Has a change in the Mosquito's fuel loadout/usage been officially annouced by HTC? There were a bit of rumble some months ago about this one especially. Both others (Karnak) (http://www.hitechcreations.com/forums/showthread.php?s=&threadid=68371) and I found the endurance at the time to be 34 min at x2 burn.
Now when I'm testing again I get it to be 43 min. Have they changed it without telling, or did I just miss it?
I also found that the jets, as the only two in the planeset, use less fuel when they go higher. Shouldn't all planes (maybe with exception of Me163) get higher endurance with alts.
I can't say I've tested them all, but the 8 or so I did test had exactly the same endurance at 20K as at SL.
Anyway, I added the new values to my endurance charts.

All aircraft get higher endurance at higher altitudes. Thinner air means thinner mixture. Thinner mixture means less fuel being used...

OK, the question then is if this is a bug or a 'feature'.

Depends on your position; if you're a:
user, its a bug
designer, its a feature
Hehe.

This is not true. Thinner air means a RICHER mixture which is why pilots had to manage the mixture. If the plane had an automatic mixture control it would work up to the critical altitude when the air got too thin to compress in the turbo or supercharger to maintain full power. The pilot still had to select auto rich or auto lean to set the AMC (automatic mixture control) for operations. Heavy manipulation of the throttle (ie max power or wep) set the mixture even richer to maintain coolling in the engine. Water injection was used to cool the engine and prevent detonation at high boost.
You are right in that thinner air means less friction or air drag so that planes used less power to get the same speed up to the critical altitude when cruising. Propellor efficiency also drops off as the air gets thiner as well. This can also be a limiting factor in a planes speed.

Jets are more efficient at higher alts and speeds than prop planes. The Ryan Fireball is an example of the Navy trying to create a hybrid that had the strength inherent in both the prop and jet.
