View Full Version : How much does fuel affect performance?

So how much of a difference does it make if I carry less fuel?

Also, how much do you usually carry, and how do you estimate how much is needed according to the distance that must be covered?

There is, in this game, a direct correlation between performance and fuel weight, so the less fuel you take the better your plane will perform due to the less weight. As for how the game predicts fuel consumption of each engine, I have absolutely no idea.

However, each plane is very individual when it comes to fuel, and the travel distances matter very much on your personal anticipation of the conditions of a mission. For example, if I expect to run into combat, I generally tend to take an extra 25% fuel with me. My goal is not to get into a dogfight in the first place, but if I find myself in one and get a few holes in my fuel tank, it enables me to fly that much farther to make it back to friendly lines. The best I can say is: use your common sense.

In typically short-legged aircraft (i.e. bf109, Spitfire and other similar rides), I'll take 75% as a rule. In other rides that have longer legs, like the P-47, P-38 and P-51, 50% is usually more than enough for most DF servers and even coops. If you plan on staying aloft for 40 minutes, you'll cover 99% of most of your flight needs regarding fuel.

I take much the same as TgD Thunderbolt56.

One other thing that has a significant effect is the power settings and the prop RPM. They actually do make a difference. Reduce power and Prop Pitch and you will go further, cooler (especially Oil temp for RPM) and have more of both available for a fight.

I'm currently doing a RAAF Singapore pilot career and I fly the Hawker Hurricane MkIIc now. A lot of missions require me to quickly climb to altitude and then intercept Japanese fighters and bombers.

Given that the Hurricane is a bit of a slow climber, I generally let her run at around 85% power to climb. Works best for me. Then when you encounter the Japanese obviously I'll be using 100-110% power a lot. And that burns gas!

The Hurricane has a pretty short range. Sometimes I am tasked with escorting Blenheims from Singapore to deep into Malaya territory to attack a Japanese base. Theoretically I probably have just enough fuel to fly there, stay a maximum of 3-5 minutes to fight the Japanese and then CRUISE home because I'm already less than half down on gas. http://forums.ubi.com/groupee_common/emoticons/icon_frown.gif


Wait, let me cheat and substitue a P-51D for the Hurricane. http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif

Or drop your settings to 40% throttle/40% prop pitch and hit autopilot. http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

Yes, in the cruise, why not?

but autopilot in a Spit?.... "Hey, fitter....!"

Hi all,

I seem to remember reading on this forum some time ago the following.

If for instance you select 50% fuel, your plane will carry the weight of 50% fuel until empty.

In other words, the weight of fuel selected stays the same until empty.

Pretty sure thats wrong. I've been on a few long duration missions and I've noticed the handling differences as the fuel decreases. The hardest part is hitting refly at the end and then starting up in a fresh plane and saying "why is this so heavy!?" and then you realize.

I could be wrong...just going on feeling.

Fuel affects performance in some planes much more significantly than others. I'll take 25% in a Mustang as it gets to be quite the hot ride at that setting but at 100% its a big of a pig.

You could be right but I don't know the answer http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

But maybe it's impossible for this Sim to calculate all variables with regard to fuel consumption as well as all other flight calculations.

Just my wild thoughts http://forums.ubi.com/groupee_common/emoticons/icon_cool.gif

Differs from plane to plane.
I usually use 75% in German ones, 25% or 50% for US ones, 75% for UK ones. Works good in DF maps.

Sometimes it even pays off to take 25% and fuel tank(s)... as some aircraft doesn't seem to take penalty from tank racks.

It really depends on a mission.

For scramble 25% works in all http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif .

In some planes fuel load is a big issue and you can see plane behaving differently with bigger load.

Well if you tinker with your fuel mixture, you definately can gain some extra range for your cruise to the battle. That I learnt on some 109 campaign missions.

But, does your fuel weight diminish with flight time?

If you start out with 50%, does your fuel eventually reduce to 10% with weight savings?

Answers please!

MB_Avro. Interesting, but I think I'll give a positive answer to this question.

However I cannot claim an absolute truth on this one.

Yes it does

Same with Drop Tanks

A few versions ago it used to be that if you gave AI planes 100% fuel they would quite often crash into the ground trying to maneuver as if they had 25% - in other words the AI did not seem to know to correct for the extra weight.

Not sure it's like that now though as I haven't tried it in 4.09 - maybe something to try tonight...

For Jap aircraft, never take more than 50%,

For Axis aircraft never take less than 75%.

I don't fly the allied stuff.
