What is the maximum current load drawn by the anti-ice system?

The maximum current load drawn by the anti-ice system is indeed 253 Amps, which is significant because it reflects the system's capability to deliver the necessary heating to prevent ice accumulation on critical surfaces like the wings and tail. The anti-ice system must operate efficiently in demanding conditions, which requires a substantial amount of electrical power.

Understanding that the anti-ice system needs to maintain a specific operational temperature is crucial for safe flight operations, particularly in adverse weather conditions where ice can form rapidly. This high current load indicates the system's robustness and efficiency in providing effective ice protection, essential for maintaining aircraft performance and safety.

The other options represent much lower current loads, which would be insufficient for effective anti-ice operations. An understanding of electrical load management in aircraft systems highlights the importance of knowing these specifications to ensure that the aircraft's electrical systems can adequately support all operational demands.
