Fuel economy/efficiency

[qts]

Where can I find details of fuel economy and efficiency in AH? Sometimes I'm helping cap a field, check my fuel and have to decide whether to head for home or stay and hope the field gets captured before I run out of fuel. Also I guess altitude pays a significant part.

A few planes have cruise throttle settings on the AH website.

There are also charts somewhere for the clipboard map that show fuel endurance of the various planes at full throttle(Anyone have the url?)

When you find yourself wondering if you have enough fuel to go home, generally decreasing your RPMs a few notches, and throttle to about 60% your range will get much longer.

heres a cool chart made by another pilot in AH for all to use:

the way to use it is check against table how long it flies then look at your tank, if its at a 1/4 on the gauge divide the total flight time by 4 and you got how much time you have left.

using wep increases your burn rate so you have to just get used to that through experience.

Like you can see on the date, that chart is well over a year old. I made an updated one when 1.10 came out. It can be found here http://home14.inet.tele.dk/snefens/fuel.zip

I originally did it, to be able to figure out how much fuel I had worth in planes with multiple tanks (having 2 wing, an aux and main tank with different sizes it, makes it hard to judge in flight).
So by the start of each sortie I always multiply my fuel load with the endurance, and then find out at what clock I approx will run out of gas.

For instance. Time is 10:15. I take a 110G up with 75% fuel in MA, which will last approx 0.75*38min = 28½ min. I should therefore be looking to be back at base before 10:44, give or take a min. Easier than to have a stopwatch going by your side

The time can obviously be extended by cutting throttle.

BTW, this is great to couple with the ETA chart that was presented here some months ago, but I can't remember who made it? One of the Finns (non-LLv34) I believe.

I can attach it here later if we don't find out who made it.

Cruise settings? Hell that's easy. Just drop 15-20" off the MAN and dump around 1,200 RPM. You'll go clear across the map! Granted a Feisler Storch could outrun you at those settings, but you'll do it.

Here's a little info from a page I've been workin on for the ol website....

F4U-1D:
38"@1800 RPM = 50% increase in range

F6F:
40"@1500 RPM = 50% increase in range.
Max flight time: 180 minutes (1x fuel burn)

P-47D:
35"@1500 RPM = 60% increase in range
Max flight time: 360 minutes (1x fuel burn)
