Kayos Posted May 31, 2017 Share Posted May 31, 2017 Can you only use the Drop Tanks in the Air? I tried switching to Drop Tanks at the runway just before take off and the engine shuts off. After start up if I switch to Drop Tanks the engine will shut off too. [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...
NeilWillis Posted May 31, 2017 Share Posted May 31, 2017 For take off and presumably, when on the ground, the main LH tank because this is the one that vents fuel to the atmosphere in the event of over filling the tanks. Only when this tank has fallen to a manageable level should fuel be drawn from other tanks. Why the engine shuts down if you select the external tanks I am not sure, but it is possibly due to a loss of fuel pressure perhaps? There are no booster pumps in the wing tanks, so they rely only on a pressure bleed off from the vacuum pump. That may be insufficient under low altitude/high fuel demand situations? Whatever the details, the LH Wing tank is the only one suitable for take off. Link to comment Share on other sites More sharing options...

Basher Posted May 31, 2017 Share Posted May 31, 2017 I thought that I read it somewhere in the manual that if you switch to any other tanks on the P51, you need to have the boost pumps on. This would include switching to the wings tanks as well. I thinks its modeled that the engine would get starved as the pressure between tank switches is not enough to feed the engine.
