Happy Happy Joy Joy !
   
What a way to start the New Year !

The only downside is that I won't live long enough to enjoy all of this Great Flight Sim...BAT RULES !!

THANK YOU! To all those wonderful people who keep IL-2/BAT charging into the future.

[Hot_Space]

Thank you for all those involved.

HAPPY NEW YEAR 

[ColdBlue]

Great!!! I'm happy to enjoy new planes. And I also have a little request, could we add MiG-15, MiG-17 and MiG-19 in next update?

As long as you've installed the 4.1 update inbetween 4.0 and 4.2, the MiGs 15, 17, and 19 are already in BAT. You need to switch the era in the selector.

In the selector, click change settings

Switch to "The Jet Age"

Pretty Epic update!

Can you tell me how to upgrade from B.A.T. Pegasus, until 4.2.1

[Vampire_pilot]

welcome back, apparently

You have to start with BAT 4.0, simply installing everything on top of your current BAT install, or on a new one, whatever you prefer...

"How do I get BAT?"

Step 1: Basic install for B.A.T. v4.0

Step 2: B.A.T. v4.1 era expansion

-WAW: several US external tank capacities increased to better match volume indicated.

Nothing has changed for the P-51 D-5. There is not enough fuel in the tanks for the historical range.
The total weight of the aircraft has not changed either, which means that the problem with the tanks continues to exist.

[Vampire_pilot]

Here's what's what.

The P-51 D5 uses the class "FuelTankGun_Tank75gal2"
This version of the 75 gal tank (there are more than one, it happens over the years... decades)  comes at a weight value of 205 kg worth of fuel. This is a correct amount, this is what 75gal gasoline weigh, give/take.

This class indeed was among those reworked. Previously, as stated before, it only contained 156 kg of fuel. So it is increased by ~ 50kg of fuel, per tank.

What is not taken into account is any other inconsistency regarding the engine or your in flight settings. Is your bird a terrible guzzler?
Anyway, the amount of fuel provided is as good as it can be though. Sorry, that's about what I can do.

About historical range in the game.
The game has severe limitations. It gets fuzzy when you really try to build 12 hour round trips or some such. There aren't even maps big enough.  AI can go from Iwo Jima to Japan, fight the baddies, and back on their own terrible patterns on the B-29 alley map in my test mission. To me, that's about as good as the game needs to be really. If you want to enter this any further, you need to go into the java and the engine data and for all birds concerned.

I made measurements under the same conditions before and after the patch. The altitude was 5500, the speed was 350 km per hour. And as in the previous patch, I flew the same distance.
The fact is that thanks to the NG-Hoоd mod, I noted a weight discrepancy. The instructions for the P-51 accurately indicate the weight that should be with tanks and just with a full load of fuel without tanks.
Pay attention when you take 100 percent of fuel without tanks just at the airfield you have one weight, when you take off with tanks another, and when you drop them the third.
Perhaps it is worth setting up the P-51. I do not insist on complete historicity, but it can give it the opportunity to fly at least 800 km with hanging tanks.

Here's an interesting thing. I measured that 1% of the fuel is 7 kg of aircraft weight. At the same time, this equates to ~17 km of the distance you fly with 1% of your fuel. 100 * 17 and you get 1700. This is quite historical. With your modifications, 410 liters is 57 percent of the fuel if 410 kg is divided by 7. 57 times 17. It turns out that you need to fly 969 km. However, plus or minus climb and so on, let's say it will be 890 km.
Build such a route and try to fly it using only external fuel tanks. I will be interested in your observations.

[Vampire_pilot]

You may be very correct. But I look only at the tanks as such and how much fuel it carries.

I  saw what you mean, the increase is only by 330 kg when two tanks are added, when it should be +410
The same can be seen in other planes actually.  Something works here in the background that I don't know about. I have no clue what that may be.

If you have people who understand flight models, could you pass this issue on to them for consideration?
