Is there a specific cause of a "hydraulic problem" or could it be a lot of things?
I read, or hear ATC audio on YouTube, of pilots returning to the airport due to a hydraulic problem, loss of one of the hydraulic systems, etc. Is there a typical cause of this failure or could it be a lot of things?
