What is the total number of emergency exits on the A220?

• A. 6
• B. 7
• C. 8
• D. 9

Answer: (B)

Emergency exit count is determined by the door layout, including both the main doors and any overwing exits. On the A220, the standard configuration provides seven exits: two forward doors (one each side), two aft doors (one each side), and three overwing emergency exits along the cabin. The overwing exits add necessary egress routes without adding extra bulky door structures, meeting evacuation requirements for this cabin size. A six-exit configuration would miss an overwing exit or one door, while eight would imply an additional exit not typical for the standard A220 layout.
