Lithium-ion (li-ion) batteries have begun to be used as primary and secondary power sources in the aviation sector. Due to the efficiency of power supply provided by li-ion batteries, they have started to take their place in this field. Although electric aircraft have not yet become widespread, they are commonly used for secondary power supply in emergency phases in both military and civil aircraft. Electrical load analysis (ELA) is one of the most important steps that need to be checked before every flight for each aircraft. Every load added to or removed from the aircraft's electrical system is constantly updated within this analysis. When generators are out of the system, a flight profile is prepared along with acceptances to determine how the aircraft will fare, with the aim of landing the aircraft as quickly as possible. In this flight profile, the goal is to land the aircraft on the ground as quickly as possible. In the conducted ELA, the maximum required time for the aircraft to land in the emergency phase is analyzed to inform the flight crew. In this study, ELA for emergency situations of an aircraft has been conducted. The loads powered from the bus connected to the li-ion battery were modeled using the MATLAB Simulink program. Altitude and temperature data were transferred to the system created with the help of flight test equipment. A flight scenario was determined, and necessary acceptances were made. An ELA was conducted according to military standards.
