Guys,several of you have misunderstood what GQ calls `fuel circles`.. more properly they are `fuel check circles`,,,
At the end of each `leg` of the navex ,in planning, a small circle,about 1" diam. is drawn,with a horizontal line across the circle.
In the top half of the circle is drawn the amount of `fuel remaining `expected`.
In the lower half of the circle(probably in `red`,is the `minimum fuel required` to complete the sortie,flying the rest of the route..
Therefore,at all times the fuel in the `top` segment should always be greater than in the lower half....Irrespective of whether you lean or not..
It is a simple `Howgozit`,so that one can check easily if fuel is sufficient.
For those that have drifted into `range circles`,fuel flowmeters and GPS,the OP is just learning his trade with the simple Grob... RTFQ..
