I took a look at three different loading envelope versions over the years of the SR20. The envelope at the high-weight end hasn't really changed, but the low end did get extended, so the aft limit looks kind of like the DA40, being 148 in. at all weights. now, where once it was less at lower wights....

Notably the replacement of the KCS 55A with a G5 suite might move the empty CG back by about .1 inch. It depends on the single factor of whether the KG 102A is beneath the rear passenger seat, as stated in the AMM or is located in the front instrument panel as implied by the POH. It is definitely u...

Just saw this on the FAA accident/incident site for a DA20:

AIRCRAFT LANDED RUNWAY 30R WITH NOSE WHEEL MISSING.

Jeppesen has now fixed the problem with JDM and Skybound on Mac. Tested yesterday.

Tim, I think they started out with wider envelopes. The plane gets heavier, you up the max weight, maybe stiffening a part or two. In addition to the narrow envelope, Diamond's mistake is twofold: The bunch of added weight in the rear of the plane , and the additionally restricted envelope when prov...

FWIW, I paid $225K for my plane. Since then I've added/replaced stuff to the tune of about $30K. More than half of this amount was spent in acquiring equipment that essentially cost the same as that which it replaced and the installation thereof. If I were ordering a new one today, it'd basically be...

I have actually been seeking W&B info for the Panthera and have been unsuccessful. There's no way to know about its loading capabilities until one has that in hand. Even then, in the absence of actual, delivered, empty weights/CGs the proverbial grain of salt must be taken. I'm being misquoted here....

Basically you are stating the CG range is too small, or the load pattern is not close enough to the center of thrust making it have a disproportionate effect on CG. Tim For purposes of this thread, I'm pointing out that the nominal CG range adequacy is reduced if the plane is made lighter. For me, ...

I also worry about dropping the screw

Here's an interesting wrinkle to consider. The lighter an airframe is the more impact on CG a given load will have. So I did a what-if analysis. Specifically, what if my plane had an empty weight of 1500 lb, rather than its current 1705, with the same forward CG it has now. Here's a load graph with ...
