Yet another specimen from my generic panel, this time a fuel gauge designed for twin jet engines. I think it would offer the experimenter a good chance to modify the XML to match their particular requirements, here is the specification that I needed and made this gauge to suit. Total fuel qty. - 800 gallons. Max. flow rate both engines combined, reheat on - 3500 gallons per hour. Display of remaining time based upon current flow rate. Display of all up weight and fuel weight. Show too heavy for landing condition, by means of colour changes to AUW and FLW. Gradient-style bargraphs for fuel qty. and flow rate. Clickable selection of left, right or both tanks. All the control parameters are easily modifiable within the XML, I have included comments explaining the functionality. If you have any questions you can email me. George GeoDen@blueyonder.co.uk
