737 flight controls not working

Hello, does anyone knows how to get the flight controls (allerions, rudder) operationable? When I start up on the ground or in the air they won’t work. I don’t know how to get them to work. Help please. Thanks in advance.


Are all 4 of your hydraulic pumps on?

Hello, I’ve moved your topic to #third-party-addon-discussion:aircraft for better placement as this seems non-stock. The #sdk-discussion:aircraft section is more for discussing of modifying aircraft within the software development kit (SDK).

Check that your Hydraulic pumps are on, then hit the SYS button to be sure you’ve got full or nearly-full hydraulic quantities showing.

Yes, they are. Thanks for replying.

Yes they are. Where can i find the system button. Still figuring the 737 out haha

Electric pumps are on but still have a low pressure alarm. You’re out of hydraulic fluid. Either that or a popped breaker but I don’t thing the PMDG 737 simulates breakers. But I could be wrong about that because their DC-6 certainly does. Bring up the SYS page on the Lower DU and check your hydraulic fluid. If that is OK, check your breaker panels.

Got it! I didn’t have any hydraulic fluid. The FMS has a ground maintenance interfsce where I could service the hydraulic fluid which I did. It’s working now.
Thanks for the help guys!
