Reims F172

Here are my calculations for a Reims Cessna F172M

Weight (lbs) x Arm (Inches) = Moment (Pound Inches)

Basic Weight: 1488.9 x 38.87 = 57873.54
Row 1: 364* x 44.00 = 16016.00
Row 2: 308** x 73.00 = 22484.00
Fuel: 114*** x 48.00 = 5472.00
Baggage Area 1: 25 x 95 = 2375.00

* 13 stones x 14 lbs/stone x 2 people = 364lbs
** 11 stones x 14 lbs/stone x 2 people = 308lbs
*** 19 USG x 6lbs/USG = 114lbs

Totals

Weight: 2299.90 < MAUW of 2300lbs
Arm: 104220.54/2299.90 = 45.32 inches < Max Aft Moment of 47.5 inches according to POH/FM

Close, but within limits with baggage placed in Baggage Area 1 and a maximum of 25lbs and not 28lbs.
