GM1 UAS.OPEN.060(2)(g) Green Flashing Light

CAA ORS9 Decision No. 57

UAS Operated in the Open category must be equipped with a green flashing light when operated at night. UK Class marked UAS will comply with this requirement as part of the class mark design requirements. Non class marked UAS will need to be retrofitted with a green flashing light. If adding an add-on light to a UA, the UAS Operator must ensure it does not cause the UA to exceed the maximum mass, if one is defined. When working out which category to operate within, the total mass of the UA (including an add-on light) must be taken into account. For example, a 249 g UA with a 5 g light added, would not be able to operate in the <250 g part of the Open category.
