Cat 2 in operation but Cat 3 actually flown
Well, the following situation happened today. Airport was reporting Cat2 operation in progress. On our charts the minimum for a Cat2 is 102`RA. My captain decided to use the Cat 3a minimum of 50`. I asked him, during the approach briefing if we are going to fly a missed approach if we having no contact at 102`RA. He denied, and said he would continue to the 50`RA minimum because the protection zones and separation would be the same.
Indeed the protection and separation is the same for a cat2 and 3 operation, but are we allowed to just ignore the cat2 "limit" and go straight to the cat3a minimum even though it is not officially in progress?
Thanks for any replies, I greatly appreciate it.
