What is the minimum altitude AGL for daytime visual navigation routes?

For daytime visual navigation routes, the minimum altitude above ground level (AGL) is established to ensure that pilots can maintain visual contact with the terrain and navigate effectively, while also being able to respond to any potential emergency situations. The regulation defines this altitude as 1,000 feet AGL.

This altitude provides a sufficient buffer above obstacles such as buildings, towers, and other terrain features that may pose a hazard, allowing pilots to maintain a clear view of the ground for navigation purposes. Flying at this elevation also gives pilots the ability to manage and respond to unforeseen circumstances, such as needing to divert to an alternate landing location.

In contrast, choices that provide lower minimum altitude levels would not ensure the same level of safety and visual navigation capability, while higher altitudes would be unnecessarily restrictive for visual flight rules, which are designed to allow pilots to fly with visual reference to the ground.
