What is "latency" in navigation systems?

Latency in navigation systems refers to the delay between the input of information and the output response. This concept is critical in various applications, including aviation navigation, where timely and accurate data is essential for safe and efficient operations.

When a pilot inputs a command or when a navigation system receives a signal, there can be a certain amount of time before the system processes that information and provides a response or an updated position. This delay can affect the pilot's ability to respond to changes in the environment or make decisions based on real-time data. Understanding and minimizing latency is crucial for enhancing the effectiveness and safety of navigation systems, especially in dynamic and high-speed environments like aviation.

In this context, options relating to the speed of receiving signals, the frequency of updates, and the accuracy of navigational charts focus on different aspects of navigation systems that, while important, do not specifically encapsulate what latency entails.
