Hence wanted to know if there is a legal leeway to descend below MOCA or am I missing something?
If that’s the case, I don’t think it’s legal. My company has had several similar incidents. When we asked where the terrain database came from, it turned out that the person who created the DNP made a mistake, so it had to be corrected. You might want to check with your company — it could be the same situation.
Or maybe they have a more up-to-date database indicating that it’s safe to descend as stated — but if not, that would be quite concerning.
