When making route assignments, use airways and routes consistent with the altitude stratum being used.

• A. Use the shortest route
• B. Use airways and routes consistent with altitude stratum
• C. Avoid established airways
• D. Random route selections

Answer: (B)

Aligning route assignments with the altitude stratum ensures you use airways that are published and safe for the flight level you’re operating at. Each altitude band has its own network of airways designed for reliable navigation, radar coverage, and the required separation standards. When you pick routes that match the chosen altitude, you stay within the published airway structure, which helps controllers provide accurate guidance and maintain proper separation from other traffic and terrain. This approach also ensures the route has validated obstacle clearance and ATC procedures for that flight level. Shortest routes, avoiding established airways, or random routing can lead you off the protected network and create safety and efficiency issues.
