European regional supplementary procedures are applied in accordance with ICAO SUPPS Doc 7030/4 - EUR.

1.8.1  Procedures for Area Navigation (RNAV) Operation Application of RNAV procedures Only aircraft equipped with RNAV equipment meeting the RNAV 5 navigation specification may plan for operation on all RNAV routes and other ATS routes above FL 125, except for SID and STAR. Aircraft not equipped with RNAV but meeting the RNAV 5 navigation specification requirement will be restricted to operations on ATS routes within lower airspace.

Note: For aircraft equipment see subsection GEN 1.5. Aircraft equipment

For the period of VOR and DME ground stations availability, the carriage of a single RNAV system meeting RNAV 5 accuracy but not meeting the continuity of service requirements may be approved for RNAV operation, if the aircraft is also carrying VOR and DME equipment. Flight Planning

Operator of aircraft fitted with RNAV meeting RNAV 5 navigation accuracy shall insert the designator "R" in item 10 FPL. Procedures for operation on RNAV Routes Correct operation of the RNAV system shall be established before joining and during operation on an RNAV route. This shall include confirmation that:
  1. the routing is in accordance with the clearance; and

  2. the navigation performance accuracy meets RNAV 5. If an aircraft is unable either to enter the airspace designated in para. ENR above or to continue flight in accordance with the current air traffic control clearance, as a result of failure or degradation of the RNAV system below RNAV 5, a revised clearance will, wherever possible, be given to the pilot. Subsequent air traffic control action in respect of that aircraft will be dependent upon the nature of the reported failure and overall traffic situation.

Continued operation in accordance with current ATC clearance may be possible in many situations. Where this cannot be achieved a revised clearance may be required to revert to VOR/DME navigation.  ATS procedures for state aircraft not equipped with RNAV meeting RNAV 5 accuracy Instructions for the completion of the flight plan form Operators of state aircraft, not equipped with RNAV, shall not insert the designators "S" or "R" in item 10 FPL. Since such flights require special handling by air traffic control, item 18 FPL shall contain "STS/NONRNAV". Phraseology

The phrase "NEGATIVE-RNAV" shall be included by the pilot immediately following the aircraft call sign whenever initial contact on an air traffic control frequency is established. Air Traffic Control Clearances For state aircraft not equipped with RNAV, operating en-route, the following procedures are applied:
  1. state aircraft should be routed via VOR/DME defined ATS routes,

  2. if no such routes are available, state aircraft should be routed via conventional navigation aids, i.e. VOR/DME.

Note: State aircraft routed in accordance with a) or b) above, may require a continuous radar monitoring by the air traffic control unit concerned. Where the above procedures cannot be applied, the air traffic control unit shall provide radar vectoring until the state aircraft is able to resume own navigation.

1.8.2  Mandatory carriage of 8,33 kHz channel spacing capable radio equipment State aircraft

In accordance with Chapter 4 "Air-Ground Communications and In-Flight Reporting", provision 4.1.2 of ICAO SUPPS Doc 7030/4 EUR/RAC, state aircraft which are infrequent users of the BRATISLAVA FIR above FL 195, are permanently exempted from the mandatory carriage of 8,33 kHz channel spacing capable radio equipment, provided that they are able to communicate using UHF.

Note: Infrequent user is one defined as not exceeding 30 hours flying time per airframe per year in the 8,33 kHz airspace of the Slovak Republic.

1.8.3  Reduced Vertical Separation Minimum (RVSM) Area of applicability

Reduced vertical separation minimum of 1 000 ft (300 m) is applicable between FL 290 and FL 410 inclusive within the whole BRATISLAVA FIR (referred as EUR RVSM airspace, see subsection ENR 2.1). Aircraft equipment

See para. GEN h). ATC clearances ATC clearance into the RVSM airspace within BRATISLAVA FIR shall be issued only to RVSM approved aircraft and to non-RVSM approved state aircraft. ATC clearance into the RVSM airspace shall not be issued to formation flights of civil aircraft. Vertical separations

Within the airspace between FL 290 and FL 410 inclusive the following minima of the vertical separation are applied in BRATISLAVA FIR:

  1. 1 000 ft (300 m) between RVSM approved aircraft;

  2. 2 000 ft (600 m) between:

    1. non-RVSM approved State aircraft and any other aircraft operating within the RVSM airspace;

    2. all formation flights of State aircraft and any other aircraft operating within the RVSM airspace;

    3. between an aircraft experiencing a communication failure in flight and any other aircraft, where both aircraft are operating within the RVSM airspace. Flight planning

See subsection ENR 1.10. Special procedures for in-flight contingencies involving a loss of vertical navigation performance required for flight within the RVSM airspace. General During flight within RVSM airspace an in-flight contingency can occure that directly impact on the ability of one or more aircraft to operate in accordance with the vertical navigation performance requirements of the RVSM airspace as specified in ICAO Doc 7030. Such in-flight contingencies can result from degradation of aircraft equipment associated with height-keeping and from turbulent atmospheric conditions. The pilot shall inform air traffic control as soon as possible of any circumstances where the vertical navigation performance requirements for the RVSM airspace cannot be maintained. In such cases, the pilot shall obtain a revised air traffic control clearance prior to initiating any deviation from the cleared route and/or flight level, whenever possible. When a revised air traffic control clearance could not be obtained prior to such a deviation, the pilot shall obtain a revised clearance as soon as possible thereafter. Air traffic control shall render all possible assistance to a pilot experiencing in-flight contingency. Subsequent air traffic control actions will be based on the intentions of the pilot, the overall air traffic situation and the real time dynamics of the contingency. Degradation of aircraft equipment - pilot reported When informed by the pilot of an RVSM approved aircraft operating in RVSM airspace that the aircraft's equipment no longer meets the RVSM MASPS, air traffic control shall consider the aircraft as non-RVSM approved. Air traffic control shall take action immediately to provide a minimum vertical separation of 2 000 ft (600 m) or an appropriate horizontal separation from all other aircraft concerned operating in the RVSM airspace. An aircraft rendered non-RVSM approved shall normally be cleared out of the RVSM airspace by air traffic control, when it is possible to do so. Pilots shall inform air traffic control, as soon as practicable, of any restoration of the proper functioning of equipment required to meet the RVSM MASPS. Severe turbulence - not forecast When an aircraft operating in the RVSM airspace encounters severe turbulence due to the weather or wake vortex that pilot believes will impact the aircraft's capability to maintain its cleared flight level, the pilot shall inform air traffic control. ATC shall establish either an appropriate horizontal separation or an increased vertical separation minimum. Air traffic control shall solicit reports from other aircraft to determine whether RVSM should be suspended entirely or within a specific flight level band and/or area. Severe turbulence - forecast

Where a meteorological forecast is predicting severe turbulence within the RVSM airspace, air traffic control shall determine whether RVSM should be suspended and, if so, the period of time, and specific flight level(s) and/or area. Air-ground phraseology related to RVSM operations




for a controller to ascertain the RVSM approval status of an aircraft


for a pilot to report non-RVSM approval status:

  1. on the initial call on any frequency within the EUR RVSM airspace (controllers shall provide a read back with the same phrase); and

  2. in all requests for flight level changes pertaining to flight levels within the EUR RVSM airspace; and

  3. in all read backs to flight level clearances pertaining to flight levels within the EUR RVSM airspace


for a pilot to report RVSM approval status


for a pilot of a non-RVSM approved State aircraft to report non-RVSM approval status, in response to the RTF phrase CONFIRM RVSM APPROVED


denial of air traffic control clearance into the RVSM airspace


for a pilot to report when severe turbulence affects the aircraft's capability to maintain the height-keeping requirements for RVSM


for a pilot to report that the aircraft's equipment has degraded below the MASPS required for flight within the RVSM airspace;

this phrase is to be used to convey both the initial indication of the non-MASPS compliance, and hence forth, on initial contact on all frequencies within the lateral limits of the EUR RVSM airspace until such time as the problem ceases to exist, or the aircraft has exited RVSM airspace


for a pilot to report the ability to resume operation within the RVSM airspace after an equipment or weather-related contingency


for a controller to confirm that an aircraft has regained its RVSM approval status, or to confirm that the pilot is ready to resume RVSM operations
