Spoken like a high winger. For us low wing types we have to know how
much fuel is in each tank. Since climb, cruise, and descent all use
different amounts of fuel it is hard to know how much is left in each
tank. Sooner or later we come to the point when the POH says switch to
the fullest tank. We need the gauges to know which one that is.
