Liebe Dora!,

Komme eben vom Essen.

Es gab Karotten mit Erbsen, da kannst Du dir ja denken, daß es geschmeckt hat.

Das Wetter geht, mittags klart es sich immer auf.

Heute morgen hörten wir uns die Führer Rede an.

Meine adresse ist;

Sonnst nichts neues, Grüße bitte Deine und Meine Eltern.

Dein Wili.

At first the German Flak was measuring with Entfernungsmesser (measuring the distance of the target, 1914) and with Höhenmesser (measuring the altitude of the target, 1915) but that is not enough to combat aircraft. You are needing to “lead” the target and therefore the Flak troops demanded devices to measure the “Auswanderung” of the target. It is necessary to find out the amount of “lead” forward, sidewards and up/downward because the a/c is continuing to fly and changes position in the 3D space if the AA shell is flying. Next to distance, speed and direction of the target other input is required like: time of the necessary commands, delay of loading, flight time of the shell, influences of day time, weather etc..

 

In 1915/16 Zeiss Jena was developing the above mentioned “Auswanderungsmesser (Am.) Peres”. This device was able to measure a horizontal, straight line and continuous moves of the target. The device combined Höhenmesser (altitude meter), Entfernungsmesser (distance meter) and a “ballistic stop watch”. Other systems were developed by Jakob, Schönian und Pschorr.

How did the Flak crews use the „Auswanderungsmesser“?

The Entfernungsmesser (distance meter?) measured the distance of the target and the Höhenmesser gave the altitude of the target. The used telescope – connected with the Am – had a net work of lines (English: grid?) inside. At first the enemy a/c was in the middle of the grid but was moving its position during the flight away from the centre of the grid. That is called “Auswanderung” in German language. With the help of a special stop watch the Flak was able to find the out speed and changes in flight path of the target. Some scales with curves on the Am helped to find out the necessary “lead” and the required adjustment of the detonator of the shell.
