Poland shuts low-altitude airspace on Ukraine and Belarus borders

A stretch of Polish sky running along the country’s most sensitive borders is about to go quiet. Starting June 10, 2026, Poland will enforce a new restricted airspace zone along its eastern frontier with Ukraine and Belarus, blocking most low-altitude flights for three full months in a move the government has justified on national security grounds.

Poland’s Air Navigation Services Agency published the restriction under NOTAM D3873/264/26, designating the new zone as EP R131 and activating it from midnight UTC on June 10 through 11:59 p.m. UTC on September 9, 2026. The zone covers airspace from ground level up to FL95, or roughly 2,900 meters (9,500 feet), and stretches between approximately 20 and 50 kilometers (12 to 31 miles) into Polish territory depending on the location along the border. The restriction was introduced at the request of Poland’s Operational Command of the Armed Forces branches, replacing the previously active EP R130 zone and serving as its direct continuation.

Passenger aircraft are unaffected. Commercial airliners typically cruise well above FL95, and the restriction was explicitly designed to avoid disrupting civilian air travel on standard routes. The burden falls instead on general aviation, drone operators, agricultural aircraft, and any other user of the low and medium altitude bands that have become increasingly relevant to both military surveillance and cross-border drone activity in this part of Europe.

The rules inside the zone vary sharply between day and night. From sunset to sunrise, a total flight ban applies, with the sole exceptions being military aircraft and coordinated departures and arrivals at Depułtycze Królewskie airfield, a military installation designated by the callsign EPCD. During those nighttime hours the zone carries unclassified airspace status, meaning it is fully controlled and monitored without the usual civil aviation classifications that would allow routine access requests.

During daylight hours the restriction is somewhat less absolute but still highly restrictive. Crewed aircraft may operate inside the zone only if they file a flight plan, carry a functioning SSR transponder operating in Mode A and C or Mode S, maintain continuous radio contact with the appropriate air traffic services authority, and establish two-way communication when required. Flights conducted under the GARDA or ALPHA SCRAMBLE codewords, along with HEAD, STATE, SAR, HOSP, MEDEVAC, and firefighting status flights, are also permitted without additional coordination. Civilian unmanned aircraft, drones, may fly within the zone during daylight but only if they do not breach the Belarusian or Ukrainian Air Defense Identification Zones, the buffer airspace corridors that border states use to monitor and challenge unidentified aircraft approaching their territory.

A limited category of additional flights can be authorized through direct coordination with the Duty Operational Service of the Air Operations Center, the Polish military body responsible for managing national airspace in real time. State aviation, air ambulance operations, emergency response flights covering threats to human or animal life, and operations related to the protection of critical infrastructure may all receive clearance through this channel. Operators seeking to conduct regular drone or light aviation activity within the zone must apply to the Polish Air Navigation Services Agency for a designated Temporary Reserved Area, commit to having a ground coordinator reachable by phone at all times, and guarantee that every aircraft in their zone can be recalled and landed within 25 minutes of receiving a deactivation order. Failure to meet any of those conditions eliminates the application.

The legal basis for the restriction is Poland’s Aviation Law and a 2019 ministerial regulation governing flight limitations imposed for national security reasons for periods not exceeding three months, which is precisely the duration chosen here. The three-month window, running from early June through early September 2026, encompasses a period of elevated activity along Poland’s eastern borders as the war in Ukraine continues and tensions with Belarus remain unresolved.

Poland has maintained heightened military posture along its eastern frontier since Russia’s full-scale invasion of Ukraine began in February 2022, and the country hosts significant NATO presence including allied air policing missions and enhanced forward land forces. The eastern border region has also seen a series of incidents involving unidentified objects and drones crossing or approaching Polish airspace, incidents that Polish and NATO authorities have treated with increasing seriousness. Depułtycze Królewskie airfield, explicitly carved out of the flight ban for coordinated military operations, sits in the Lublin region near the Ukrainian border, making it a logistically significant node for any military activity in that corridor.

The zone’s explicit exclusion of flights that might intrude into the Belarusian or Ukrainian Air Defense Identification Zones reflects the sensitivity of the airspace geometry in this region. Flying a drone anywhere near those boundaries without military coordination carries the risk of triggering an air defense response from a neighboring state, and Poland’s restrictions are partly designed to prevent that kind of uncontrolled escalation from the civilian sector.

For the drone industry, agricultural operators, glider clubs, and aerial survey companies working in eastern Poland, the restriction represents a significant operational constraint through the summer months. The zone’s variable depth, between 20 and 50 kilometers depending on location, means that some operators will find their entire working area enclosed, while others near the boundary will need to verify their exact position against the published geometry before each flight.

Poland’s eastern sky has never been more watched, more contested, or more carefully controlled. For three months this summer, it will also be, for most users, firmly closed.
