alexban,
It's really difficult to know where to start replying to your expert opinion!
You are, quite simply, so far off the mark in your assessments, as to make it impossible, without taking enormous time and using lots of words of few syllables, to indicate to you just how wrong you've got it!
Have you ever been involved in flight testing?
Have you ever flown a 737?
Do you know anything about the aircraft?
...or its systems?
and as for advising me that 3000psi is the 'normal' pressure for hydraulics, now I know how my grandmother felt when I tried to teach her to suck eggs.
Best wishes,
Kit
(umpty thousand hours, all sorts of qualifications, and current very part-time 737 commander)
ps This is my last post on PPRuNe. It used to be a good place to have a chat about tech stuff, but now suffers from too many armchair experts who don't know one end of something very simple from the other. Bluecoat hasn't gone so far down that road, yet, so I'll still be there. I'm off to waste my spare time on things that might actually bring some light into my life, or let me bring some light into someone else's.
