A water evacuation is also known as?

A water evacuation is more accurately referred to as “ditching.” This term specifically describes the process of an aircraft making an emergency landing on water, which is distinct from other types of emergency landings that occur on solid land. Ditching involves careful procedure adherence and the use of lifesaving equipment to ensure the safety of passengers and crew upon entering the water.

In the context of aviation emergencies, "water landing" is sometimes used interchangeably with ditching; however, it tends to be a more general term and does not emphasize the emergency aspect as clearly as ditching does. "Emergency landing" refers to any unplanned landing due to various circumstances and can occur on different surfaces, not specifically water. "Sea rescue" pertains to search and rescue operations conducted at sea, which is a separate process from the action of the aircraft itself landing in water.

Thus, the proper designation for a water evacuation where aircraft deliberately land on water due to an emergency is indeed understood within the aviation context as ditching.
