The UAS International Standard (UIS) is the first universal standard to encompass all sectors of the unmanned aircraft sector to provide greater safety and risk assurance for clients. Based on the International Civil Aviation Organisation (ICAO) guidelines, the UAS International Standard was developed by recognised leaders in the industry, along with the end users of Remotely Piloted Aircraft Systems (RPAS) services, to ensure that our approved panel of RPAS operators are of the highest calibre and prioritise safety and the responsible use of unmanned technology over commercial objectives.
