What is the AC power priority sequence in aviation systems?

• A. Inside, Outside, Crosside, Onside
• B. Onside, Inside, Outside, Crosside
• C. Crosside, Onside, Inside, Outside
• D. Outside, Inside, Crosside, Onside

Answer: (B)

In aviation systems, the AC power priority sequence is crucial for ensuring that aircraft systems receive power in a designated order to optimize functionality and safety. The correct sequence typically follows the logic of prioritizing power sources based on their proximity and reliability. The terms "Onside," "Inside," "Outside," and "Crosside" refer to specific sources of AC power within the aircraft. "Onside" indicates the power source located on the same side as the flight deck, while "Inside" represents power coming from internal systems. "Outside" refers to external power sources, and "Crosside" refers to power drawn from the opposite side of the aircraft. The sequence identified as Onside, Inside, Outside, and Crosside is correct because it represents a logical approach to power management. The "Onside" power is given first priority, as it is typically the most reliable source for essential systems near the pilot's control. Following this, "Inside" power is utilized, which supports various internal aircraft systems. After internal sources, the system can switch to "Outside" power, maximizing available resources before finally drawing from "Crosside," which serves as a backup option from the other side of the aircraft. This priority ensures that critical systems remain operational and minimizes
