dagebow Posted December 16, 2018 Share Posted December 16, 2018 I am wondering if anyone can advise when the manual override button located on the Rudder Boost Diverter Valve would be used? We have imagery but no actual technical notes advising of what the intent of the button is other than a manual override. We are guessing it is in case the hydraulic pressure does not change when the flaps are raised/lowered beyond 15% but we are not 100% certain. This is on a C-130J but was also used on the H and E models. Thanking for any assistance in advance. Quote Link to comment Share on other sites More sharing options...
hehe Posted December 17, 2018 Share Posted December 17, 2018 Pretty much just used to help troubleshoot. Crew would never lay in the door and hold that button until they land unless there was something serious going on. Pressing the manual override forces valve to act as if it was energized. Pressing manual override valve is same as flaps extended past 15% (+/-5%). High boost state is energized, low boost state is de-energized. Pressing button is high boost states Quote Link to comment Share on other sites More sharing options...

hehe Posted February 27, 2019 Share Posted February 27, 2019 It is also on the aileron control panel if you are working on short J's. Stretch J's (-30) do not have aileron diverter valves. Quote Link to comment Share on other sites More sharing options...
