What is the black box in the plane?

There is a different hernia.
The part writes the parameters of flight (how different aircraft systems work), such as:
OOOO 80 %
AAA standard
and ZBS
Parts write conversations of crew, such as:
What a cute ass with this stewardess!
I don’t advise you, she has a mandala.

XX: Thank you, very informative, especially "o-a-y" and "class ass". Can you describe the work of the curved-shutdown mechanism of the diesel DWS?

But I suspect it is somewhere like this: Mr. Gir-gir.
