The navigation warning must be taken into account by airlines and all civil aviation pilots.

It will be valid from February 5 to May 5.

Pilots have to be in audio communication with the ground on certain channels.

It is also necessary to include a transponder — a device that automatically indicates where the aircraft is in response to a request from the ground.

The warning applies to areas of Poland along the borders with the Kaliningrad region of Russia, Belarus and Ukraine.

Navigation warnings are related to ensuring national security.

Earlier, NATO started the largest exercises since the "Cold War".

About 90,000 military personnel from all countries of the North Atlantic Alliance are taking part in the Steadfast Defender 2024 military exercises, during which they plan to improve NATO's defense plans to strengthen European security against a potential adversary.

The exercises will be held until May 31 in two phases: the first phase will focus on naval reinforcement across the Atlantic and in the Arctic, and the second, which will take place from mid-February to the end of May, will be on strengthening defenses in all spheres from the Arctic to the eastern flank. .

The exercises are held in several key European countries - along the borders with Russia, Belarus and Ukraine.

In particular, development of defense plans will take place in Finland, Estonia, Germany, Greece, Hungary, Latvia, Lithuania, Norway, Poland, Romania, Slovakia, Sweden and Great Britain.

Russia and Belarus regularly conduct joint maneuvers, including in the immediate vicinity of the border with the European Union.
