In a scenario where wind is blowing from west to east, which side of the aircraft should be ventilated using wind-assisted ventilation?

Ventilating the east side of the aircraft when the wind is blowing from west to east is effective because it utilizes the wind to aid the ventilation process. The principle behind wind-assisted ventilation involves taking advantage of the wind's natural flow to enhance smoke and heat removal from the aircraft.

By opening the compartments or hatches on the east side, the wind can help push smoke and hot gases out of the aircraft, improving visibility and conditions for rescuers and occupants. This method also creates a differential pressure that can assist in clearing the interior of the aircraft more efficiently.

In this context, the other options would not leverage the natural wind flow effectively. For instance, ventilating the west side would not be optimal since it would go against the wind direction, potentially allowing smoke to be pushed back into the aircraft rather than out of it. Therefore, ventilating on the east side aligns with the principle of maximizing the benefits of wind-assisted ventilation in an emergency scenario.
