So I need a little help understanding the fuel system. I do know how much fuel to put on every flight but I just want to know what these numbers on the bottom mean. Does this mean the amount of fuel left (in hours)? And when I am doing my VFR flight, I like to test how far a route is and I see sometimes the “ETA to dest” is red. I will post a quick image below. I had to put the UI real quick to demonstrate it.
Also this summer, I have finished up my high school classes which means I have the time to do long haul flights for the first time and I need a little help from the community. Any tips would be helpful.
