At Oshkosh I took the chance to speak with several general aviation leaders — CEOs of top general aviation companies and presidents of leading membership organizations. All have been kind to me with their time and generous with their support for the Sport Pilot concept, but I sensed they didn’t yet accept LSA deep down. Minor questions remained. Today that seems convincingly gone. The same not-100%-certain leaders now chorus, “LSA is here to stay.” *** Evidence of that is again marshaling for AOPA’s season-ending event for general aviation. The D.C.-based organization now counts more than 413,000 members, more than two-thirds of all pilots on the FAA register. The traveling Expo show typically draws well from a region’s pilot population. Action starts October 4-6, 2007 at the Hartford-Brainard Airport (HFD). *** For the third year running AOPA is providing a grouped location for Light-Sport Aircraft right where you enter the airplane display area (SLSA exhibitor list under photo).

Design
Cosmetic appearance, structural integrity, achievement of design goals, effectiveness of aerodynamics, ergonomics.
Pros - Among the best proven designs in the LSA industry. Tecnam brand offers two high-wings and a low wing. Approved under Europe's JAR/VLA program and ASTM consensus standards. All-metal designs trusted by most buyers. All three SLSA designs (Sierra, Bravo, Echo Super) have been updated.
Cons - While addressing the established pilot population, designs do not offer a slate of new innovations. Panels are smaller than some LSA (though glass instruments are easily fitted). Cabins aren't quite as wide as some LSA and panels are conventional looking (though this fact appeals to many GA pilots).
Systems
Subsystems available to pilot such as: Flaps; Fuel sources; Electric start; In-air restart; Brakes; Engine controls; Navigations; Radio; (items covered may be optional).
Pros - All the Tecnam line offer a full range of systems, some at additional cost. Electric flaps and trim can each be infinitely adjusted with panel indicator. Center mounted hand brake with parking feature. The Rotax 912 engine provides electric starting and power output for onboard electronics.
Cons - Full engine cowling must be removed for maintenance. Also, crowded working on instruments via the cockpit. Hand brake is less well accepted by general aviation pilots; could affect resale value. Fueling the Bravo and Echo Super requires a step or ladder (as with most high wing designs).
Cockpit/Cabin
Instrumentation; Ergonomics of controls; Creature comforts; (items covered may be optional).
Pros - Dual throttles likely appreciated in the training environment (where Tecnam designs could do well). Excellent visibility in all models; even high wings have full side windows. Interior appointments will please any pilot used to common general aviation interiors. Easy entry and exit from high wing models. Sliding canopy on the Sierra can be opened in flight. Seats adjust.
Cons - While wider than a Cessna 172, all Tecnams have slimmer interiors than several other LSA. Loading won't allow much baggage if two large occupants are on board. Entry and exit to the Sierra means stepping atop the wing first; not optimal for older or less capable pilots.
Ground Handling
Taxi visibility; Steering; Turn radius; Shock absorption; Stance/Stability; Braking.
Pros - Tecnam reveals its microlight heritage with a hand brake that most ultralight pilots will accept. Parking feature on brake handle. Plenty of ground clearance for less optimal surfaces. Good steering precision. Sturdy gear appears up to flight instruction operations.
Cons - Not a super-fast handling aircraft (though most pilots don't prefer too-light or -responsive controls). No other negatives; excellent control characteristics.
Takeoff/Landing
Qualities; Efficiency; Ease; Comparative values.
Pros - Very well suited to training operations with conventional takeoff and landing qualities. Flaps are highly effective. High-wing models slip especially well (the Sierra also good but less so than high-wing models). Good climb rate at 1,000 fpm. Good ground clearance should an off-field landing be necessary.
Cons - Like most low-wings, the Sierra has less downward landing visibility on approach. Glide is adequate but less than several other LSA. No other negatives; great landing aircraft.
Control
Quality and quantity for: Coordination; Authority; Pressures; Response; and Coupling.
Pros - Very conventional handling with no control springs to interfere with natural feel. Very good control harmony, among the best in light sport aviation. Dutch rolls went well to sharp angles right from first trials. Steep turns took little additional power and carved nice turns. Superb control predictability.
Cons - Not a super-fast handling aircraft (though most pilots don't prefer too-light or -responsive controls). No other negatives; excellent control characteristics.
Performance
Climb; Glide; Sink; Cruise/stall/max speeds; Endurance; Range; Maneuverability.
Pros - Strong climb rate (1,000 fpm) using 100-hp Rotax 912S engine. High cruise (113 knots observed on installed ASI) yet moderately slow stalls resulting in a very respectable 3.2:1 min/max speed ratio (only a few LSA are better). Climb is reasonably strong at 600 to 800 fpm. Clean design helps reduce fuel consumption.
Cons - Glide not as strong as some sleeker, lighter LSA models. By stated specs, takeoff roll (at 460 feet) is longer than several competitors. A very few other brands offer longer range or lower fuel burn (though most pilots won't care about this margin as Tecnam models do reasonably well).
Stability
Stall recovery and characteristics; Dampening; Spiral stability; Adverse yaw qualities.
Pros - All stalls revealed very modest behavior with no clear stall break even when aggravated. Steep turns held bank angle well, did not tighten even as 45° bank angle. Longitudinal and lateral stability checks proved normal and acceptable. Power adjustments brought expected change in pitch.
Cons - Adverse yaw was notable on the Bravo (though seemed less on the Sierra). No parachute fitted to any Tecnam flown, so no unusual attitude work conducted (Tecnam does offer a parachute as an option).
Overall
Addresses the questions: "Will a buyer get what he/she expects to buy, and did the designer/builder achieve the chosen goal?"
Pros - Tecnam offers one of the most reliable LSA brands; the company is highly likely to remain in business well into the future. Performance and handling packages are well optimized for the typical LSA buyer; package works well in a flight-training environment. Trustworthy construction of all metal; excellent fit and finish reported by most buyers.
Cons - Italian-based distribution with only dealers and no committed importer cause some buyers to wonder about long-term support (though this could change if Tecnam follows through with a one-time plan to assemble in the USA). Priced toward the higher end of all LSA models, well past $100,000.
Before Cessna announced its light-sport aircraft (LSA) prototype, the Wichita, Kansas-based aircraft manufacturer investigated the airplanes produced by Costruzioni Aeronautiche Tecnam, aka Tecnam. Cessna’s interest was likely stimulated by Tecnam’s 50-year history of aircraft manufacturing. The company traces its roots to 1950 and the P48B Astore. You may also be familiar with its twin-engine Partenavia series of aircraft that emerged in the 1970s. The Pascale brothers founded Costruzioni Aeronautiche Tecnam just after World War II, but the company was reorganized in 1986. Based today in Casoria, Italy, Tecnam is a large operation with 36,000 square feet of facilities near the Naples Capodichino airport. A second facility is located in Capua, where the final assembly line is adjacent to an airport where flight tests are conducted. “Professor” Luigi Pascale, the 82-yearold patriarch of Tecnam, remains the guiding light of the company. He reportedly still does all first flights of Tecnam airplanes. The company’s design approach is backed with the latest Catia V5 software, wind tunnel tests, and close associations with Italian aero institutes and universities.
