NAVAIDS that use L/MF frequencies are depicted in what color on charts?

NAVAIDs that operate on L/MF (Low/Medium Frequency) frequencies are represented in brown on aviation charts. This color coding helps pilots and air traffic controllers easily identify the type of navigational aid being used. The specific choice of brown for L/MF frequencies ensures consistency across charting systems, allowing for a standardized approach to navigation aids that pilots rely on for safe and efficient flight operations.

Other colors on charts are assigned to different types of navigational aids; for instance, blue is typically used for VORs (VHF Omnidirectional Range), while red might be associated with high-frequency aids. The use of brown specifically for L/MF signals makes it distinct and contributes to clear communication within the aviation community regarding navigation and safety.
