Snappy Posted November 1, 2018 Share Posted November 1, 2018 Hello everyone, is anyone else experiencing a noticable lack of pitch down authority with the new PFM? On my side it is noticable across the entire speed range of the aircraft but seems to get more pronounced at high speeds. The problem is. that even with stick full fwd the nose is very slow to move down, even if starting out from a stable nose level and trimmed out attitude. It takes a lot of additional nose down trim to get it moving halfway decently. On the positive side, this way there's absolutely no danger of red-out in the aircraft right now, but seriously its annoying me a lot, as it takes away some options during last ditch gun defense maneuvering for example. I'm not sure what causes this, even in the cockpit it seems like the control stick is moving a much smaller travel forward at full deflection than aft. Already experimented with tuning axis for pitch, but so far no luck. No problem in other aircraft modules with this. Has anyone else encountered this? Kind regards, Snappy Link to comment Share on other sites More sharing options...

VC Posted November 1, 2018 Share Posted November 1, 2018 This has been pointed out and discussed before, I think it was concluded this is realistic, because Soviet/Russian doctrine was to avoid negative G, and the airframes are not designed for it. If you need to dive, roll inverted, pull, then roll out. VC =X51= Squadron is recruiting!

Snappy Posted November 1, 2018 Author Share Posted November 1, 2018 VC, thanks for your input.I see.Would make sense in a way, if the Soviet design philosophy was to avoid negative G due to airframe issues. Still it seems a bit overdone to me , at least in the high speed regime were it's very hard to get the nose down at all.

AeriaGloria Posted November 4, 2018 Share Posted November 4, 2018 The deflection is limited by trim, full negative deflection is only possible with full negative trim.

Snappy Posted November 5, 2018 Author Share Posted November 5, 2018 The deflection is limited by trim, full negative deflection is only possible with full negative trim. source please? Manual mentions max forward trim range is only 50% of max flight stick travel forward Link to comment Share on other sites More sharing options...
Dudikoff Posted November 6, 2018 Share Posted November 6, 2018 This has been pointed out and discussed before, I think it was concluded this is realistic, because Soviet/Russian doctrine was to avoid negative G, and the airframes are not designed for it. If you need to dive, roll inverted, pull, then roll out. Was it really concluded?

Mars Exulte Posted November 6, 2018 Share Posted November 6, 2018 @dudikoff I've seen references of testing graphs posted round here about structural failure via negative gs on the Flanker. Showed to be very low tolerance. As the MiG is effectively a shrunken Flanker, I would expect it to have very similar characteristics. The Cobra maneuver only works because there is no real force behind it, just the plane lazily drifting around (in the negative range), otherwise it would probably self destruct. That said, it's been a while since that was posted, I think during the Jack McKay/Flanker mega thread, but not sure, and I'm not going to swear by any of it after this much time Де вороги, знайдуться козаки їх перемогти. 5800x3d * 3090 * 64gb * Reverb G2 Link to comment Share on other sites More sharing options...
VZ_342 Posted November 6, 2018 Share Posted November 6, 2018 This thread will probably have the info about pitch down and/or flight modeling used. Link to comment Share on other sites More sharing options...
