Where should No3 coordinate evacuation via both MEDS?

No3 should coordinate evacuation via both MEDS between rows 28 and 29 because this location is typically chosen based on a strategic assessment of the aircraft layout and passenger distribution. The area usually provides sufficient space and accessibility for quick evacuation while also remaining clear of potential hazards such as emergencies at the front or back of the aircraft.

In many instances, the middle section of the aircraft allows for efficient movement without congesting exits that may be further forward or back, especially if those areas may have smoke or debris blocking the way. This choice optimally balances the need for safety and effectiveness in guiding passengers towards the exits, as well as facilitating the overall evacuation process in line with safety protocols.

Additionally, this position aligns well with typical protocols which often designate the middle of the cabin as an effective point for coordinating such actions, mitigating the risk of crowding at the primary exit doors.
