What is required for a pilot to fly through an airway?

For a pilot to safely and legally fly through an airway, they must have provided clearance and radar control from the appropriate Air Traffic Control Radar Unit (ATCRU). Airways are predefined routes in the sky that aircraft follow, and they are established for the purpose of transitioning through controlled airspace.

When a pilot is flying in controlled airspace, which includes airways, effective communication and coordination with air traffic control are essential to avoid conflicts with other aircraft and to ensure safety. The clearance from the ATCRU not only grants permission to utilize the airway but also allows the pilot to receive navigational guidance and instructions, which can include altitude changes, routing modifications, and traffic advisories.

While a cleared flight plan is important for overall navigation, it is not the same as having the radar control and clearance that airspace requires, particularly since a flight plan can exist without real-time communication or clearance for specific airways. Similarly, while FAA permission might be a part of the broader regulatory framework, it is the clearance and radar control that are pivotal for the immediate operation within the airway. Compliance with visual flight rules is unrelated to the specific requirements for flying through designated airways, as they pertain more to weather conditions and visibility rather than the procedural
