La7 flying forever

[Waffle]

La7s seems to fly pretty much indefinate if on climb...

The further up you go, the GPH keeps going down and down, by the time you're at 30k + the ratio of fuel burned per hour to fuel remaining will give you a constant 20 ins flight time.

That MIGHT be because the engine is loosing boost the higher you go (and much like the same boost at lower alts, if you throttle back) you will get more fuel economy. Now, once you level OUT at that alt, what does it do? Does it start counting down from the 20mins?

just put it this way -

I flew an La7 from one HQ to another
