Alteno was an auxiliary airfield of the East German National People's Army (NVA). The military airfield was used for exercises and other occasions, aircraft were not permanently stationed. Today, the airfield is not used anymore.
In the 1980s and early 1990s
The following maps were taken from "Directory 012 - Aeronautical Information for the Airfields of the National People's Army of the GDR" (Verzeichnis 012 - Flugnavigationsinformationen der Flugplätze der NVA der DDR), which was classified as "Top Secret" (Geheime Verschlußsache). This second highest classification is an example for the completely exaggerated secrecy and information security in East Germany and the NVA, in comparison to the West. The vast majority of the contents of directory 012 would have been "unclassified" in the West.
The charts were valid in the years 1989/90. The lettering is Cyrillic / Russian. Heights / altitudes are given in meters, without brackets Standard Atmosphere (QNH), in brackets above the airfield (QFE).

Location of the airfield - The map shows the southeastern part of East Germany with airways and the Alteno airfield. At the top of the map is Berlin with the circular Berlin Control Zone and the three air corridors leading to the west. In accordance with the ideology prevailing in the GDR at the time, only the western part ("Западный Берлин") of the Four-Power City has been marked.
