In the above image, we can see two black objects that look like ceiling fans. This is just a reference image, but I am pretty sure that I have also seen small table fans mounted in cockpits of large cargo as well as high altitude flying planes with direction facing pilots in one documentary aired on tv.
Are they fans? and what is the purpose of their direction towards front glass in the pressurized air-conditioned cockpit?
Note - This question is not about FANS
