TFDi Design Boeing 717 COG

Recommended Posts

Is it not possible to fly the Boeing 717 with no cargo or passengers? The upper limit for the COG is 34.7, but to get down to a value just below that I have to fill the forward cargo hold (1814kgs) and add 5 passengers! Is that correct, or am I missing something? :huh:

It wouldn't be unheard of to have to fly with Ballast.  There are quite a few aircraft that can't fly around empty. Think of where the wings are, the CG is already sitting really far aft, especially at a higher duel load I bet this aircraft gets really AFT really quick.

The Leonardo Madog is the same way, doesn't like being empty. I had to throw in ballast yesterday to 'ferry' a plane.  You can look at the PMDG 74. The BCF specifically, if I remember they don't like being empty either (atleast in real life). In general the 74 doesn't like light weight and aft CG anyways.

I am a recently retired very frequent Delta flyer, for the last 2 years we have all 717 all the time from MLB. I've seen an empty ferry back to ATL once or twice and every time they load a lot of ballast, just like CRJ 200's with a light load. And they always load it forward, not aft.
