From Airworthiness regulation, the electronic power supply system must meet the requirement of power demanding devices which are used to support emergency evacuation of passengers, during emergency landing, including ditching situation. In this situation, the main power supply is often failure, and battery will supply power instead. However, after ditching, the fuselage structure is often damaged, water will flow over into fuselage, if battery, charge or wires are under water and short circuit, then all the devices which are used to support emergency evacuation will failure to work, and passenger evacuation will be very dangerous. For this problem, this paper researches the ditching floating characteristics of commercial aircraft, especially the leakage time of compartment, time-variation of water level, etc. At the same time, this paper analyzes the time of passenger evacuation. Based on those impact facts, this paper researches the battery layout design method of commercial aircraft.
