Herman's suggestion is an "acceptable" interim/stand-in alternative .... in the absence of anything else that's representative of the B717-200 specifically and for FSX use. Sometimes that all one can do The actual B717-200 panel resembles something more like like this though .... .... featuring large EFIS/glass type displays as can be seen above. I think "some" (not all) of the very late MD-80/-90 SERIES aircraft may use something like this or have been upgraded to a similar standard (?). The above panel was authored by Steve SOUTHEY. This one is for FS2004 use .... and is the one currently offere by HJG. There may be an FSX compatible version of it by now .... but .... I don't know .... one would have to check AVSIM.COM , FLIGHTSIM.COM, and SIMVIATION.COM libraries. "IF" .... there is an FSX compatible version of it, then, just how well it might, or might not, run with the HJG B717-200 simulation is anybodys guess (?). Mark C AKL/NZ

That one does certainly seem close to a real 717 cockpit, with the exception of the brown background.
I will consider the CRJ cockpit to be an acceptable stand-in as long as it works without issue.
I may also try my MD-80 cockpit or venture over to AVSIM and see what I can find for a 717.

Did a search for an FSX 717 cockpit\panel. Found this one at flightsim.com. Compare this to the default CRJ 700 panel. Herman

It's been a while, but I'm back.
I haven't solved the problem yet. Interestingly enough, I did a short flight from KSAN-KLAX cruising at 10,000 feet and achieved smooth flying. I guess it only happens above a certain altitude, which I haven't discovered yet.
Also, what's the chance this is not a panel problem? Even changing the Autopilot section of the aircraft.cfg does nothing to the panel, but just modifies how the autopilot works. Is there a chance I could just change something in the aircraft.cfg? Could it be something in the .air file?

Instability issues during high altitude/high speed AP controlled cruise can happen with "some" simulations (that's known/documented) .... and in cases where simulations are affected by these issues then such problems are also known to (usually) be panel/gauge related and normally only commence, and progress, from around 25,000 FT. There was once a time .... 9 years ago .... where, during high altitude/high speed AP controlled cruise (above 25,000 FT) that our own B707/720 simulations, using our own then current version B707 panels/gauges (2006 .... long since replaced/upgraded) demonstrated a very similar tendency .... until we traced the problem back to the AP gauge programming and eventually solved this particular issue (during 2007) .... and it's never happened since. Just going back over your previous postings on this thread .... I thought this issue had been resolved as previously recommended and tren reply posted by you .... Not so ? If my earlier suggested AP related CFG data swap hasn't resolved your particular issue .... then .... I don't know what will I note you appear to be continuing to use a non-HJG .... possibly CRJ or EMB jet type panel .... SO .... I once again "suggest" the issue, you say, you continue to experience, is likely the result of AP gauge incompatibility between this panel selection and our simulation. If you desire to continue using that particular panel of choice .... then .... I don't see/know of any resolution to this particular issue. In the case of some (though not all) simulations one can't use "just any old panel" .... as such issues may be bound to arise .... BUT .... it does surprise me that you did previously state that this issue is apparently ocurring with a default FSX panel version .... and which shouldn't normally be the case. I've flown our B7i7-200's .... "in FS2004" (and I understasnd Herman does so too in FSX) .... using our own recommended/hosted B717-200 panel (which incidentally "is not" FSX compatible, BUT, nor was it designed around the HJG B717-200 simulations or any of our B717-200/MD-80/-90 simulations designed around it either, since our hosting this particular panel version was "as coincidental as it was convenient") and I .... personally .... have only noted our simulations (both B717-200 and MD-80/-90) to behave perfectly (very stable) using it and at all altitudes .... up to around 31,000 FT .... and which is "a good intermediate altitude" for most medium range flights. As I recall .... my own experiences/sentiments have been echoed by other users earlier within this thread. We don't have .... or know of .... any FSX compatible B717-200 suitable/compatible panel (at least not one we care to recommend) .... SO .... I regret to say we can't offer much assistance .... it seems In this particular case .... you may need to search for "another" FSX compatible panel (and gauge set) option .... and just hope for the best. I can't recommend an AIR.FILE edit either .... at least not one that might not run the risk of buggering up something else .... and certainly not for a panel we neither host/offer or underestand be it default or otherwise I can therefore only conclude by saying .... "On the basis of our own experience" .... and even in the absence of an FSX suitable panel .... the HJG B717-200 simulation "are" FSX portable (but not FSX native) and "are" known to perform OK within the FSX environment .... despite the fact they're actually intended for FS2004 use.

Could it be something in the .air file?"As you don't experience the problem at 10,000 ft, but do at higher altitudes, then this is most likely a Mach effect, not altitude. At 10,000 ft you are probably at best around M0.4-M0.5, but at FL350 the plane should be around M0.8. As Mark has tried to state, in FS there's a complicated relation between the FDE and the panel gauges. Changing the cfg parameters can be a first step in isolating/solving a problem, but it must be understood that all the cfg does is over ride the parameters in the air file. The cfg is a convenience introduced to edit the most important parameters found in the air file. So, I would suspect the trim offset needs to be adjusted in the air file. HOWEVER if you adjust this, fully expect other flight issues to immediately show up. As Mark says, tuning an FDE is a delicate dance revolving around the model, the weight and balance parameters, and the XML programming inside the panel gauges. That is why Mark is recommending the panels that HJG has tested the planes with to be used with those planes. Sometimes you can get away with a substitute such as Herman suggested with an MD80/90 panel as the 717 is essentially the same aircraft. BUT, the CRJ is nowhere near a 717 in terms of weight, wing span, etc etc, so that panel most likely is not compatible withe the HJG air file. Ask Mark and George about how we spent 6 (?) months or so testing when George upgraded the L1011 AP xml programming, and the fine tuning it took between the XML programming and the air file to get that wonderful autoland feature now available in our L1011. Importing that L1011 panel into a DC10 would be disastrous. I know, long-winded....sorry Mike
