What does the Electrical Distribution Logic (EDL) control?

• A. Opening and closing contactors
• B. Monitoring cabin temperature
• C. Regulating voltage
• D. Controlling hydraulic pumps

Answer: (A)

Electrical Distribution Logic is responsible for switching power paths by opening and closing contactors to connect or disconnect electrical buses and equipment. This logic coordinates when power is routed to different parts of the airplane, handles start/stop sequencing of generators, maintains proper bus connections, and executes protection and load-management actions such as interlocks and load shedding. In other words, it governs the physical on/off control of the electrical distribution network through contactors to ensure the right systems receive power safely. Cabin temperature monitoring is handled by the environmental control system, voltage regulation is managed by the generator and regulator architecture, and hydraulic pumps are controlled by the hydraulic system—areas outside the distribution logic.
