What is the first step in preparing for ditching procedures?

The first step in preparing for ditching procedures involves donning survival equipment, including a helmet. This is critical because ensuring that all individuals on board are equipped with the necessary safety gear enhances their protection during the landing in water. Wearing survival equipment is an immediate priority as it prepares the occupants for potential impacts or hazards associated with water landings, and it can greatly aid in their survival after exiting the aircraft.

Other aspects of ditching procedures, such as securing loose items or notifying air traffic control, are important and must be carried out, but they come after ensuring that occupants are equipped and protected. The focus on personal safety by donning survival gear first sets the stage for effective and organized evacuation procedures.
