What is the maximum distance indicated by the green MAL bar?

The green MAL (Maximum Altitude Limit) bar typically indicates a safe operating range for aviation communications or navigational systems. In many contexts, the distance associated with the MAL is determined based on operational parameters, safety regulations, and system capabilities.

In this case, the maximum distance indicated by the green MAL bar is 3,500 feet. This is generally interpreted as the upper limit for safe operations under specific conditions, ensuring that all systems and aircraft remain within a range that minimizes risk and enhances navigational reliability. Since 3,500 feet represents this balance of safety and operational performance, it is important for pilots and engineers to adhere to these guidelines.

For reference, the other distances listed—2,000 feet, 3,000 feet, and 4,000 feet—do not align with the established maximum indicated by the green MAL bar in this scenario, as they either fall below the maximum safe limit or exceed it. Understanding these limits is crucial for effective and safe aviation operations.
