Hello everyone, I was on the ground in the MD-11 and I was investigating some test buttons I haven't every pressed before. Upon pushing the HYD PRESS TEST button on the Hydraulic Overhead panel...I got an Amber alert on the EIS saying HYD PRES TST FAIL. The alert I thought was cleared but it stayed on the EIS as HYD rest of flight. Checked the manual and it said I should call maintenance. I seriously doubt someone from MD would come to my house to fix this problem :) LOL...Can anyone help me out here? Also what would be the proper way of testing the HYD system to get a PASS rather than FAIL??Capt Paul

Hi Paul, all 3 HYD systems must be 'off' before you push the test button. That includes the aux HYD pump.Regards Rob

The system pressure must be below 1000 psi to start the test. i.e. no engines or Aux pumps running

Thanks guys...I did get it to work!!!
