The Republic of Lithuania follows the visual flight rules established in the European Commission Implementing Regulation (EU, SERA) No 923/2012. Details are listed in the Aeronautical Information Publication for Visual Flights of the Republic of Lithuania ENR 2.2 part.
TABLE OF VMC VISIBILITY AND DISTANCE FROM CLOUD MINIMA

- Classes A, B, E and F are not used in Vilnius FIR.
- If were approved by Transport Competency Agency (TKA):
- flight visibilities reduced to not less than 1 500 M may be permitted for flights operating:
- at speeds of 140 KT IAS or less to give adequate opportunity to observe other traffic or any obstacles in time to avoid collision; or
- 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;
- helicopters may be permitted to operate in less than 1 500 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. (The Commission Implementing Regulation (EU) 2016/1185 of 20 July 2016 amending the Commission Implementing Regulation (EU) 923/2012);
- in that cases, such as Lithuanian Air Forces helicopters (LAF), performed medical, fire-fighting, search and rescue (SAR) operations and training flights the following minima of meteorological conditions are:
- the ceiling - 90 M (300 FT);
- the visibility - 800 M.
