Skulleader Posted December 21, 2014 Share Posted December 21, 2014 Hello guys, During a rampstart I would like to know if it's normal to start successful the left engine without the "Boost Pumps Wing" and "Boost Pumps Main" ? For the right engine I must switch ON the Boost Pumps Wing and Main, is OK. Thanks in advance, Skull :) [sIGPIC]http://forums.eagle.ru/signaturepics/sigpic93192_6.gif[/sIGPIC] My Facebook: https://www.facebook.com/profile.php?id=100006748814655 My P-51D's Mod: http://forums.eagle.ru/showthread.php?t=142739 One of my few skins : https://www.digitalcombatsimulator.com/en/files/1452845/ Link to comment Share on other sites More sharing options...
ptako Posted December 21, 2014 Share Posted December 21, 2014 Yes it is. You can start one engine without boost pumps running.

sobek Posted December 21, 2014 Share Posted December 21, 2014 You can start the left engine without the boost pumps, to be exact. IIRC, the APU and left engine can be supplied by a DC driven pump. Good, fast, cheap. Choose any two. Come let's eat grandpa! Use punctuation, save lives! Link to comment Share on other sites More sharing options...

TIMBER SOUR Posted December 21, 2014 Share Posted December 21, 2014 (edited) You can start the left engine without the boost pumps, to be exact. IIRC, the APU and left engine can be supplied by a DC driven pump. More accurately, while the DC fuel pump is located in the left side of the fuel system, it is able to supply positive pressure to the entire fuel system. However, the fuel crossfeed valve is normally closed, so if you want to start the right engine first using only the DC fuel pump, open the fuel crossfeed valve.

Aginor Posted December 21, 2014 Share Posted December 21, 2014 I think Skulleader just misunderstood you guys. Let me rephrase: No, this is not a bug. This is the behaviour in real life. Snoopy confirmed it. And Snoopy added it is not the normal procedure. So you shouldn't do it like that. :) 1 DCSW weapons cheat sheet speed cheat sheet Link to comment Share on other sites More sharing options...
