GM1 UAS.STS-02.020(3) UAS operations in STS-02 ED Decision 2022/002/R FLIGHT VISIBILITY Point [UAS.STS-02.020(3)](#_DxCrossRefBm1106657003) requires a minimum flight visibility of 5 km to ensure that the remote pilot and/or the AO(s) can adequately visually scan the operational volume and surrounding airspace to detect well in advance any incoming manned aircraft and identify any risk of collision with that aircraft. ‘Flight visibility’ should be understood as the shortest distance from the remote pilot’s position, or from the position of each of the AOs (if employed), at which unlighted objects may be seen and identified at day and prominently lighted objects may be seen and identified at night. It should be considered in all directions. Before starting the intended UAS operation, the UAS operator should gather all relevant information that may affect the UAS flight visibility. Other aspects that should be considered are, for example, the light conditions (including the sun or other intense lights that may blind the remote pilot and/or the AO(s)), the presence of natural or artificial obstacles, the cloud ceiling level, the presence of smoke, etc. ##### GM1 UAS.STS-02.020(3) UAS operations in STS-02 *ED Decision 2022/002/R* **FLIGHT VISIBILITY** Point [UAS.STS-02.020(3)](#_DxCrossRefBm1295819321) requires a minimum flight visibility of 5 km to ensure that the remote pilot and/or the AO(s) can adequately visually scan the operational volume and surrounding airspace to detect well in advance any incoming manned aircraft and identify any risk of collision with that aircraft. ‘Flight visibility’ should be understood as the shortest distance from the remote pilot’s position, or from the position of each of the AOs (if employed), at which unlighted objects may be seen and identified at day and prominently lighted objects may be seen and identified at night.
