Where are the flotation equipment deployment system (FEDS) ditching ladders stored?

The flotation equipment deployment system (FEDS) ditching ladders are specifically designed to be stored below each FEDS hatch. This storage location is intentional, as it provides quick and easy access to the ladders in an emergency situation, ensuring that they can be deployed efficiently and effectively when needed. Each hatch is intended to serve as an exit point during a ditching scenario, making it crucial for the ditching ladders to be readily accessible directly under each corresponding hatch.

The other options may pertain to various equipment storage locations or specific areas within the aircraft, but they do not match the intended design and functional requirement for the FEDS ditching ladders as specified in the aircraft's operation and emergency procedures.
