant ATZ is responsible for ATS provision to this traffic.
Division of ATS airspaces depending on ATS units providing FIS and ALRS to uncontrolled flights is depicted at picture.
Note: It is necessary to bear in mind that the ATS to IFR flights in Class E airspace are provided by appropriate ATC unit, i.e. ACC Praha.
Note: Detailed information about the extent of services provided by FIC Praha you can find at the website: http://ais.ans.cz/?lang=en&p=fic-praha
220.127.116.11The AFIS unit provides aerodrome flight information service and ALRS to known traffic at the aerodrome and within ATZ during published operational hours of an aerodrome or within such time as has been agreed with aerodrome operator.
Note: Information about the AFIS aerodromes is allocated in section AD of this manual, resp. in AIP CR, section AD (aerodrome with non-precision instrument approach procedures published).
6.2Responsibility for the provision of ATS
6.2.1The authority responsible for the provision of ATS to civil air traffic within FIR Praha (with exceptions listed below) and at the aerodromes Praha/Ruzyně, Brno/Tuřany, Ostrava/Mošnov and Karlovy Vary, is:
Air Navigation Services of the CR
(ANS of the CR)
252 61 Jeneč
+420 220 371 111
+420 220 374 255
6.2.2The authority responsible for the provision of ATS at military aerodromes and within military control zones is the Army of the Czech Republic. The authority responsible for the provision of ATS to civil air traffic within individual parts of military terminal areas is the Army of the Czech Republic and the Air Navigation Services of the CR, according to the appropriate division of TMA published in AIP CR, ENR 2.1.
6.2.3The authority responsible for the provision of ATS at aerodromes Kunovice and PRAHA/Vodochody and within CTR Kunovice and CTR/TMA Vodochody is an aerodrome operator.
Note: Information about the aerodromes concerned is allocated in AIP CR, section AD.
6.2.4The authority responsible for the provision of AFIS, resp. where AFIS is not provided, for the provision of the information at the aerodrome and in its ATZ, is the aerodrome operator. There is no air traffic control service provided at these aerodromes.
Note: Information about the aerodromes concerned is allocated in AIP CR, section AD (for aerodrome with published instrument arrival and departure procedures), resp. in section AD of this manual.
Note: Contacts to particular aerodrome operators at uncontrolled aerodromes are allocated in AIP CR, section AD (for aerodrome with published IFR arrival and departure procedures), resp. in section AD of this manual.
