For VFR aircraft operating between 3,000 and 18,000 feet for over 2 minutes, what are the cruising levels based on?

• A. Wind direction
• B. Magnetic heading
• C. Flight plan filed
• D. Visibility conditions

Answer: (B)

The cruising levels for VFR (Visual Flight Rules) aircraft operating between 3,000 and 18,000 feet are based on magnetic heading. This system is structured to enhance safety by providing vertical separation between aircraft flying in different directions. When VFR aircraft are operating in this altitude range, they use hemispherical cruising altitude rules. The guideline dictates that aircraft flying between 3,000 and 18,000 feet must maintain odd thousand-foot altitudes plus 500 feet when flying on an eastbound course (magnetic headings from 0 degrees to 179 degrees), and even thousand-foot altitudes plus 500 feet when flying on a westbound course (magnetic headings from 180 degrees to 359 degrees). This methodology ensures that aircraft are separated vertically and can effectively manage air traffic, thus maximizing safety and efficiency in shared airspace. While factors such as wind direction, flight plan filed, and visibility conditions may affect flight operations, they do not govern the specific altitude assignment for VFR aircraft in the context of cruising levels.
