Hi everyoneCan someone please educate me?, since I installed the NGX SP1 update, my hydraulics elec 1 and elec 2 pumps have been getting overheated, it only happen when I start from cold and dark, doesn't matter what I do or how I set up the aircraft my hydraulics elec 1 and elec 2 pumps will always overheat, can someone tell me why it happens and how to get rid of it?, I have service-based failures active on my ngxthis one is with the hydrauclic pumps offthis one is with the hydraulics pumps onNygel Norman

What does your fuel temperature gauge say? If it's off the charts, then you've used an old/obsolete panel state, and the fix would be to use a new SP1-friendly panel state. For more information view the main sticky at the top of the NGX forum. [ http://forum.avsim.net/topic/352155-post-sp1-do-not-use-old-panel-states-and-option-inis/ ]

My suggestion would be to start with a different panel setting, turn everything off, then save that as your "cold & dark". More than likely your fuel temperature is off the scale, and as far as I know there really is no other way to fix it than the way I described.

I'll try that, thanks you so muchNygel Norman

Make sure there is a minimum of 1675 Lbs/760 kg of fuel in the main tanks to cool the heat exchangers, If not, Do not operate the "Hydraulic" Electrical Motor Driven Pumps (EMDP) for more than 2 minutes to prevent a overheat of the hydraulic case drain fluid from the EMDP's of hydraulic system A and B.
