What is the minimum distance in nautical miles that IRs should avoid charted, uncontrolled airports?

The minimum distance in nautical miles that IRs (Instrument Routes) should avoid charted, uncontrolled airports is set at three nautical miles. This distance is important for maintaining safe separation from potential traffic at those airports, which may not be actively controlled or monitored. The three nautical mile buffer helps reduce the risk of inadvertent interactions with general aviation traffic that could be operating without radio communication or flight plan awareness.

This guideline is especially crucial for military operations, where airspace management is vital for safety and operational efficiency. By adhering to this minimum distance, pilots can ensure they are flying in a safe zone that allows them to react to any unexpected situations, thereby decreasing the chances of mid-air conflicts and enhancing overall airspace safety.
