Aux Fuel

[jcthomas]

Paul!

Looking at the diagrams, there is a difference between a 67 Turbo and 69 Turbo. But, I think the only defference is the type of fuel guages we have. However, when I look at the diagrams, (sheet 2 and 3 of figure 11-1) the legend does not show any fuel returning to the vent lines. If you look at the legend on the NA 337 on the same page, it is clear that the excess fuel can go to the vents.

Please see if you agree with my view on this. I am pleased that you are getting 1.5 from your aux tanks. I would like to be able to do the same.

I still haven't had the chance to try and see if any fuel will come out of the vent lines if I switch to aux tanks after start-up. This is a challenge which I would like to know the answer. It sure would make for safer flying. although, there is nothing wrong with the 1 hour rule and witch to mains for one hour and back to mains. It works all of the time.
