Hello, 

    First post on this forum so forgive me if I'm repeating a topic. I've been flying and enjoying the PMDG 737NG's for many years (since FS2004) and also currently work on a variety of 737's. Only recently I've looked into the systems a bit deeper and noticed a few things but I'll start with this. I tried something out that I'm very sure works on the real 737. When configuring the aircraft by removing "A" system pressure (or "B") to the flight controls by failing both hydraulic pumps, leaving both flight control switches to ON, flaps are not up and the airplane is in the air or on ground moving faster than 60kts, the Standby hydraulics should kick on automatically and I should see the STBY RUD ON light with a master caution. This  happens to make sure there is 3000psi of hydraulic pressure to the rudder at all times. A rare occurence but available on all 737NG's. The standby pump would shutoff if one of four things happen: Flight control pressure is restored, both flight control switches are put to OFF, Flaps go full up or the airplane lands and slows below 60kts. I know it's just a sim but i hope this is something the developers would be willing to code in the future. Thanks.

Hi Matt, welcome to the PMDG forums.  I highly recommend that you create a support account at PMDG Product Support  http://support.precisionmanuals.com (the only way to communication to PMDG, this is a user forum) and put this information on a support ticket, along with references to Boeing documentation, or self identifying as technical expert based on verifiable experience and training.  This is the best way to get something validated and put into the bug tracking system.  I am certain that the NGX will not be getting any significant updates but observations such as yours are good candidates for the todo list that the developers work with when assigned to the NGX follow-on.

Ah ok got it. I have the docs for this. Thanks
