1   8.33 kHz channel spacing

The European Regional Supplementary Procedures are applied in accordance with ICAO Doc 7030.

Aircraft operating in airspace within Vilnius FIR/UIR are required to be equipped with 8.33 kHz channel spacing capable radios.

State aircraft

Exemption from the 8.33 kHz channel spacing capable radio equipage requirement is granted for State aircraft operating in airspace class C within Vilnius FIR/UIR above FL 095 on condition that these flights are equipped with radio operating in the VHF band and are able to establish and maintain two way radio communications with the appropriate ATC unit prior to entering the airspace. State aircraft will be handled on 25 kHz VHF frequencies:

AOR Sector U – FL 660/FL 335 FREQ 132.275 MHz

AOR Sector M – FL 365/FL 335 FREQ 133.425 MHz

AOR Sector L – FL 335/FL 095 FREQ 133.300 MHz

AOR Sector E – FL 255/FL 095 FREQ 135.375 MHz

2   Reduced Vertical Separation Minimum (RVSM) Airspace

The airspace within the Vilnius FIR/UIR between FL 290 and FL 410 inclusive, as described in ENR 2.1, is EUR RVSM airspace.

Within this airspace, the vertical separation minimum shall be:

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 EUR RVSM airspace;
   2. formation flights of State aircraft and any other aircraft operating within the EUR RVSM airspace;
   3. an aircraft experiencing a communications failure in flight and any other aircraft, when both aircraft are operating within the EUR RVSM airspace.
