Missouri has a state preemption statute that establishes aeronautics as a matter of statewide concern, limiting the ability of cities and counties to enact conflicting local drone regulations. Combined with two major metro areas (St. Louis and Kansas City), a significant national park river system, and extensive agricultural operations, Missouri presents a mix of airspace considerations worth understanding before any commercial or recreational flight.
Missouri State Law: MO Rev. Stat. 305.230
Missouri's aeronautics preemption statute, MO Rev. Stat. 305.230, places authority over navigable airspace within the state under the Missouri Division of Aviation. Local ordinances that regulate drone operations in navigable airspace are generally preempted.
This preemption has limits. Local governments retain authority to regulate drone operations as a land-use matter -- for example, a city can prohibit drone takeoffs and landings from city park property, even if it cannot regulate the airspace above the park. The distinction between airspace regulation (preempted) and ground operations from public property (often not preempted) is important for understanding what local rules are legally enforceable.
For commercial pilots: The practical effect is that Missouri has less local regulatory fragmentation than states without preemption. You are less likely to encounter a Kansas City ordinance that contradicts a St. Louis County rule. However, property-based permit requirements for launching from specific parks and public spaces remain valid.
UAS SkyCheck
Check your exact location: airspace class, TFRs, restricted zones, live weather, and a 0-100 safety score.
What preemption does not cover: FAA rules, Part 107 requirements, national park service restrictions, and federal land management policies are entirely outside state jurisdiction.
Major Airspace in Missouri
St. Louis Lambert International Airport (STL) -- Class B
Lambert is Missouri's busiest airport and carries a full Class B surface area. The Class B extends outward in multiple layers with altitudes defined on the STL Class B chart. For drone pilots, LAANC authorization is required throughout the Class B surface area.
The inner core of the STL Class B has LAANC ceilings of 0 feet in the approach and departure corridors -- no authorized UAS operations even with LAANC. Surrounding cells may permit limited altitude operations. Always check the UAS Facility Map for your specific coordinates rather than relying on distance from the airport.
Kansas City International Airport (MCI) -- Class B
KCI has an unusually compact terminal layout (the single-terminal redesign opened in 2023) but the Class B airspace structure remains large. The Class B layers extend outward at various altitudes. Same LAANC requirements apply as STL.
Other airports
Downtown St. Louis Airport (CPS/SUS), Spirit of St. Louis (SUS), Kansas City's general aviation airports, Springfield-Branson National (SGF, Class C), and Columbia Regional (COU, Class D) each have their own surface area designations. Verify airspace class at your specific coordinates before any operation near these airports.
National Park Service Sites
Ozark National Scenic Riverways
The Ozark National Scenic Riverways encompasses over 80,000 acres of federal land along the Current and Jacks Fork rivers. The NPS interim policy prohibits drone takeoffs, landings, and operations from within National Park Service land. This applies to all NPS-managed land within Ozark National Scenic Riverways.
The riverways are popular with commercial tourism and real estate operators. Operations from non-NPS land adjacent to the riverways may be permissible from an NPS perspective, but the airspace above NPS land requires coordination for any overflights at low altitude.
Wilson's Creek National Battlefield
The Civil War battlefield site near Springfield has NPS management and is subject to the same NPS drone restrictions. Event photography and videography at the site require specific NPS authorization.
Recreational and Commercial Considerations
Agricultural operations
Missouri is a major agricultural state with significant demand for drone crop monitoring, spraying support, and field mapping. Most agricultural operations occur in Class G airspace well clear of controlled airspace -- no LAANC authorization required. Verify before operations near any rural airport.
Filming and real estate
St. Louis and Kansas City both have active commercial drone markets for architectural and real estate photography. LAANC authorization is commonly required for urban operations given the dense airport coverage. Work outward from the city center and check airspace class at each specific property before committing to a job.
Gateway Arch National Park
The Gateway Arch and its surrounding national park grounds are NPS-managed. Drone takeoffs and landings within the park are prohibited under the NPS interim policy. The Arch is also near the Mississippi River approach to St. Louis airports, making the local airspace particularly active.
Part 107 Requirements
Commercial drone operations in Missouri require an FAA Part 107 Remote Pilot Certificate. Missouri has no additional commercial licensing requirement beyond the FAA.
FAA registration: Required for drones 0.55 lbs (250g) or more. Register at faadronezone.faa.gov. One registration number covers all your drones.
Remote ID: Required for registered drones (250g+) unless operating inside a FAA-Recognized Identification Area (FRIA).
TFRs: Kansas City and St. Louis both host NFL stadiums (Arrowhead and Dome at America's Center), MLB teams (Cardinals, Royals), and NHL/NBA facilities. 14 CFR 91.145 TFRs activate for major events. Check for active TFRs before any flight in urban areas on game days.
Pre-Flight Requirements in Missouri
Before any Part 107 operation in Missouri:
- Verify airspace class at your exact coordinates -- run a free check at UAS SkyCheck
- If controlled airspace: get LAANC authorization through any FAA-approved LAANC provider before arriving on site
- Check for active TFRs, especially on game days and during summer fire season
- Confirm no National Park, military, or other restricted zone applies at your specific location
- Review current METAR and 24-hour forecast
UAS SkyCheck checks airspace class, LAANC status, active TFRs, and restricted zones across 11,000+ national zones simultaneously. Free: the first check needs no account, and a free sign-in gives you 5 checks per day.
