No better, remove Ace of Aces :)

ok?

I would reformulate it like this:
question 12: will the GUI be optimised, to be less clumsy and more ergonomical (today you need several clicks to do simple things), in the same way that RoF optimized their GUI? Today RoF is a great exemple of an appealing, sexy and functional user interface.

Cheers!

10. Will the UBI intro .wmv video issue be finally corrected? Today it clocks down the ATI cards to 2D-power saving mode, and gives really poor performances to the users that do not delete or rename it. That is most of ATI users I guess.

This bug affect only "western" versions of the game

Talking about the intro (with) Ubisoft and 1C, we can not do this deal."

Ah ha.. So is it safe to assume that input was one by you? ;)

Eitherway it will be telling to see Luithers reply to it! ;)

B6: Can we have a static pic of the Ubi-logo instead of the video? That would save us from clocked down ATI-cards and you from programming a workaround.

The workaround couldn't be any easier. I've done it, not because of ATI problems, but just to lower the sim load time.

thats true...but i suspect , that there are many gamers out there, who dont visit this forum, and who are not aware of the workaround and wonder why this sim runs that crappy.

Static stall: 1G flight, your speed decreases, you increase AoA to compensate. Stall happens when critical AoA is reached.

Accelerated stall: same us above, but there must be >1G. In such condition, you need higher AoA than in 1G flight, because lift is countered not only by weight, but by sum of weight and centrifugal force.

Dynamic stall: you increase AoA past a critical value very quickly, vortex is created at leading edge, lift increases, then vortex detaches and you experience rapid loss of lift and sometimes even a high nose-down pitching.

I think, important things about dynamic stall is: amplitude and rate of AoA change, and increase of lift before the stall.

Impressive mission from a sukhoi.ru member posted. Video of air attack and track of a tank attack are included. Works like a strategy game too: you can call reinforcements and schedule your tank attack carefully.

Worth flying and/or watching with external views.

Thanks for the feedback Zaltys..

Looking at your definitions of Accelerated and Dynamic..

Your dynamic def reads just like the link I posted.. Except there is no mention of how the variations in stall are due to the variations atmosphere.. From the link I posted they point out how the stall can vary due to the variation in wind (atmosphere). Other than that the two defs are very interchangeable.

One other thing, you stated you 'need higher AoA than in 1G flight'.. IMHO you should re-word that to read 'during a constant altitude banked turn the AoA will have to be higher than it would be during level flight (1g) at the same speed'.. That example is a little easier for most to visualize. It is also important to note the critical AoA at which the stall occurs is the same for all three cases.
