What type of door is the CRJ 200?

• A. PHASE III
• B. TYPE II
• C. SLIDING DOOR
• D. HINGED DOOR

Answer: (A)

Door designations on aircraft aren’t just about how a door moves; they’re tied to certification and cabin configuration families. For the CRJ 200, the door is designated as Phase III, which identifies a specific door assembly and installation approach approved for this airplane’s cabin layout. That Phase III label reflects the particular design lineage and certification basis of the door, including how it integrates with the fuselage and cabin interior.

The other options describe generic door mechanisms or classifications that don’t capture the CRJ 200’s certified door configuration. A Phase III designation, rather than simply “sliding” or “hinged,” is the name expected in training for this aircraft, because it points to the exact design family used on the CRJ 200.
