The factors that affect a company's P/Q rating for UAV drones do not include the average number of obstacle sensors in its drone models, the amount by which the number of extra performance features built into in a company's drone models is above/below the industry average, and the amount by which a company's prior-year expenditures for training the pilots that test its drones after assembly and improving its drone-testing methods is above/below the industry average, the amount a company spends on training its drone-related PATS and improving its drone-related assembly methods. the number of rotors, rotor performance and flight controller features/capabilities, and body frame construction. the caliber of the obstacle sensors, the caliber of the built-in action-capture camera, the caliber of the built-in GPS/Wi- Fi/Bluetooth components, and battery life (maximum flight time per charge). the number of drone models in the company's product lineup, the quality of the camera stabilization device in the company's drones, and a company's cumulative spending on drone-related product R&D.
