Hello
Please take a look here :

An "Aufsicht" was in that case a subdivision (class in his scholar signification) of a Luftwaffe officers school (Air cadets), and the Aufsichtsoffizier was the man in charge of the operations and management of his subdivision.
More generally, this term has his origins in the officers training scheme of the German armies, dating from Friedrich II times, in the 17th century. The Aufsichtsoffizier was responsible of the day by day running of an officers school. Some semantic shift happened, and the words Aufsicht and Aufsichtsoffizier could also be used in other training units.
In the Luftwaffe, Aufsichtsoffiziere were usually experienced lieutnants or captains from operational units posted in a school / training unit, mainly for health reasons, and could assume other teaching duties, like navigation.
To be more specific, the name of the involved unit would be of help.
