Which cruising altitude rule applies to flights heading east?

• A. East flights use even thousands
• B. East flights use odd thousands
• C. East flights can choose any altitude
• D. East flights must fly at or above 10,000 feet

Answer: (B)

The rule that applies to flights heading east is that they must use odd thousands for cruising altitudes. This system is part of the standard regulations for IFR operations, known as the "cruising altitude" rules, which help to maintain safe separation between aircraft flying in opposite directions. For eastbound flights, cruising altitudes will be assigned as follows: 3,000, 5,000, 7,000, 9,000 feet, and so forth up to the higher cruising altitudes. This system enhances safety by preventing possible mid-air collisions, as it keeps aircraft flying in opposite directions at different altitudes, creating established flight levels. In contrast, westbound flights operate at even thousands of feet. Understanding this altitude assignment is essential for pilots to ensure compliance with FAA regulations and safe operation within controlled airspace.
