The present invention discloses a civil airport navigational lighting aid flight verification method based on an unmanned aerial vehicle technology. The method is characterized by verifying and reporting the colors, the optical variability and the brightness change of different elevation angles of the navigational lighting aids, involving an unmanned aerial vehicle equipped with a light induction sensor, a GPS and a wireless data exchange transmission device and an airport runway precision approach path indicator (PAPI), and comprises a linear flat flight verification method, a curved flat flight verification method and an approach flight verification method. The novel civil airport PAPI light flight verification method of the present invention can realize the flight in the manners of the linear flight, the curved flight, the hovering reciprocating flight, etc., with the help of the flight characteristics of the unmanned aerial vehicle, and by being different from the characteristics that the flight speed is fast, the observation position is dynamic and fuzzy, the flight line is single and is not flexible, etc., when a conventional manned vehicle carries out the light flight verification on the PAPI, can occupy the better observation positions, and enables the observation data to be quantified more fully, more accurately and more objectively.
