Almost ran one tank dry in a cherokee.
Anyone who ive flown with will back me up in saying im excellent at balancing the tanks to within minutes of each other and was good at compensating for take off at one tank fuller than the other.
Dont know what happened that day, but the math and speeds and flying worked out, just when i got on the ground, there was dregs left in one tank.
Shook me up a bit to be honest.
That leads to the question, people have classic cars, cars far older infact than most aircraft i've flown and yet the fuel guages don't read correctly in the aircraft, yet they do in a car worth far less than the aircraft - WHY
