Default Database Loading Issue & Error Message

Any ideas?

Hello Ray,

I am going to defer to Steve's request in the post above. Can you send us an email to I will need to ask a few questions to help get this one sorted out.

This is significantly faster/easier now since you can do this after fill-up from the normal mode fuel calc engine page. Just press Menu on that page and select "Calibrate Fuel Flow" and a pop-up window will show you the fuel used and allow you to enter the actual fuel added to correct the calibration. In this example, the fuel totalizer measured 35 gals since our last fill-up, and we just added 33.5 gals to fill-up.

You can do this as often as you like until the desired accuracy is obtained.

Steve (g3x Expert et al):

Where is the new fuel flow calibration sequence in the pilot's manual or installation manual. I tried to look it up and I couldn't find it mentioned. I think it's really great and wanted to refer a fellow G3X Touch pilot to the official documentation.
