I can't see any stated G-load limitations in the Mosquito document anyway, so this doesn't really help.

AndyJWest you was misunderstand me. I wasn't compared P-51 and DH Mosquito. You was right, it isn't similar. I was only illustrated a metal and a wood constructions limitations. G limit is a "IL-2 Sturmovik" game feature, who simplify simulated a forces has affected flying aircraft. The game wood construction strengthen can be stronger like metal. Flaying limitations in P-51 and Mosquito pilot manuals is a G limit. Sorry, but I hasn't real aircrafts G limit comparison tables. We can compared only flaying limitations in pilots manuals or calculate and compared aircraft strength in different flying modes, but this is a hard work.:) So, let's look in pilot manual, Mosquito hasn't a diving limitation. P-51 has and can diving beyond 75% of the speed of sound.
Question: Is it meaning, Mosquito is stronger like P-51? Why DH Mosquito hasn't diving limitation, but P-51 has? Is it meaning, fully loaded real DH Mosquito can diving without limits?
The game Mosquito can. Is it right?

That weakens the construction quite a bit! A metal construction doesn't forget stresses!

Huh. You know some builders in my town thinking like you. You know what happened with them? They are in jail now. They took off ceiling general support pylons and wood covering little bit overstressed and broken down. 3 peoples was killed. Is ceiling has a metal rails covering 3 peoples doesn't die. Its only sagging, but not breaking. That is wood and metal constructions difference. Wood is wood, metal is metal. Thats not important where are you used it.

In the context where i posted this its meant a SLIGHT overstress, say 5 to 10 %, for a short period of time, say 5 to 10 seconds,
as one might expect in a break turn or a pull-out.
That is a unintentional overstressing.
I believe what you wanted to say is that someone was building a roof not acoording to the expected loads,
well, thats intentional and really doesn't reflect the situation that i pictured.
Anyway, that a metal construction only sags if overstressed to the same degree as a wooden construction is very hypothetical and hard to prove.

Stress and strength
 
To stop this pointless discussion about wood vs metal:

For any mechanical engineer it is absolutely obvious, that if an object is properly designed to withstand a certain load, it will withstand it, no matter which material it was designed and built from - wood, steel, aluminum or even $hit. Offcourse, each material has it's limits and for certain tasks some of them aren't applicable at all. Like, you can build a plane from wood or metal, but you can not build it from a $hit, though you can build, say, a house from any of the listed materials.

So, the final point is, if, for instance, we have two wing spars, one of them was designed and built from wood and the other one - from a metal and both are supposed to withstand 8G, they both will do it absolutely equally. Period, nothing to talk about any longer.

About fatigue. Again, no reason to even take it into account, because material fatigue is a rather continuous process, it is generally impossible to reach a dangerous level of it during one mission, unless the airframe does not experience flatter (damage from which is modeled in the game). And, as we all know, the every next mission we fly in a factory-new airplane, which does not have any fatigue or other damage accumulated yet - that's the game limitation. It does not have any mean to transfer your plane state from mission to mission. Hence, no reason to model fatigue. And discuss it in relation to the IL-2 either.

That's all, folks.

Well said. I would have posted something like that myself but I just didn't bother. People posting incorrect stuff about that lack technical education IMO.

Maybe SoW will have such a feature, to simulate fatigue over continuous period of missions...

I have a question regarding the G limit, too. Nothing technical in nature though, rather something to ease tensions with this new feature.

Will there be a HUD message that will display current Gs? I think this would help people a great deal to adjust their flying accordingly. If I'm not mistaken something like that could be seen in the video that came with the dev. update for the G limitations.

Good point and good idea!!
HUD G meter will be needed

ElAurens 05-03-2010 04:38 PM

You already have two G meters on either side of the cockpit.

Just ask any P51 pilot.

AndyJWest 05-03-2010 06:11 PM

Offline, you can get 'G' via DeviceLink with external software (the documentation calls it 'overload', but it definitely correlates with G).

Other than that, you'll have to rely on experience, like real pilots of the time did - though they probably only got it wrong once...

Agreed with you but it's just to familiarize with this new feature and to understand the new aircraft's limits
