Rainbowgirl Posted April 2, 2023 Share Posted April 2, 2023 (edited) Hello! For some reason Spitfire as only warbird in DCS has tendency to cut off engine as 5000 metres altitude is approached. The plane is set to Auto rich mixture, Ram air enabled, RPM and PSI in norm, supercharger in AUTO. According to manual the plane is equipped with automatic fuel pressurization at around 20 000 feet, so boiling fuel should not be the reason, too. Has anyone idea what is the issue? Thank you.

Solution Ala13_ManOWar Posted April 2, 2023 Solution Share Posted April 2, 2023 (edited) No, the fuel pressurization isn't "automatic", you have to switch it on (perhaps open the knob, better said) whenever you climb to that kind of altitude. As with the supercharger, since it's atmospheric pressure dependant, it's not always the same altitude you should have to use it as it's not always the same altitude when auto supercharger kicks in second stage. You could check the electric fuel pump either, since its not mandatory when the wobble pump is used to start the engine, but again at altitude you might need to use it or pump manually all of the time.

razo+r Posted April 2, 2023 Share Posted April 2, 2023 Turn on the electric fuel pump, which is a switch located below the elevator trim. 1 Link to comment Share on other sites More sharing options...
