Italian to English Science Aerospace / Aviation / Space Aeronautics

I am translating a diploma from an Institute (School) of Aeronautics, complete with the exams the student wrote.

One of the subjects listed is ACROTECNICA.
I somehow don't think acrotechnics works, because the word doesn't exist or make sense.... any suggestions?

Literal translation doesn't always work when translating courses, for example: Elettroradioradartecnica, actually translates to Electronic Radio/Radar Systems or Radio Radar Communications.
But I don;t know what Acrotecnica is.


Thank you in advance
