No i didnt include that. Do they measure the area directly between the leading and trailing edges of wings? Cant see it contributing much to lift at low angles of attack but hey..if thats the accepted convenntion! In this case it would at about 16 sq ft...

Possibly that was a typo..but they then based wingloading calc on the 88 figure and 1000 lb and came out with a number about 50% too light!!! << Did you count the bottom of the fuselage area between the two wing roots? That's usually included in total wing area number, because it makes a "dynamic" pressure difference, similar to what a belly flap does (it creates an upward force vector when deployed).
