Airbus A320 Family Development

[IAHM-COL]

Ok. You are correct. I just got the same.
I'll address this.

IH-COL

[IAHM-COL]

Ok
I just double checked
http://www.flightgear.org/legacy-Downlo ... v2.12.html

There is certainly nothing at w050n40

Correct tile is

Code: Select all

install/tile w080n40


For NY state

By the 11th, at least the A321 should be complete.

Thanks for testing guys

[IAHM-COL]

Ok. shoot me a note. If it is complete on the 11th, I'll repeat the craft.

I just flew a fully overloaded (whatever I could get in it including overweight pilots and flight-attendants) A320-200 out for a spin. Manually, even with keyboard alone, she does fine, but something out of the systems gives her always a slight roll to the right (and right-aileron is perpetually set to-6 degrees after the AP was active).
So, manually, it works fine, with AP, auto-throttle fails (she went at some point up to 460 KIAS), pitch goes totally out of whack, she tried to blinb with 25 degrees nose up, and the roll to the right is compensated by aileron trim to the left ... which makes no sense because the roll came from a wrong set right aileron to begin with.
So, this appears to be more of a system problem than actually an FDM problem. If the AP pulls the still full and then pushes it again full and then pulls it again, she will swing, no question. The other thing is, you can of course load every plane to hell. Just fill only the forward passenger compartment and the forward cargo hold, leave the rest empty and she is so nose-heavy, she won't recover. However, if you do that with any other big plane in rl, and you get the same problem. So which way to go? Want faked compartment positions to make sure, even if the load is totally unreasonable, she won't lose balance? I honestly don't know where this goes at the moment.

Addendum, I tried full forward compartment loaded, nothing in the rear, she is so nose-heavy you won't even get her off the gorund. Then the same backward, means aft compartment full, aft cargo full, nothing else. She sits on her butt, that's it. So yes, stupid loads can cause stupid results abd after we have proven this obvious point, I bow out for now and take care of my other work, that's a systems problem.

Confused...

For me, the CG is so specific, I can't move it at all!

[jwocky]

No, the problem is, your AP reacts too hectic
when the plane climbs, you go in too steep climb and if you trimmed it only a bit nose-light, you get into some weird loop when you try to get the nose down again. You need a faster controller with with less change. Short integration time, little steps.

[Octal450]

Yeah I know.

But it works fine until the CG changes... most of the time

I'm adding more values to be changable from the -set file (keep drop-in upgrades)

Then it will be tunable properly.

Yasim planes need a slower controller, JSB needs a faster one in most case I find. Remember that the ITAF came from the MD-88 AUTOFLIGHT system (IT1) which was for a YASIM aircraft.
