AMC1 UAS.OPEN.030(1) UAS operations in subcategory A2
ED Decision 2019/021/R
SAFE DISTANCE FROM UNINVOLVED PERSONS
(a) The minimum horizontal distance of the UA from uninvolved persons should be defined as the distance between the points where the UA would hit the ground in the event of a vertical fall and the position of the uninvolved persons.
(b) As a reference, when the UA is operating in close proximity to people, the remote pilot should keep the UA at a lateral distance from any uninvolved person that is not shorter than the height (‘1:1 rule’, i.e. if the UA is flying at a height of 30 m, the distance from any uninvolved person should be at least 30 m).
(c) In any case, the distance from uninvolved persons should always be greater than:
(1) 5 m, when the low-speed mode function on the UA is activated and set to 3 m per second;
(2) 5 m, when operating a UAS balloon or airship; or
(3) 30 m in all other cases.
