TeeJay82 Posted December 4, 2010 Posted December 4, 2010 are they only used as boost pumps while starting the engines? cause when i fly i can turn them off and keep going from full to empty tanks

EtherealN Posted December 4, 2010 Posted December 4, 2010 http://forums.eagle.ru/showpost.php?p=584905&postcount=2 Each engine has an engine-driven pump that "sucks" fuel from the fuel tanks. As long as the engines are working, these pumps are working. There is also a fuel boost pump in each fuel tank, rear and forward. Finally, each external tank has it's own fuel pump (turned on in pairs, you can't have one on and not the other in a pair of tanks). In short: the boost pump is a boost pump. There's no real reason to turn them off in flight, imo, but assuming normal operation of the engines they are not strictly necessary.

TeeJay82 Posted December 5, 2010 Author Posted December 5, 2010 Great ty for the info... dont like to have more lamps lit than nessecary
Haggart Posted December 5, 2010 Posted December 5, 2010 You'll have a lot more lamps lit if you're shmashed in the ground because of motor failure by reason "lack of fuel" in a high-g-manouver. There's no "Overkill". There's only "open fire!" and "time to reload". Specs: i7-980@4,2Ghz, 12GB RAM, 2x GTX480, 1x 8800GTS, X-Fi HD, Cougar, Warthog, dcs-F16-pedals
TeeJay82 Posted December 5, 2010 Author Posted December 5, 2010 Bah... i fly with easy flight model... tried it out going 250+ and then tearing it in 180 turn to a standstill... np
Yskonyn Posted December 5, 2010 Posted December 5, 2010 Boost pumps normally ensure fuel is fed under constant pressure and as redundancy in case there is a problem with the engine driven pump. Boost pumps can also double as scavenger pumps to make sure every drop is going to be used from the tank (737).

Yskonyn Posted December 6, 2010 Posted December 6, 2010 well to be honest I do not know for sure if the boost pumps in the ka50 double as scavenger pumps too. hece the reference to the boeing 737. ;) [sIGPIC][/sIGPIC] Asus Z390-E, 32GB Crucial Ballistix 2400Mhz, Intel i7 9700K 5.0Ghz, Asus GTX1080 8GB, SoundBlaster AE-5, G15, Streamdeck, DSD Flight, TM Warthog, VirPil BRD, MFG Crosswind CAM5, TrackIR 5, KW-908 Jetseat, Win 10 64-bit ”Pilots do not get paid for what they do daily, but they get paid for what they are capable of doing.

AlphaOneSix Posted December 6, 2010 Posted December 6, 2010 No, they don't act as scavenger pumps in the Ka-50...you'll get all available fuel with the boost pumps on or off. The primary purpose of the boot pumps is to ensure proper fuel pressure during engine start. Their secondary purpose is to provide additional pressure to prevent cavitation at high altitudes. I am pretty sure that cavitation is not modeled in the game, so they are really only needed during engine start. Of course, it's a good idea to always leave them on, which is how they are used on the real aircraft.
Yskonyn Posted December 6, 2010 Posted December 6, 2010 thanks for explaining, alpha!
