3/1/2024 0 Comments DELUXE AIRCRAFT FUEL CHECKER![]() ![]() ![]() ![]() fuel fed from the right wing won’t have the pressure on the left wing it does due to the extra run length to get it there. Once you know how much fuel pressure is available, you need to know how much fuel pressure is changed via the tubing that takes the fuel from the tank to the port. To fix the fuel issue is a big thing to overhaul the fuel system.įirst, you need to know the fuel pressure given the configuration of the aircraft and fuel in the tank at the drain port…less fuel makes less pressure on the feed drain port, so as you run lower on fuel, the pressure will exponentially lessen (not linearly). it does affect fuel flow in these extreme conditions as without the fuel pump, the fuel flow (and thus mixture ratio) will be lessened due to lack of sufficient pressure of fuel and not enough fuel will reach the engine for the mixture selected. It’s not just that tho…it’s about how the entire baron fuel system works that needs to be addressed…įuel pumps off, you have 0 control…either fuel flows or it doesn’t, but there is no calculation that says x% mixture is needed minimally for combustion while Y% is the maximum needed at which the cylinder is flooded with excess gas and cools the egt and reduces rpm slightly…then if you add fuel pump, all it does is ensure there is adequate pressure on the fuel lines given the baron is a low-wing aircraft, that during less than 1g maneuvers fuel will still be forced to the high-mounted engines. ![]()
