Abstract： To ensure the normal operation of the onboard system， electrical load analysis （ELA） is a very important step in the modification and upgrading of onboard electronic and electrical equipment. Based on the relevant airworthiness regulations， the process and methods of electrical load analysis are summarized. The ELA analysis for the installation of a spraying device on a certain type of helicopter is carried out， which demonstrates compliance with the relevant airworthiness regulations and provides necessary technical support for the certification of the installation of the spraying device on the helicopter.
