Private Pilot Private Practice Exam

When flying on a magnetic course of 0º through 179º, a pilot should maintain an altitude of odd thousand plus 500 feet. This altitude rule is part of the VFR (Visual Flight Rules) altimeter settings, which are designed to enhance safety and prevent mid-air collisions.

The reason for this specific altitude is to ensure that aircraft flying in these lower courses are separated vertically from those flying in the opposite direction (180º through 359º). By designating odd thousands plus 500 feet for eastbound flights (0º to 179º), and even thousands for westbound (180º to 359º), this system creates a structured flow of air traffic.

This systematic approach helps to maintain a clear separation between aircraft flying in opposite directions, reducing the risk of accidents. The option of maintaining even thousands plus 500 feet applies to the opposite courses and is set to keep those aircraft at a designated altitude which ensures vertical separation on a parallel path. Thus, choosing odd thousand plus 500 feet for courses between 0º and 179º is the correct practice for maintaining proper airspace safety and organization.
