Is MOSAIC In Your Future?

The STsw evolved from an earlier incarnation of the CT that sported a longer wing, but the change to the "sw" -- for "short wing" -- improved the bird's landing characteristics by reducing its tendancy to float on approach, a product of the CT's clean lines and efficient airfoil.

Key Takeaways:

The FAA's proposed MOSAIC initiative aims to significantly expand the types of aircraft eligible for operation by sport pilots and the scope of permissible operations.
Key changes include removing previous weight and speed limits for Light Sport Aircraft (LSA), replacing them with new definitions like a 54-knot stall speed and 250-knot max level flight speed, enabling sport pilots to fly a wider range of non-LSA and complex aircraft with appropriate endorsements.
The proposal also eliminates the single piston engine requirement, opening the LSA market to electric and other diverse propulsion systems, with the FAA citing the existing LSA safety record as validation for the expansion.

Both the Aircraft Owners and Pilots Association (AOPA) and the Experimental Aircraft Association (EAA) are hailing the FAA’s late July 2023 notice of proposed rulemaking (NPRM) on the long-sought MOSAIC initiative. The acronym stands for “Modernization of Special Airworthiness Certificates,” and both organizations have been working with the FAA on it for years.

The proposal would significantly revise upward the pool of aircraft eligible for operation by sport pilots while also expanding the kinds of operations allowed. For example, the 1320-pound weight and 120-knot top speed limits for light sport aircraft (LSA) certification would go away, replaced with a new definition limiting fixed-wing aircraft to a clean stall speed (V_S1) of 54 knots calibrated airspeed, a maximum level flight speed (V_H) of 250 knots and four seats. A sport pilot would still be limited to only a single passenger, however.
