MOSAIC Explained
October 18, 2025 at 4:00:00 PM
Outline:
Overview of MOSAIC
Summary: MOSAIC modernizes the Sport Pilot framework, removing outdated restrictions and introducing new privileges to reflect current aircraft technology.
Effective October 22, 2025.
Expands the definition of light-sport aircraft (LSA).
Removes weight-based limits — focuses instead on stall speed (<59 KIAS Vs1).
Introduces flexibility for aircraft with retractable gear and variable pitch propellers.
Adds night flying privileges (with BasicMed or 3rd Class Medical).
Key Takeaway: MOSAIC represents the most comprehensive reform to Sport Pilot operations since the certificate’s creation in 2004.
Eligibility Requirements
Summary: Sport Pilot applicants must meet revised baseline qualifications emphasizing accessibility and simplified medical compliance.
Minimum age 17.
Must hold a Student or Recreational Pilot Certificate.
Must be able to read, speak, write, and understand English.
Must pass a knowledge and practical test endorsed by an instructor.
Acceptable medical standards include a U.S. driver’s license, BasicMed, or FAA medical certificate.
Instructor Tip: Verify the medical pathway early — it determines whether night privileges can be exercised
Aeronautical Knowledge Requirements
Summary: Ground training or home study must cover all required areas of aeronautical knowledge under the updated MOSAIC framework.
Must complete ground instruction or an FAA-recognized home study course.
Includes NTSB reporting requirements and use of AIM/AC guidance.
Must demonstrate proficiency in VFR navigation using pilotage, dead reckoning, and GPS.
Covers weather theory, recognition, and avoidance including windshear.
Emphasizes ADM (Aeronautical Decision-Making) and Risk Management principles.
Common Mistake: Students often overlook preflight weather planning and performance computations — both are now explicitly required areas.
Flight Proficiency Requirements
Summary: Flight proficiency tasks parallel Private Pilot maneuvers but emphasize Sport-level operational safety and simplicity.
Includes preflight preparation, procedures, airport ops, and pattern work.
Must demonstrate takeoffs, landings, go-arounds, performance, and ground reference maneuvers.
Must perform slow flight, stalls, and emergency operations.
Includes navigation, postflight, and operational review.
Proficiency check option for airplanes/helicopters is eliminated — must take a checkride with DPE or ASI.
Key Takeaway: Proficiency checks transition to formal checkrides — ensuring standardized evaluations across all Sport Pilot categories.
Aeronautical Experience Requirements
Summary: Minimum flight experience remains concise but structured to ensure real-world readiness for solo and cross-country operations.
20 hours total flight time minimum.
At least 15 hours dual instruction in a single-engine airplane.
2 hours cross-country training and 10 full-stop landings required.
2 hours prep within 2 calendar months of the practical test.
5 hours solo, including one 75 NM cross-country with two full-stop landings and a segment of at least 25 NM.
Instructor Tip: Document solo distances carefully — they must meet the updated cross-country definitions for checkride eligibility.
Sport Pilot Privileges
Summary: MOSAIC broadens Sport Pilot privileges, bringing them closer to Private Pilot capabilities.
May share expenses on a pro rata basis.
May fly aircraft with Vs1 ≤ 59 knots.
May perform aerial towing, training, or aerial survey work (for compensation, with proper authorization).
Private through ATP certificate holders may exercise Sport privileges using only a driver’s license medical.
Key Takeaway: MOSAIC expands what Sport Pilots can do, creating more real-world utility and reduced medical barriers.
Limitations
Summary: Sport Pilots still face operational boundaries designed for safety and simplicity.
Cannot carry passengers or property for hire or operate “in furtherance of a business.”
Limited to one passenger maximum.
Cannot fly outside the U.S., above 10,000 MSL or 2,000 AGL, whichever higher.
Night flight allowed only with endorsement and BasicMed or 3rd class medical.
Restricted from Class A airspace and Class B/C/D unless endorsed.
Aircraft must have ≤4 seats and comply with operating limitations.
Common Mistake: Forgetting that VH (maximum continuous level-flight speed) endorsements are required for aircraft >87 KCAS.
Endorsements and Special Authorizations
Summary: Endorsements now govern privileges once assigned by proficiency checks — streamlining upgrades and new aircraft operations.
Retractable gear, variable pitch, and simplified controls all require instructor endorsements.
Operating speed endorsements (for >87 KCAS aircraft) now mandatory.
Class B/C/D airspace endorsements follow proficiency-based training.
Some “Dirty Dozen” Class B airports (per FAR 91 Appendix D) remain prohibited.
Additional category/class privileges require a practical test (DPE/ASI) — not just an instructor proficiency check.
Instructor Tip: Maintain a digital endorsement log — MOSAIC adds multiple one-time endorsements per make/model.
Related FAA References
Summary: New Advisory Circulars (ACs) accompany MOSAIC to guide implementation and training.
AC 61-146 – Sport Pilot Certification and Operations.
AC 61-65K – Certification: Pilots, Flight and Ground Instructors (endorsements).
FAA MOSAIC Article and official PDF resources available on FAA.gov and Dropbox links provided.
Key Takeaway: Always reference current AC versions — pre-MOSAIC editions will not align with new rule structures after October 2025.
Instructor and Student Resources
Summary: MOSAIC training integration begins with updated FAA guidance and private study tools.
Updated CFI and Sport Pilot training materials forthcoming from FAA.
CFI Bootcamp resources:
Emphasize structured audio + visual training for MOSAIC-era certification prep.
Instructor Tip: Pair new FAA AC guidance with Smart Study Pro modules to streamline transition to MOSAIC standards.
Final Key Takeaway
MOSAIC transforms the Sport Pilot certificate into a more capable, flexible, and relevant pathway for modern aviators.The focus shifts from arbitrary aircraft weight limits to performance-based criteria, enabling pilots to fly more complex aircraft safely — with clear training, medical, and endorsement guidance to match.
