rami80 Posted December 27, 2015 Posted December 27, 2015 When pulling the stick back with the FBW on, the plane only reaches 9gs for a second and then hovers around the 8.5g mark. Is the Su-27 limited to 8.5g?
TheFurNinja Posted December 27, 2015 Posted December 27, 2015 The operational limit for G forces is around 9G's. It is to preserve the airplane's structure. In-Game Handle: Lutrafisk She/Her
ineth Posted December 27, 2015 Posted December 27, 2015 well it is not totaly wrong i guess. I remember from Falcon 4.0 manual the F16 reached 9g between 340 to 460 knots iirc. Since puling hard bleeds speed sooner or later you ended up near 6g at best. The Flanker with its 2 engines should be able to better that by a bit. Not certain about the exact numbers nor about the actual performance envelope of the Su27. Fly safe. Greek/German origin. Flying sims since 1984. Using computers since 1977.

Brisse Posted December 28, 2015 Posted December 28, 2015 Usually the 9g fighters will be limited to 8,5g +-0,5g so a possible maximum of 9g, but not necessarily exactly 9g.
esb77 Posted December 28, 2015 Posted December 28, 2015 (edited) The Su-27 can pull 9 gs or possibly a bit more (which is more than most pilots can really handle). There is a "soft limit" in the FBW system, that on the real plane you can override by just pulling back really hard on the stick. I believe that this is modeled in DCS only instead of pulling harder on the stick you press the wheelbrake key. There's a thread about this floating around on the forum somewhere. This is a separate function from disengaging the ACS in order to do airshow stunts like the Cobra. edit: As a lot of others are pointing out though, there's a difference between instantaneous max turn and sustained max turn.

I combine the two by predictably boring large holes in the ground with my plane.

PiedDroit Posted December 28, 2015 Posted December 28, 2015 There a "soft limit" in the FBW system, that on the real plane you can override by just pulling back really hard on the stick.

This is a separate function from disengaging the ACS in order to do airshow stunts like the Cobra. The key to press is LAlt+'a' by default IIRC (AP disengage / enable stick hard stop), map it to pinky button on the stick. Limits are theorically 5.5g / 8.5g on elastic stop and 6g / 9g on hard stop (stores / A-A configuration).
esb77 Posted December 28, 2015 Posted December 28, 2015 (edited) According to this thread it's W for the pullthrough of the soft limit. http://forums.eagle.ru/showthread.php?t=154301 Of course, it's quite possible that there are multiple keybinds available for this, or that things have been changed in a recent patch. Lol, it's a thread by rami about the override function. So they already knew about it. Yeah, in that case it's just a matter of max instantaneous turn rate being, well, for an instant. That and being at the flight parameters for peak performance as shown in the relevant performance charts. Edited December 28, 2015 by esb77 Callsign "Auger".
