RotorLab is an Iowa-built software platform for organizations that design and build their own uncrewed aircraft. It connects an aircraft's engineering design to its flight logs, maintenance history, component life, pilot currency, and the regulatory evidence required across 11 jurisdictions, including the FAA. When an operator builds the aircraft, no manufacturer supplies an airworthiness record. RotorLab generates that record and makes it defensible. Developed and headquartered in Dubuque, serving drone manufacturers, public safety agencies, and education programs, including Loras College.
