The 1,000 is an approximation used for "back of the envelope"
calculations on max. gross weight. In actuality on my A/C the basic
empty weight is 3576.5 lbs. and the max. gross wt. is 4750 lbs.
leaving 1173.5 lbs. useful load (10% margin of error between the book
figures and the estimated figures). You also need to remember that the
zero fuel weight is about 300 lbs. below the max. gross. not that that
is really an issue because you can't go too far on less than 50 ga. so
you would not likely hit that limitation.

The 1337 lbs. on the Piper website probably does not count certain
options. Oxygen? Addit'l. avionics?

These figures that limit the carrying capacity are a real shame. I
would expect that in fact the A/C can carry way over these limits but
since it would raise the stall speed over the max. for the utility
category the max. gross was lowered for certification.

I fly a Seneca V but I don’t expect much difference between the
III and the V except the empty weight. I can legally carry about 1,000
lbs. Of people, fuel or some combination. With a burn rate of about 24
gph you figure how the desired balance within the limitations.

Can anybody tell me what a realistic cruising range is for a Seneca
III with long range tanks a a full load (i.e. six people including
pilot)?

Is the useful load on a Seneca V really ~1000lbs? That's nearly
700lbs less than a II. I know the interiors/air condition/avionics
can take up weight but that's obscene.
