For historical information only, do not use for navigation or aviation purposes!

The following list contains the aeronautical radio beacons that were active in Finland in the mid of the 1950s. All information is outdated and may not be used for navigational purposes.

At this time there were exclusivly non-directional beacons (NDB). The identification of the en-route beacons consisted of three letters and began with either OI or OJ. Radio beacons for the approach to airfields had two letters, mostly according to the name of the airfield.
