For the Overwing Exits, which ABP assignments are correct?

• A. No3 ABPs: 16 and 17 AB; No4 ABPs: 16 and 17 EF
• B. No3 ABPs: 1BC and 2DE; No4 ABPs: 33BC and 33DE
• C. No3 ABPs: 16 and 17 EF; No4 ABPs: 16 and 17 AB
• D. No3 ABPs: 33BC and 33DE; No4 ABPs: 1BC and 2DE

Answer: (A)

Overwing exits rely on two ABPs at each exit to operate the hatch and direct passengers efficiently. The best assignments place these ABPs in the seats closest to the corresponding exit so they can reach the door immediately and provide clear instructions to evacuees.

For the No3 overwing exit, ABPs numbered 16 and 17 in the AB block are the closest to that exit, so assigning them to No3 ABPs makes sense. For the No4 overwing exit, ABPs numbered 16 and 17 in the EF block are the closest to that exit, so assigning them to No4 ABPs is the most effective arrangement. This setup ensures rapid access to both exits and minimizes delay in guiding passengers.

Other pairings would place ABPs farther from the exits or on the wrong side, which would hinder quick door operation and crowd management. Therefore, the correct approach is to use ABPs 16 and 17 in the AB positions for No3 and ABPs 16 and 17 in the EF positions for No4.
