Relating to advanced air mobility.

HB 3949 defines "advanced air mobility" as electric aircraft (over 300 lbs) for passenger/cargo transport in urban areas, including eVTOLs. It requires the Texas Department of Transportation to create a statewide infrastructure plan for vertiports (landing sites), develop a guidebook for local governments on zoning, and provide education about these technologies. The bill also restricts local governments from regulating advanced air mobility operations except for airport operators managing airport-specific rules. This directly affects airports, local planners, and future developers of electric aircraft infrastructure. The bill aims to standardize planning and prevent conflicting local regulations across Texas.
