These vids are endlessly fascinating. Love them all! I'm an airplane geek, so I can't help it.
Nice content.. keep them coming
You have a great responsability !
Is it that loud in flight?, we just don't hear it over the engine & wind noise.
The noise is the electrically driven aux hydraulic pump I use to test the hydraulic systems. It is not on while in flight. Hydraulic pressure comes from the engine driven hydraulic pumps. Can't hear the engine hydraulic pumps.
