When is a replacement EMK required onboard?

A replacement Emergency Medical Kit (EMK) is required onboard within one flight cycle if it has been used or if any of its contents are expended. This guideline ensures that medical resources are always available and that the EMK is fully stocked and ready for immediate use in case of medical emergencies. Ensuring that the kit is replaced promptly within the same flight cycle allows for continued compliance with safety regulations and readiness to assist passengers in critical health situations.

Replacement after longer timeframes such as every hour, after every flight, or once a month would not adequately address the need for immediate accessibility of medical supplies when they are used or required. Therefore, the requirement within one flight cycle is both a practical and a regulatory measure to maintain the safety of passengers and crew.
