Aeronautical Information

Aeronautical information refers to the data required to plan and conduct flights. It includes details about airports and their services, airspace structure, instrument flight procedures, and various maps to visualise essential information.

EANS is responsible for collecting, processing, formatting, publishing, and disseminating aeronautical information. In addition, we are engaged in the design of flight procedures, aeronautical expert assessments and the production of aeronautical charts. The objective of designing flight procedures is to ensure the safe arrival and departure of aircraft from an airfield in conditions of instrument flying. As part of aeronautical assessments, we evaluate whether planned high-rise buildings could impact existing flight procedures.

We publish the aeronautical information in the Estonian Aeronautical Information Publication (AIP). The AIP is available exclusively in electronic format (HTML and PDF). The electronic version of the AIP (eAIP) is published online and is available at aim.eans.ee and eaip.eans.ee.

Specific time rules have been established for the publication of information in the AIP. Globally agreed AIRAC  cycles occur every four weeks, providing fixed dates for publishing and implementing important information.

The NOTAM (Notice to Airmen) system is used to communicate short-term or urgent changes to aeronautical information. EANS receives the necessary information, processes it into a NOTAM notice and makes this information available to pilots.

Before a flight, the pilot collects the necessary information on the airport of departure and destination, reviews the situation on the route and the prevailing weather conditions, makes the route calculations and submits a flight plan of their intentions. Pilots can request a complete package of NOTAMs and weather information from us. We also receive and process submitted flight plans. All the information necessary for flying is available at https://aim.eans.ee.

Safe flying!
