FUEL SYSTEM INDICATORS FULL

The fuel flow indication is integrated over time to calculate the fuel used for each engine.ħ37-600/-700/-800/-900 with densitometer: During cruise, the tolerance is less than 1.5%. At engine idle, the system tolerance can be 12%. The accuracy of the fuel flow transmitter is a function of the fuel flow. The system tolerance is then +/- 300 KG at any fuel level within the tank. For example, if the fuel tank maximum capacity is 10,000 KG, then the tolerance of the gauging is 0.03 (airplane with analog indicators) * 10000 = 300 KG.

The total tolerance for the FQIS system is based on a full tank. The 737 fuel quantity indication system has the following accuracy tolerances:įQIS accuracy with digital indicators: +/- 2.5 %įQIS accuracy with analog indicators: +/- 3.0%

Power to shut off the fuel in an emergency.ĭigital Sunburst Fuel Gauges - Simmonds 4 Tank NG/MAX: The engine spar valves and APU are normally powered by the hotīattery bus but have a dedicated battery to ensure that there is always They were solenoid held andĪutomatically moved back to OFF after one minute. The 1/200's had heater switches these used bleed air to heat theįuel and de-ice the fuel filter. The -1/200 panel also hasīlue VALVE OPEN lights similar to that on the crossfeed valve. The NG/MAX's have separate ENG VALVE CLOSED & SPAR VALVE CLOSED lights in The fuel panels for the various series have not changed much over The AFM limits are higher, but not normally Upon how many tanks the customer has specified (max 12).

Maximum declarable fuel capacity for tech log, nav log, etc is 16,200kgs forģ-Tank Classics, 20,800kgs for NG/MAX's and up to 37,712kgs for BBJ's depending
