Game Hurricane is 534 lbs overweight

97 gallons is the fuel tank capacity, of which 94 gallons are useable. Usually the 3 unusable gallons are included in the tare weight.

The TARE weight of the Hurricane IA Rotol with bullet proof windshield and armour plate used in the RAF test was 4982 lbs/2265 kgs, which is 744 lbs less than the TARE weight of the game aircraft which is listed as 2603 kgs/ 5726 lbs.

4982lbs is the weight of the aircraft without bullet proof windshield and armor. These items were not actually fitted, but the plane was ballasted instead and the extra weight is included in the service load.

Very interesting. One point which might be worth considering is whether the real life weight includes a pilot. If not then the game weight would need to be a little heavier to allow for this although you would be unlikely to have a 700lb guy sat in the seat!

Just for reference - 1 gallon of British fuel weighed 7.2lb (Spitfire - The History)

Whew, gotta cut down on the beer and sausage!

Good find guys. The devil certainly is in the details. 1C have indicated in the past that they model on real specs. Hopefully they will get to them before the final patch.

Cheers

Pilot is part of service load and included. It should still be noted that wartime tare figures and in game tare figure have little in common, what one has to look for is that fully loaded planes in game and real life have the same weight, and that usables like fuel and ammo correspond to historical figures. Empty weight historically, depending on air force and time, sometimes does not include guns, radio, armour and other things like survival gear, flares, gunsights, guncams, oxygen equipment etc., while in game it does.

but that logic should then similarly apply to the spitfire and 109, yet neither of those has the "overweight problem" that the hurricane indicates according to Buzzsaw's OP

All 109s were too heavy when I last checked. Haven't noticed that this has been corrected, yet, either.

[Kwiatek]

FM and performace still need a lot of correction in CLOD:

- wrong weight of planes - overweight

- wrong maximum speed - all fighters are too slow

- wrong climb rate - too slow climb rate at medium to high alts

- wrong maximum service celling - way to low service celling

I know ( beacuse i was FM modder in old Il2) that such things was possible to make in il2 1946 i wonder what stops 1C to make it correct and more acccurate in CLOD???

but by only about less then a 1/10th the amount we are now discussing for the hurricane, so not really relevant

if buzzsaw is correct, and by all indications so far he is, then this is a massive problem for the hurricane which needs to be resolved quickly

It doesn't matter so much because how the FM is set up. The basic performance data seems to be set in stone (speed, climb, turn), and the engine just works out the results for different speeds/angles of attack/altitudes. More weight just not effects the raw performance so much as in real life, though it may well effect the handling/behaviour.

For example, since power and max speed are set, the engine may work out the acceleration from this, for which it also takes account weight. In the end, acceleration for example may be less due to increased weight, even though the plane reaches the same speed and turns just as well. OTOH it may well dive better than it should due to increased cross sectional densitity.

In short the effects are secondary, not primary.
