Again we used the opportunity of the crane to check the amount of unusable fuel in each tank. The Rebel was put into the worst fuel conditions, which means nose down.
Following values of unusable fuel were measured for each tank:
X-achsis shows angle of attack (-9° = ground position), Y-achsis shows unusable fuel quantity in liters.
Since normal maximum downward degree is 4,5 degrees, an unusable fuel quantity of 9 liters per tank is appropriate. Of course there is an additional extensive protocol available for these tests.
