What cruising altitude configuration is appropriate for VFR altitudes when flying in a course of 0-179 degrees?

When flying under Visual Flight Rules (VFR) and maintaining heading courses between 0 to 179 degrees, the appropriate cruising altitude configuration is to operate at odd altitudes plus 500 feet. This rule is outlined by the FAA to help prevent collisions in the vertical plane, ensuring safe separation between aircraft flying in opposite directions.

For aircraft flying on a course of 0 to 179 degrees, the standard practice is to choose odd altitudes—such as 1,500, 3,500, 5,500 feet, etc.—and then add 500 feet to maintain a safe vertical distance from other aircraft that might be operating on the same or a parallel course at even altitudes. This systematic approach mitigates the chance of vertical collisions and enhances overall safety in congested airspace.

The other options do not align with this established rule and could potentially lead to safety issues. For instance, even altitudes + 500 feet would apply to aircraft on courses from 180 to 359 degrees, which would not serve the purpose for the indicated heading range. Options allowing any altitude or only those above 500 feet neglect the structured altitude rules designed to enhance situational awareness and safety for all pilots sharing the airspace.
