Hi all. I just wanted to check my understanding was correct on runway usage. Yesterday I was completing an EGLL-OMDB flight and I used runway 30L at Dubai as this end of the runway was in green, 12R was red, did I use the right approach? I had an incident where another user decided to announce final at the same time as me for 12R and flew right through me. I tried to report but the option was greyed out.
