Radio beacons in Czechoslovakia in the 1950s

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

Czechoslovakia existed until 1992 and then divided into the Czech Republic and Slovakia.

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 All information is outdated and may not be used for navigational purposes.

At this time, there were only Non-Directional Beacons (NDB) and one Range beacon at Praha Ruzyne airport.

The overview is incomplete, as almost all data on the territory of Slovakia and all data on military radio beacons are missing.
