English is not my mother language, but theres something I dont understand. The conditions for discharges in and out of special areas seem to be the same. What am I seeing wrong here?
Hello, Ricardo, you were missing that in .2 (special areas) it refers to regulation 14.7 and not 14. however, added another explanation (in bold green) to it. which adds alarm arrangement and automatic stopping.
