An assembly for an aircraft includes an aircraft electrical distribution bus, a battery, and a control system. The battery includes a plurality of battery strings. Each battery string includes a string contactor. The control system is in signal communication with the string contactor of each battery string. The control system is configured to control a position of the string contactor of each battery string in a closed string position or an open string position. The control system is configured to: detect a fault in a faulted first battery string of the plurality of battery strings and position the string contactor of the faulted first battery string in the open string position, in response to the detected fault in the faulted first battery string and maintain the string contactor of at least one unfaulted second battery string of the plurality of battery strings in the closed string position.

System and method for controlling an aircraft electrical distribution system

An indication system for a hybrid aircraft power plant including an electric motor and a heat engine for driving an air mover configured to propel an aircraft is provided. The indication system includes a display providing a display area and a computer operatively connected to the display. The computer is configured to cause a first visual indication to be generated in the display area of the display. The first visual indication indicates a current amount of energy stored in a battery powering the electric motor of the hybrid aircraft power plant along a scale. The computer is configured to cause a second visual indication to be generated in the same display area of the display. The second visual indication indicates a remaining run time for the electric motor based on the current amount of energy stored in the battery.
