What does MCD stand for?

• A. Maintenance
• B. Minimum
• C. Lavatory
• D. Main Cabin Door

Answer: (D)

In aviation, door labels use concise abbreviations to quickly identify where a door is and how it’s used. MCD refers to the Main Cabin Door—the primary door used for passenger boarding and for evacuation if needed. This designation points to the door closest to where passengers enter the cabin, rather than a service door or a lavatory door. The other words listed don’t describe the main passenger entry, so they aren’t the correct expansion of the acronym.
