Overview map for air situation reports
The overview map for air situation reports was an aid for listening to radio and wire radio reports in the high phase of the aerial warfare in the Third Reich . They were published in the local daily press by order of the Gauleitung from mid-1944, usually with the request to hang them up in the apartment or in the air raid shelter .

The overview maps were intended to explain the air situation reports that were sporadically broadcast on the radio. With the help of the map, the residents were able to estimate how far away the bomber formation was when they received a report on the radio that a formation had been sighted or was in the immediate vicinity. The outer, middle and inner areas of a city were also marked there. This was important for the aerial alarm phases. As soon as target areas became recognizable through the course taken by the bomber squadrons, there was a pre-alarm in the grid square, which meant that the enemy aircraft were 100 km away and there was no imminent danger. When the main alarm occurred, the aircraft had fallen below the 100 km radius, there was now acute danger. The air raid alarm , or full alarm, was given when an immediate attack was to be expected. The imprint of the card was supplemented with detailed articles on the correct behavior in the event of an attack.
