It seems like for every "Minimum Decent Altitude", we have to add "XX ft" in MDA on APPCH Page to compensate the altitude lost during go-around right?
However, my colleagues argue that it's no need to add up if the state authority accept go around at MDA. Can the state overrule the Annex 6?
Anybody has any reference documents? My colleagues need "book said"
Your colleagues need to give you "book said" for "state authority"! If they cannot, then MDA is MINIMUM descent altitude! IF you think your can commence go-around at MDA without descending below MDA, then feel free.
Where do you get the "it seems"?!? What do your Flight Handbook and Operations Manual and "state authority" say?!?
Unfortunately, they speak louder. Actually they are more senior!
Then they should be more knowledgeable and able to show you the regulations they believe they rely on!
