Which exit do ditching stations 16-21 utilize during emergencies?

Ditching stations 16-21 utilize the STBD (starboard) overwing exit during emergencies as part of the emergency evacuation procedure. This choice is based on the design of the aircraft and the strategic placement of exits to ensure passenger safety. The overwing exit allows for a rapid egress in situations where other exits may be compromised or inaccessible, particularly in water ditching scenarios. This exit is positioned to provide an effective evacuation route away from the water, allowing passengers to board life rafts or life vests efficiently.

Using the overwing exit also aids in reducing crowding at main exits, facilitating a quicker and more organized evacuation process. The overwing location is designed for specific circumstances, such as ditching, making it a critical component of emergency protocol, thereby ensuring safety and quick access to escape routes in urgent situations.
