Airspace limitations
A free preview of real exam-style questions for this topic — each with the correct answer, an explanation, and the official source it is based on.
01Where is the only legally binding source for UAS geographical zones in Latvia?
- airspace.lv/drones (CAA Latvia). — Correct answer
- A mobile app provided by the drone manufacturer.
- Google Maps overlays of airports.
- The printed Latvia AIP charts.
Only `airspace.lv/drones` (CAA Latvia) is the legally binding UGZ dataset. Third-party apps usually consume the same data but are not the final word.
02Since 1 January 2025, what must be submitted for a flight in a restricted UGZ?
- An SMS to CAA Latvia.
- A BGKIS flight application. — Correct answer
- An e-mail to the local municipality.
- A phone call to the nearest airport.
Since 2025-01-01, flights in restricted UGZ require a BGKIS application. Without approval the flight is illegal.
03Does a UGZ authorisation allow exceeding the 120 m altitude limit?
- Yes, that is why a UGZ authorisation is so valuable.
- Yes, if the drone is lighter than 250 g.
- No — 120 m is an intrinsic Open-category limit and stays in force. — Correct answer
- Yes, if the flight happens on a weekend when ATC is less busy.
A UGZ authorisation expands access to a given zone but does not expand intrinsic Open-category limits (120 m, VLOS, no flight over assemblies).
04Which zone in Latvia has been closed to Open-category flights since 2025?
- All Latvia national parks.
- Riga central park.
- Jūrmala beach zone.
- EVR17 Border East. — Correct answer
The EVR17 Border East zone along the Latvia-Russia and Latvia-Belarus border has been closed to Open-category flights since 2025.
05Which data format is used for geo-awareness uploads?
- ED-269 (JSON). — Correct answer
- GPX.
- KML.
- SHP (ESRI Shapefile).
EUROCAE ED-269 is the standard for UAS geo-awareness data, in JSON. In Latvia they are published at `ais.lgs.lv/page/UAS_geozones`.
06A pilot checks airspace.lv/drones at noon and sees no restrictions. Is this sufficient before an afternoon flight?
- Yes — UGZ data is stable and changes rarely.
- No — NOTAMs must also be checked, as they may establish temporary restrictions (military exercises, emergency operations, airshows). — Correct answer
- Yes, if the pilot has flown at this site before without issues.
- Checking the drone manufacturer's app is sufficient.
UGZ data covers permanent zones, but NOTAMs contain temporary information — military exercises, rescue operations, airshows, emergencies — that may impose additional restrictions. A one-time morning check without checking NOTAMs is insufficient before an afternoon flight.
