Which item must be included in the survival kit on board?

The inclusion of a water bottle in the survival kit is essential for ensuring hydration in emergency situations. In the event of a forced landing or survival scenario, access to clean water can be critical for maintaining health and preventing dehydration. The physiological impact of lacking water can be severe, leading to fatigue, confusion, and ultimately, a significantly reduced chance of survival.

While flotation devices, fire extinguishers, and first aid kits are also important safety items and may be highly specialized depending on specific flight conditions, the necessity of water for sustenance makes it a fundamental component in any survival kit. In many survival situations, particularly those in remote areas or over water, having a reliable source of hydration can mean the difference between life and death. Thus, having a water bottle readily available is prioritized for survival preparedness.
