Where is the axe located on an aircraft?

The axe on an aircraft is located in the flight deck only. This placement is strategic, as the flight deck serves as a secured area where the flight crew operates the aircraft under all conditions, including emergencies. The axe is identified as a tool used in case of emergencies, such as a fire in the cockpit or any situation requiring an immediate means of access to escape.

By having the axe in the flight deck, it ensures that it is readily accessible to those directly responsible for the safety and operation of the aircraft, allowing for quick response actions in critical circumstances. The other locations mentioned do not offer the required accessibility and security necessary for such an emergency tool, highlighting why the flight deck is the most appropriate area for the axe's storage.
