Le Fokker by Peter de Jong gives diving speed of 673km/h (TAS) for Dutch Fokker. I can reach this without any problems. Even faster is possible but then the engine will overrev and get damaged. Lentäjän Näkökulma 2 by Jukka Raunio has about 6 pages of test pilots descriptions of Fokker behavior. It says that in 90 dec. dive, speed didn't increase over 480-485km/h (IAS no doubt). So what we have in game is faster than this, but the finnish test were done with ski plane so skis might slow down the plane more in dive. Level speeds at sea level & hi-alt are pretty accurate in game too. We spent quite lot of time fine tuning them because fixed prop FMs are tricky to do.

Thats a good point on Wing Bending relief. Its not a factor in the DT revised G module. Wing Bending relief is something very important in long term Fatigue management in large aeroplanes. Most current large transports for instance keep fuel in the outer wing tanks for as long as possible to take advantage of this relief. In military fighter circles its not such a big player. Even in modern flight control systems with active G limiters I don't believe any increase in G is available because a store is on the wing station. The Flight control computers are aware of whats where and that obviously affects some parameters (like rolling G limits AOA etc). In most cases any store means an increase in weight if that weight results in a value over the design (Nzw thingy) then a reduction in g limit applies. In the case of WWII fighters the documentation shows no bending relief credit for wing mounted stores, you put something on the aeroplane (anywhere) the G limit is reduced. As to C of G shift with external stores. Thats already there in native IL2. Try the Yak9B with 128 Ptabs in the back. Its longitudinal stability is pretty average, drop the PTABS and you are back to a normal aeroplane. Why we dont see a lot of this in IL2 is that just about every aeroplane in Il2 has its stores close to the C of G. Flanker35M ... you keep resetting those 811 codes the pilots will keep generating them for you

S!
IvanK, I am now in the higher level maintenance than flight line anymore  But yes, those codes were familiar and all that work that went into checking it all..Sometimes the pilot overstressing the plane was ordered to help us strip the plane etc. so he would appreciate the amount of work it takes to measure and check a plane after Over-G...

Any tips on how to perform wing-snapping maneuvers?
Of course an above corner speed super tight turn, with flaps getting deployed, is one. But any other? Like rocking the plane up and down vertically with the elevators or going from a max inverted G turn to max positive G turn (kind of like a pendulum swing/scandinavian flick in rally racing - it brings more weight than usual come flying which is enough to break traction and stability, and oversteer one gets).

1) While many pilots may need to go through an adjustment period with the new G-limit, I believe that many would also agree that it is step towards the right direction for the sim. It would be interesting to know however which plane would be more affected than others with this limit.
2) Also, I trust that the G-limit be introduced as an realism option selectable in the menu? 3) Lastly I am wondering whether the AI-controlled plane would be subjected to the same limit as the player and whether their behavior would be re-coded to take into account G-limit. Cheers, |

Planes that will be affected? Can try to guess. Anyone feel free to correct any bad guesses/assumptions here
 We already found out that non-fighters (like bombers) are getting the worst penalty, so not going to talk about those. For the fighters & fighter-bombers, without knowing how their G-rating is like. Wo knows, some aircraft might have very high rating and not be affected at all. Good turning ability at low speed: Turning hard means more G generated, but if traveling slowly enough, it does not necessarily amount to a very high amount possible. Result: Minor Penalty Good turning ability at medium speed: The G's start to stack up if turning well. The aircraft that turn well in this range tend to turn REALLY well although the Result: Large Penalty Good turning ability at high speed: Potential to really mess up the aircraft if being a bit reckless on the elevator controls. Good instantaneous turn rate in combination with high speed is maximum Gs possible. Result: Large Penalty Good roll rate: Completely unaffected by the change. Result: Large Improvement (relative to other traits getting worse) Heavier MG's/Cannons options: Strapping on heavier guns and ammo means does not mean more G's, but more strain on the wings at any G-loading. Result: Large Penalty (Bf-110's Bk 3.7 cannon, and Mk 108's come to mind as well as all kinds of gun-pods) Using a fighter platform for bombing (fighter-bombing): The greatest penalty of all, especially if it is a well turning model with high speed abilities. Result: Very Large Penalty High internal fuel capacity: Had some benefit in being able to fly around a lot without suffering the drop tank speed penalty. The drop tanks can at least be dumped at any time to lighten up the plane. Result: Minor penalty Forgetting to jettison bombs and drop tanks before maneuvering wildly: Result: WINGS OFF! The traits are so dependant on the type of fighter, and who knows of how durable each model is. Are energy fighters going to be affected at all as long as they stick to 'energy fighting'? Are turn fighters going to be affected much, as they can already turn beyond blackout point and still probably be below the service loading? Will the FW-190 be affected much, as it's roll rate is more valuable but the quick short jink style turns are less available? Will the twin fighters get affected by their heavier armament/bombs and poor roll rate, as they usually go into battle with very low fuel (compared to what they are capable of carrying) and them probably being built to be very sturdy anyway? Will diving fast make much of a difference, as the elevators suffer compressability at high speed anyway? I think the Fw 190 will be affected when on the defensive. And that single-engined fighters will be worse for bombing and fighter-bombing. I cannot tell about twin engined heavy fighters when carrying bombs out there... the lighter bombers (AC-20) is already known to be affected strongly, and how much different is the 110 really? If rockets are much lighter than bombs, then the P-38's should become an even more preferred method to kill things on the ground with. Having a very heavy bomb-load will be worse, in any aircraft. Maybe there's more incentive to choose a bit less extreme bomb load. Drop tanks to carry fuel in should be more valuable than putting it internally (done to avoid the speed penalty of drop tanks otherwise). The tank can be jettisoned any time anyway and the manuverability is unaffected then. |

What stress model with multirole aircraft like the Mosquito and Beaufighter get? Fighter or Bomber?
And will dive bombers like SBD's and Stukas be stressed apropriately? Last edited by Skoshi Tiger; 03-06-2010 at 01:44 AM. |
