Mike Busutil Posted May 13, 2016 Posted May 13, 2016 (edited) Before engine start I check the fuel level in the fuel gauge but it shows zero fuel (even though it's really 100%) until after I start the engine. Is this correct? I thought I recalled checking the fuel level prior to engine start. :book: Edited May 13, 2016 by Mike Busutil [sIGPIC][/sIGPIC] Checkout my user files here: https://www.digitalcombatsimulator.com/en/files/filter/user-is-Mike Busutil/apply/
Frederf Posted May 13, 2016 Posted May 13, 2016 I believe that was a recent change was that the fuel gauge was corrected to not function without the proper bus energized. In any case the MiG's fuel gauge works on the subtraction principle. It relies on being set to the correct value manually and reduces as fuel flow sensors show fuel moving to the engine. This means that it must be manually set whenever fuel is added or subtracted from the total by means other than going through the engine. The gauge should be static when power is removed. The needle being set during refueling represents perhaps the ground crew reaching into the cockpit and twisting the knob on the gauge to match the fuel loaded. I forget if this is allowed/inhibited based on the canopy being open or not. Back to the point, checking the gauge isn't checking the fuel level because there's no physical requirement that they agree. The rearm menu would be a reliable way. Probably the fuel gauge should be initialized to accurate whenever a MiG-21bis spawns though. It's unlikely to park a jet with the needle cranked to 0 when it was full.
