Although I havent spent much time around GB1s (except for drooling over them while they are on display and flying at airshows) I am always taken aback by how much larger the airplane appears to be in personparticularly, the tall, sweeping rudder that curves down to a sharp point with just enough ground clearance. Max Gross Weight: 2,200 lbs.

With 10 passengers and luggage on board the airplane, it was well under gross weight, but it soon became apparent we could not out climb the ice buildup. The Twin Otter is very powerful, but its fixed landing gear, wing struts and various hinges, plus the thick high lift wing gave lots of places for the ice to accumulate.

Aircraft Weight and Limitations An aircraft’s weight affects inertia and stopping distance. The POH lists landing distances for specific gross weights. Smaller aircraft may only have short field landing distances for maximum gross weight. This can greatly impact landing performance and obstacle clearance.

Meaningful weight conservation comes from the elimination of a spar overlap a two-piece wing would require plus the one-piece design is easier to build accurately. The airfoil is a Harry Riblett shape, giving modernized flow separation on the leading edge for a soft stall yet with good lift and drag performance.
