EFFICIENT LIFT
Our biplane configuration has long narrow wings with a short chord line just like a glider, lots of low-drag lift. Wing chord depth is shallow for faster, efficient airfoils.
STRENGTH
The sponsons are attached firmly to the lower-wing, just below the N-struts where they are rock-solid. This is in sharp contrast to other amphibian designs where the sponsons are hung from the high mono-wing, with struts and sometimes guy wires to place them down near the water where they can be effective. However, these arrangements can be much less sturdy, and in some planes are a known and proven weak spot.
NO FLAPS
Because aircraft has very low approach speed, the pilot maintains full control, without flaps or the need for a pronounced flare, to a simple landing on all types of water. Landings on water or land are nearly the same, adding to the operational ease of flying the Super Petrel LS.
