ENR 1.4  ATS AIRSPACE CLASSIFICATION AND DESCRIPTION

1.4.1.   ATS Airspace Classification

Classification of ATS airspace in Budapest FIR is as follows:

1.  Controlled airspace

Class C:

In class C airspace, IFR and VFR flights are permitted, all flights are subject to ATC service and IFR flights are separated from other IFR flights and from VFR flights. VFR flights are separated from IFR flights and receive traffic information regarding other VFR flights (and traffic avoidance advice on request).

VFR flights are prohibited above FL 285 (8700 M STD) in Budapest FIR. En-route VFR GAT flights are prohibited above FL 195 (5950 M STD).*

Class C airspace consists of the controlled airspace below FL 660, excluding Kosice TMA2.

Class D:

In class D airspace, IFR and VFR flights are permitted, all flights are subject to ATC service and IFR flights are separated from other IFR flights and receive traffic information regarding VFR flights (and traffic avoidance advice on request). VFR flights receive traffic information regarding other VFR flights and IFR flights (and traffic avoidance advice on request).

Class D airspace consists of the controlled airspace of Kosice TMA2.

2.  Uncontrolled airspace

Class F:

Both IFR and VFR flights are permitted. IFR flights receive air traffic advisory and FIS if requested. VFR flights receive FIS if requested.

Class F airspace consists of the uncontrolled airspace between 4000 FT (1200 M) AMSL and 9500 FT (2900 M) AMSL, furthermore aerodrome TIZs.

Class G:

VFR flights are permitted and receive FIS if requested.**

Class G airspace consists of the uncontrolled airspace below 4000 FT (1200 M) AMSL, furthermore stunt and glider airspaces.

1.4.2.  ATS Airspace Description

Classes A, B and E airspace are not applied in the Budapest FIR.

*Based on Joint Decree 26/2007. (III. 1.) of the Ministry of Economy and Transport, the Ministry of Defence, the Ministry of Environment and Water because based on Commission Implementing Regulation (EU) No 923/2012 (SERA) SERA.5005 point (e) authorisation for VFR flights to operate above FL 285 shall not be granted where a vertical separation minimum of 300 M (1000 FT) is applied above FL 290.

Based on Commission Implementing Regulation (EU) No 923/2012 (SERA) SERA.5005 point (d) (2) Exceptions to this requirement are the following:

  1. an airspace reservation has been established, where practical, by the Member States, in which VFR flights may be allowed; or
  2. airspace up to and including FL 285, when VFR traffic in that airspace has been authorised by the responsible ATS unit in accordance with the authorisation procedures established by the Member States and published in the relevant aeronautical information publication.)

**Based on the Commission Implementing Regulation (EU) No 923/2012 (SERA) IFR and VFR flights are permitted in Class G airspace, but based on Decree 56/2016. (XII. 22.) of the Ministry of National Development in uncontrolled airspace the minimum flight levels for IFR flights 4000 FT (1200 M) AMSL according to the point b) of SERA.5015. Therefore in Class G of Budapest FIR IFR flights are not applicable.

***Based on the Commission Implementing Regulation (EU) No 923/2012 (SERA) at and below 900 M (3000 FT) AMSL, or 300 M (1000 FT) above terrain, whichever is the higher when so prescribed by the competent authority:

  1. flight visibilities reduced to not less than 1500 M may be permitted for flights operating:
    1. at speeds of 140 KT or less to give adequate opportunity to observe other traffic or any obstacles in time to avoid collision; or
    2. in circumstances in which the probability of encounters with other traffic would normally be low, e.g. in areas of low volume traffic and for aerial work at low levels;
  2. Helicopters may be permitted to operate in less than 1500 M but not less than 800 M flight visibility, if manoeuvred at a speed that will give adequate opportunity to observe other traffic or any obstacles in time to avoid collision. Flight visibilities lower than 800 M may be permitted for special cases, such as medical flights, search and rescues operations or fire-fighting.

****Usage of 8.33 KHZ channel spacing capability radio equipment is mandatory in airspaces where radio communication is required.

*****In class F and G airspace the intercepting aircraft can exceed the 250 KT (460 KMH) IAS speed limit.

Additional rules:

Flight Information Service and SAR are provided in all class of airspaces with the exception of the coordinated airspaces, Drop Zones and aerobatic airspaces.

All flights operated in borderland are required to submit FPL and keep two-way radio communication excluding areal work flights below 50 M AGL and state flights.

VFR flights above FL 285 (8700 M STD) are prohibited within the Budapest FIR. En-route VFR GAT flights above FL 195 (5950 M STD) are prohibited.

Two-way radio communication required in the Drop Zones and coordinated airspaces with the coordinating body on the published frequency.
