For VFR flights at more than 3,000 feet above the surface, what is the established rule for cruising altitudes?

The correct answer outlines that for VFR (Visual Flight Rules) flights above 3,000 feet AGL (Above Ground Level), pilots should maintain odd altitudes plus 500 feet when flying on magnetic courses between 0° and 179°. This rule is part of the altitude assignment system established to promote safe vertical separation between aircraft flying in the same airspace.

In practice, this means if a pilot is flying a magnetic course heading of, for example, 150°, they would cruise at an altitude of 3,500 feet, 5,500 feet, etc. This system is designed to ensure that aircraft flying in opposite directions are assigned altitudes that minimize the risk of collision.

The reasoning behind odd altitudes for one set of courses contributes to systematic air traffic control and enhances safety by providing a structured way for VFR aircraft to organize themselves in the sky. By adhering to this rule, pilots can ensure they are maintaining proper distance from other aircraft.

Options suggesting even altitudes or fixed altitudes for all directions do not align with this structured guideline and therefore do not reflect the accepted cruising altitude regulations for VFR flights. The use of odd altitudes for the specified magnetic course range directly supports the operational efficiency and safety of all
