Which indicator on the RSC activates when there is a fault with the antenna azimuth or elevation hand crank?

The indicator that activates when there is a fault with the antenna azimuth or elevation hand crank is the ANT FAULT indicator. This specific indicator is crucial because it directly relates to the proper function of the antenna system. When the azimuth or elevation hand crank is not operating correctly, it can hinder the ability to accurately position the antenna for optimal performance in tracking and engaging targets. The ANT FAULT alert is designed to notify operators about issues affecting antenna positioning, ensuring they can take corrective measures quickly to maintain the effectiveness of the air defense system.

In contrast, other indicators such as TRANSMITTER FAULT, CRANK ERROR, and POWER FAULT provide alerts related to different components and functionalities. TRANSMITTER FAULT would indicate issues with the transmission capability of the system, while POWER FAULT is concerned with electrical power supply problems. CRANK ERROR may imply a malfunction in the crank mechanism itself but is not specific to the antenna faults that ANT FAULT represents. Understanding the functions and implications of each indicator is vital for maintaining operational readiness in air defense settings.
