As I’ve written a few times, I see a dichotomy in LSA designs. Landplanes appear to have entered a “mature” phase, where changes are incremental, evolutionary rather than revolutionary, if you will. I see nothing wrong with that. To the contrary, it speaks to an industry that knows where it is going and how to achieve design goals. Electric propulsion is still stirring things considerably (witness several recent articles here and elsewhere) but electric motors can work on landplanes or seaplanes. To my view, it appears the lead in the most innovative design is being done in LSA seaplanes. Perhaps this was triggered by Icon and their A5. The California entry is handsome and well enough marketed to collect many orders. While finally coming to market A5 has been a decade in preparation. This left the door open for more highly innovative entries Meanwhile existing designs such as Searey and Super Petrel have been much refined and have demonstrated meeting ASTM standards with Searey also achieving Chinese Type Design Approval.
