Conventional wisdom holds that every new aircraft design is a result of many tradeoffs. There is always something to be sacrificed. An amphibious aircraft must be slow. An aircraft which meets the Special Light Sport airworthiness certification requirements cannot also meet the structural load stress requirements of a type certified aircraft. A Light Sport certified aircraft cannot also be aerobatic. An amphibious aircraft certainly cannot also do aerobatics. An amphibious aircraft cannot also have a glide ratio and a sink rate that would qualify it to be a Touring Motor Glider. A Touring Motor Glider cannot also land on water and take off again. A Light Sport aircraft which can cruise at 120 Knots cannot also carry 552 lbs. of people and bags 620 Nautical miles (713 statute miles) and still have a 45-minute fuel reserve. An amphibious aircraft cannot land on water with its gear down without a high probability of capsizing. An aircraft cannot land on a runway with its gear up without a big repair bill. An aircraft cannot have a slow stall speed and also have a high cruising speed. Certainly, a light general aviation aircraft cannot accommodate a 6ft 8 inch tall pilot or passenger.
What would an aircraft which could defy all that conventional wisdom be?
Answer- A new class of high technology aircraft heretofore nonexistent. A class of aircraft so strong, so fast, so safe, so efficient, so pretty and so versatile it can deliver every pilot’s favorite kind of flying experience all rolled into one airplane. An aircraft beneath its skin, beastlike in its structural strength but still elegant in its performance and appearance. Such an aircraft would have universal appeal.
What if there really was a class of aircraft like this?
There is now, it’s called the “Seagull Class” of aircraft design. ---Seagull designer Lage Norberg of Svenska Flygfabriken of Sweden is a senior engineer having provided engineering services for companies like Boeing and other aerospace defense companies. Lage and his two engineer sons Staffan and Tomas worked together to create this new class of aircraft. At Svenska Flygfabriken they are comfortable describing cruise speed in terms of nautical miles per hour rather than statute miles per hour. Something promoters of most amphibious aircraft like to avoid in their advertising. This new class has only one member. The Seagull is in a class all its own. It is the only aircraft in the world that can do all these things regardless of price or regulatory scheme. The Seagull is planned to be a Light Sport certified amphibious aircraft but designed to FAR 23 aerobatic type certification requirements. It can be easily converted to its Touring Motor Glider mode by attaching two five-foot wing extensions. It can be trailered. It cruises at 120 KTS, the maximum cruise speed permitted under the LSA category, making it among the fastest LSA aircraft even with its amphibious capability. It can carry two large people and baggage a very long way and for very little fuel burned. It took many years, solving many technological puzzles for the Norberg’s to achieve a design which flawlessly defies all of general aviation’s conventional wisdom. It may be many more years before any competitors can join what they proudly call the “Seagull Class “of high performance light amphibious aircraft. The Seagull is the universal airplane. It does all the things conventional wisdom says are not possible in a single airframe and yet does them all well. Not only does the Seagull perform all these things well, but in most head to head comparisons better than its limited purpose competitors.
Here is the best news of all: The Seagull, with all its advanced technology is an affordable aircraft for someone to build as a kit or to buy as a factory built aircraft. You can trailer it to your local gas station and fill the tank just like your car. Put it in your garage if you like. Put your wife or a friend in the back seat and fly to a distant quiet lake or idyllic island where few others can go. Hang two wing storage pods on the Seagull, fill the thirty-gallon tank to full and take your passenger for as long a cross country trip as most expensive type certified aircraft can with plenty of payload to spare. In no hurry? Attach the two five-foot-long wing tip extensions to the standard wings and turn your Seagull into a 17 to 1 glide ratio Touring Motor Glider and soar silently along with Mother Nature’s own Seagulls.
Svenska Flygfabriken has spared no effort to build in safety features only found in much more expensive type certified aircraft. The Norberg’s have even designed some features not found on type certified amphibious aircraft. For example, their proprietary shock absorbing hull to cabin floor “W” shaped longitudinal structure, is a unique safety design feature. This internal structure is designed to distribute stress loads away from the occupants in the case of a hard-vertical impact. Most important of all, they have designed the aircraft to minimize the possibility of the usually catastrophic event of landing on water with the retractable gear in the down position. The most experienced sea plane pilots can still miss the gear up indication on a water landing. The Seagull design, built around keeping the center of gravity in a favorable location relative to the water’s surface, makes it very difficult to capsize the Seagull. And for those times when the pilot is landing on a hard surface and forgets to put the gear down, the Seagull has a built in aluminum skid plate on the bottom of its hull to eliminate the expense of repairing an abraded fuselage. Insurance companies penalize amphibious aircraft owners with higher premiums if their aircraft are prone to capsizing or damaging a prop or engine. It is Svenska Flygfabrikens hope and expectation that insurance carriers will come to view the Seagull amphibious retractable landing gear risk as no higher than that of a conventional aircraft and in some ways less.
So, welcome to Svenska Flygfabrikens website. I encourage all prospective buyers and interested Seagull followers to take a deep dive into the Seagulls design. Look at what the Seagull has to offer compared to competing aircraft. Take the time to make performance comparisons. See if you can find another aircraft design anywhere in the world that can do all the things the Seagull can do. I believe once knowledgeable of all the Light Sport aircraft offerings on the market and having filtered out all the expensive hype, the educated buyer will consider the SeaGull the best value and by not a small margin. While it is true flying the Seagull is nothing but pure joy and fun, it is no toy. Conventional wisdom aside, the Seagull is a real airplane that can take you where you want or need to go with speed, an unusual level of safety and without the usual tradeoffs you would expect to find.
