AMC1 UAS.OPEN.060(2)(b) Responsibilities of the Remote Pilot
CAA ORS9 Decision No. 16
VLOS RANGE
The maximum distance of the UA from the RP will depend on the size of the UA and on the environmental characteristics of the area (such as the visibility, presence of tall obstacles, etc.).
RPs must keep the UA at a distance such that they are always able to clearly see it and evaluate the distance of the UA from other obstacles.
If the operation takes place in an area where there are no obstacles and the RP has unobstructed visibility up to the horizon, the UA can be flown up to a distance such that the UA remains clearly visible, in order that it can be controlled, this includes being able to determine its orientation.
If there are obstacles in the operating area, then the distance should be reduced such that the RP is able to evaluate the relative distance of the UA from those obstacles.
The RP should also consider other factors that may affect the maximum range of the UA from the RP, including the C2 link range.
Ensure VLOS, as defined within GM1 Article 2(7), is maintained at all times during flight.
