Interesting discussion but probably a moot debate. After running the
numbers on my aircraft with an empty weight of 2370#, full fuel of 110 gallons
(660#) and four 200# adults; 60# of luggage I get a gross weight of 3790# (my
limit is 3400#). The CG is 94.6 or .10 aft of the aft limit. Any more weight is
going to have to be airframe related and I don't know how you could stuff
anything more into this airframe than I have. Now the person asking the question
has probably never flown a IVP with four adults but you probably wouldn't want
to do it for very long. Its not that comfortable IMHO with more than two for a
long trip or three for a short one. If you fill up your baggage area with 100#
of luggage and have 145 gallons of fuel you could get this scenario up to 4127#
and be over 1/2 inch aft of aft CG.
My typical load is two adults, full fuel, 50 pounds of luggage and a gross
of 3300# with a CG right in the middle. I have carried four adults but only
with half fuel and no baggage.
Bonanza gross weights have increased over the years from 2950# on the 1959
K35 to 3850# on the B36TC model with a TSIO 520 engine. OF course, structural
changes were made to handle this as well as airframe changes to accommodate
a larger CG range and higher horsepower engines. All this happened with approved
engineering data and many flight tests.
Hamid says it best.
