When I looked at photos of the Cessna LSA, it appears bigger than the 152. But from the specs, it's actually smaller:
Model..............152.............162
Overall Height.....8'6"............8'3.6"
Overall Length.....24'1"...........22'9.6"
Wingspan...........33'4"...........30'
Wing Area..........159.5sqft.......120sqft
Wing Loading.......10.5lbs/sqft....11.0lbs/sqft
Cabin Width........39.75"..........44"
Did you notice that the LSA has an optional BRS (parachute) ?
