Integrity Design Factors ....

Lets review in detail Integrity Specs
I have not spoken to designer or tech spec
I was informed fuel tanks are in the wings
Surprised it list 298 Gals capacity in specs
That means 149 Gals a wing
Aircraft Fuel is 6 pounds per gallon
Therefore 298 x 6 lbs = 1,788 lbs
or 894 lbs per wing
regards to equal consumption for balaced flight

Empty weight is 5,200 lbs
5,200 lbs + 1,788 lbs fuel = 6,988 lbs
20 passengers x 200 lbs = 4,000 lbs
6,988 lbs + 4,000 lbs = 10,988 lbs
10,988 lbs + 1,000 lbs cargo = 11,988 lbs
Maxium Ramp Weight = 10,000 lbs

170 knots x 1.15 = 197.5 mph
7 hrs n cruise x 197.5 = 1,382.5 miles
1,382.5 / 298 gals = 4.64 mpg
