FoxTwo Posted September 5, 2020 Posted September 5, 2020 Found some information that described that the F-16 fuel flow rates above 18,000pph (for centerline) or 30,000pph (for wing tanks) will start to consume fuel from the fuselage tanks because the transfer rate is not sufficient to feed the engine. This should drain the fuselage fuel and prevent the siphon action from the external stores, at which point the wing turbine pumps are pulling a maximum of 6000pph from the stores into the fuselage. At THAT point, extended operation consuming more than 6000pph could cause an engine flameout. Basically you can get into a situation where it looks like you have plenty of fuel left but have a flameout because the engine is starved due to inadequate transfer flow rate. However, in DCS and just going all out at full AB with external tanks, what seems to happen is the center line tank is drained, then the wing tanks, then the fuselage. It doesn't seem like the external store fuel flow rate is being considered or the fuel transfer is modeled at all, unless I'm missing something obvious.
