Which acronym refers to the main entry door in the cabin?

MCD stands for Manual cabin door MCD stands for Major cabin door MCD stands for Main cabin door MCD stands for Main control device

Correct Answer:

MCD stands for Main cabin door

Explanation:

In aviation terminology, door labels use concise acronyms so crew can quickly identify the correct exit. The main entry door in the cabin is designated as the Main Cabin Door, abbreviated MCD. That makes Main Cabin Door the correct expansion, since it reflects the primary access point used for boarding, deplaning, and emergency procedures. The other phrases aren’t standard terms used to label that door and wouldn’t appear on official markings or briefings.
