Fighting compression with new settings
« on: April 01, 2006, 08:11:09 AM »
The newest patch includes changes that prevent autotrim from pulling you out from a dive. That's fine -- I'm not the only one  who's exploited that feature when balckouts come too close to the ground....

But now I'm not sure how to recover once the compression threshodl ahs been crossed. In times past, provided you werent too far gone, you could dial trim up and start recovery. That no longer seems to work, and I've yet to make a dent in any compression situation whatsoever.

Also, incidentally, it seems that compressing aircraft now develop a slowly worsening roll from propwash.

So, two historical issues and a practical question.

First, from every account I've read from compression survivors, once lower altitudes were reached control inputs again became possible but difficult. The problems were those of high airspeed vibrations, and just having enough time to get level before running out of altitude. This is not the case in AH, at least from my experience -- it seems that once yo're in compression, getting low makes no difference.

Second, I've never read anywhere about a roll component being experienced. I suspect this component is an unanticipated outcome from the new propwash modelling, but I wonder if it reflects what actually should happen to a compressing aircraft.

And lastly, the question. Do any of you guys have ideas on how to recover an AH compression episode? (yeah, I know, "Don't compress in the first place.")

Best I've ever been able to do is turn the engine off, crank full rudder and hope.

throttle full back, do not turn off the engine (I think it also feathers the prop in P38) and apply some rudder for extra drag. Manually trim full up and pray the wings do not break.

dont fly high enough for compresion to be a problem, simple. :D

see ya "game the game" and now ya paying for it ! :p

I fly the 38 most of the time so I'm a bit aquainted with compression. Bozon said it the way I do it.... throttle down hard rudder, and manual trim up for all your worth !!!! It may take 20-30 stabs at that button, but if ya got the room 1500-2k is plenty you can pull out.

B@t, alt isn't the only factor for compression. The higher you are the less speed you need to reach compression, but you can compress on the deck if ya dive far enough, like chasing down those running La's, spit 16's, pony's and so on and so on.....

Well, thats pretty much how I'd done it until the last patch...maybe I wasnt clear, I havent used the autotrim to dive recover EVER -- so I dont think I've been gaming the game! ;)    

 I have trim wheels on the throttle, rolled up to max when I'm in a plane with reliable autotrim. (I use manual fuill time for Ki84, p38, etc) So, when I need a pull out I can click to manual trim and the trim indicator goes right up to  the top.

Now, though, I'm finding that with MANUAL TRIM and maximal upward adjustment for elevators, throttle full down, that upward slow pitch movement doesnt happen.

Also, there is a roll element that was never present before -- and controlls of course dont respond.....




And -- shouldnt control responsiveness begin to improve at lower alts? In AH, the compression stays more or less absolute at any altitude, which as I said originally doesnt jive with what I understand compression behavior to be. Of course, if you're barely subsonic and 90 degrees off horizontal that wont make a difference, but If you're 40 degrees incline and screaming down to catch that tempest that jsut screwed up....well, you ought to be able to get some pitch up as you get lower, and might even come clase to saving it with "routine" controller inputs...at least from what I've read.

But how will I catch the P38Js with an FM2 if I dont get alt first?  :lol

I have not seen a difference.  It says "auto pilot" is now limited to low G maneuvering.

I cant comment on the the auto pilot thing , but i trimmed my self out of a compressed dive last night just like ive always done with out issue. It seemed the same as usuall .

manually trimming elevators up does the exact same thing pressing 'x' used to do...

Here's a test:
Dive down fast and hit X.
Watch the elevator trim indicator and see if it reaches max deflection.

If it does
  it means that HTC has limited the max possible trim.
else
  it's the auto level that is limited not to use full trim.
end

I'll try it later today unless someone else tries it first.
