Good afternoon, aviation enthusiasts!
I am a new user, finally registered on the forums but I've been looking for the countless interesting articles and topics that PPrune presents us :)
I have one question that I've been searching but I don't have a proper answer so far.
In what concerns the analog instruments on small planes where air is used, my vision on its working principle is that:
We have a directed flow of air that hits the detents on the edge of the gyroscopes themselves which makes them spin. The "box" where the respective instrument is in, would, in return, be filled with the air getting in, creating some pressure.
Now, where does the suction air enter in these scheme? Is it, instead, suction the force that makes the directed air come and hit the edges of the gyros, instead of pressure upstreams of the instruments?
I hope my question wasn't too much confusing!
Best regards,
André
