What procedure is recommended while climbing to an assigned altitude on the airway?

Climbing on the centerline of the airway is the recommended procedure because it ensures that you are following standard flight operations that maintain separation from other traffic and obstacles. Airway centerlines are designed to facilitate safe navigation and ensure that aircraft remain adequately separated from each other while on an airway.

When flying on an airway, following the centerline promotes uniformity and predictability in flight paths, which is crucial for air traffic control to manage traffic efficiently and safely. This procedure minimizes the risk of mid-air collisions and provides a clear reference for both pilots and controllers.

While alternative options suggest varied placements within or near the airway, they may introduce unnecessary risks or deviate from standard operating procedures that are focused on safety and traffic flow. Staying on the centerline simplifies navigation and keeps you within the designated airspace structure that supports vertical and lateral separation from other air traffic.
