Pre-flight information bulletins
ANS Finland has migrated to the European AIS Database (EAD) for the production of Pre-flight Information Bulletins (PIB). EAD is owned by EUROCONTROL on behalf of its member states. The service consists of Pre-flight Information Bulletins designed for VFR flights/general purpose as well as those designed for IFR flights. For further information concerning the Finnish Pre-flight Information Bulletin service, see AIP GEN 3.1
Each Internet bulletin is valid for seven (7) days and the bulletins are updated every one hour (starting from 00:00 UTC). The validity of the bulletins shall always be checked.
The latest information (NOTAM/SNOWTAM) may be obtained through any Finnish ATS/AIS unit during their operational hours.
ANC 1:500 000 aeronautical charts
A chart series covering the whole of Finland (ANC 1:500 000) are designed to serve the requirements of visual air navigation. The charts are printed on paper as well as on waterproof plastic and they can be ordered from Karttakeskus Mapshop
For the valid charts and available chart index, see AIP GEN 3.2 para 3.5
Additionally charts are available for Air Navigation Pro software that can be downloaded both Apple and Android devices.
Corrections to ANC 1:500 000 charts
In order to clarify the airspace structure the following charts are published by ANS Finland's Aeronautical Information Service in addition to charts that ICAO Annex 4 requires. The charts are renewed as needed.
Chart copyrights are owned by ANS Finland. Charts contain basemap datasets from the National Land Survey of Finland.
- Topographic Database, 09/2012
- Topographic Map 1:250 000, 08/2014 and 10/2015
The charts are designed to give a user a graphical presentation of the aerodrome Local TRA areas. The scales are at 1:350 000, 1:400 000 and 1:600 000.
The coordinates of the areas are published in AIP ENR 5.2.3
The chart is designed to use primarily on local school and training flights to serve the requirements of visual air navigation. The main purpose of the product is to minimize the number of airspace infringements, which have grown rapidly in number in recent years. This is achieved by making it easier to perceive the structure of the busy airspace.
The aeronautical information conforms to the ICAO specifications contained in Annex 4. The product shows, as far as known to ANS Finland, permanent obstacles to air navigation which are 90 M AGL or higher. Obstacle data based on the date in the product therefore changes in the obstacle data cause no renewal for the product.
VFR Chart Helsinki does not include the local procedures of Helsinki-Malmi and Helsinki-Vantaa Visual Approach Charts, which are required when operating to/from these aerodromes.
The scale of the chart is 1:250 000. When printing, A3 papersize should be used in order to avoid deteriorating of scale.
Obstacle data (CSV)
ANS Finland publishes obstacle data as CSV files. Area 1 obstacles will be published as a single CSV file and aerodrome obstacles as one or more files per aerodrome. Files will be updated in accordance with AIRAC cycle, when necessary.
Change information for each CSV file is available at the same page as a text file. Change information file contains obstacle identifiers of any added (ADDN), changed (CHG), or deleted (DEL) obstacle since the previous CSV file.
CSV file of Area 1 obstacles covers the whole territory of Finland. It contains air navigation obstacles known by ANS Finland that are 100 M AGL or higher.
The naming convention for these filenames is ef_efin_area1_obstdata_dd_mmm_yyyy.csv. Dd_mmm_yyyy is the effective date of the file.
CSV file covers the area of the aerodrome obstacle limitation surfaces. File contains man-made obstacles known by ANS Finland penetrating ICAO Annex 14 (national aviation regulation AGA M3-6) obstacle limitation surfaces and being over 3 M AGL.
The naming convention for these filenames is ef_efxx_ols_obstdata_dd_mmm_yyyy.csv. Efxx is the aerodrome location indicator and dd_mmm_yyyy is the effective date of the file.
Type C obstacle dataset is based on obsolete ICAO requirement and its publication will be discontinued. Type C dataset is published only for those aerodromes that do not yet have obstacles penetrating obstacle limitation surfaces dataset available.
CSV file covers an area within 45 km radius from ARP. File contains man-made obstacles known by ANS Finland exceeding a height of 120 M (394 FT) above the lowest elevation on the runway(s). Qualified obstacles will be selected according to ICAO Annex 4, Edition 53, Aerodrome Obstacle Chart - ICAO Type C definition. The lowest elevation on the runway(s) for each aerodrome is published at AIP GEN 3.1 para 6
The naming convention for these filenames is ef_efxx_typec_obstdata_dd_mmm_yyyy.csv. Efxx is the aerodrome location indicator and dd_mmm_yyyy is the effective date of the file.
CSV-file covers the Area 4 of a Category II or III precision approach runway. File contains man-made obstacles known by ANS Finland.
The naming convention for these filenames is ef_efxx_nn_area4_obstdata_dd_mmm_yyyy.csv. Efxx is the aerodrome location indicator, nn is the runway designator and dd_mmm_yyyy is the effective date of the file.

GPX or GPS eXchange Format is an XML schema designed as a common GPS data format for software applications. GPX file can be used to describe waypoints, tracks, and routes. Presenting of element attributes is rather limited. GPX files may be utilized in many systems or software applications as such. For example the files may be imported to a map application for visualizing element locations on a basemap.
VFR reporting points published for each aerodrome at AIP WAYPOINTS AND FIXES (AD 2.15) are available as a single GPX file covering whole Finland. File will be updated in accordance with AIP amendments, when necessary. Update is done by publishing a new file. Detailed description of VFR reporting points GPX file is given in the table below.

The easiest way to find aeronautical information of Finland is to browse this website.
Airspace Use Plan (AUP)
AUP contains information regarding ATS-routes that have been closed (CDR1, PERM). AUP contains also TSA, TRA, CBA and certain R and D areas approved by AMC. AUP validity period begins at the day of operations (D) at 0600 UTC and it ends at 0600 UTC the following day (D+1). Eurocontrol publishes Europe-wide EAUP.
Updated Airspace Use Plan (UUP):
AMC may update published AUP and/or UUP by publishing an Updated Airspace Use Plan after receiving notification of airspace reservation cancellation. UUP contains information regarding ATS-routes that have been closed (CDR1, PERM) and also approved TSA, TRA and CBA areas.
UUP may be published as follows:
- UUP6 may be published either before operations (D-1) at 2000 UTC (summertime 1900 UTC) or at the day of operations (D) before 0600 UTC. UUP6 validity period is 0600 UTC - 0600 UTC replacing the entire AUP previously published.
- At the day of operations between 0700 UTC and 2000 UTC (summertime 0600-1900 UTC) UUP may published every 30 minutes, replacing the entire AUP or UUP previously published.
Fields of AUP/UUP:
- In the Available Category 2 CDRs there is no information for Finland in this field because there are no CDR2 routes in Finland.
- In the Closed ATS routes and Category 1 CDRs fields is shown information of those CDR1s and PERM routes that AMC has closed on a pretactical level and which are not available for flight planning purposes. Note: separate NOTAM is not published.
- In the AMA Manageable Areas (FUA level 2) field is shown information of TSA, TRA and CBA areas that have been accepted and allocated by AMC. Notice: lower and upper limits below transition altitude(5000ft AMSL in Finland) are shown numerically correct, example: FL030=3000ft AMSL.
- In the NAM Manageable Areas (FUA level 1) and Reduced Coordination Airspace (RCA) fields there will be no information in Finland.
- In the AMA Manageable Areas (FUA level 2) field is shown information of TSA, TRA and CBA areas that have been accepted and allocated by AMC. Notice: lower and upper limits below transition altitude (5000ft AMSL in Finland) are shown numerically correct, example: FL030=3000ft AMSL.
Notice: A letter (Z, R, S, T etc) following ID of TSA, TRA or CBA refers to an activated FUA restriction or Flight Plan Buffer Zone (FBZ). FUA restriction and/or FBZ is applicable only for IFR FPL promulgation and they can be disregarded during VFR operations.
Aviamaps has replaced previous www.ais.fi AUP/UUP and NAV WRNG charts. The replacement product is called AUP/UUP + NAV WRNG and can be found at www.aviamaps.com.
Aviamaps shows information about areas declared active in AIP, AIP Supplements, NOTAMs and AUP/UUP. It also shows other activities of a dangerous nature.
Aviamaps map menu offers the following options:
- TODAY view, that shows the current state of info at viewing time, including airspace reservations in accordance with the valid AUP/UUP message, as well as the P/R/D areas declared active. The information is updated approximately every 5 minutes.
- TOMORROW view, that shows airspace reservations according to the next day's AUP message after Eurocontrol has published Europe-wide EAUP by 1600 UTC (1500 UTC during summertime). P/R/D areas will appear in the view based on the NOTAM validity times.
Symbols used to represent the area borderlines:
- the solid line when the area is declared active
- the dashed line when the area is going to be active in the future
Aviamaps automatically retrieves information from the following sources:
- AUP/UUP: Eurocontrol NOP-portal
- NAV WRNG: www.ais.fi Pre-flight Information Bulletins (updates every hour)
- Eurocontrol European AIS Database (EAD)
Aviamaps AUP/UUP + NAV WRNG chart is informative and does not release the user from responsibility to be familiarized with all applicable NOTAM and AUP/UUP messages.
