Is WAAS required when flying a Victor airway?

The assertion that RAIM (Receiver Autonomous Integrity Monitoring) is sufficient when flying a Victor airway is based on the understanding of the regulatory requirements and capabilities of the navigation systems in use. Victor airways are traditional airways used primarily for navigation with ground-based aids like VORs (VHF Omnidirectional Range).

To operate safely along these routes, aircraft need to follow specific navigation rules, which can include using GPS with RAIM. RAIM provides a means to validate the integrity of the GPS signal, ensuring that the navigation system remains reliable during flight. It serves as a crucial safeguard, particularly in airspace where GPS might be the primary navigation source.

While WAAS (Wide Area Augmentation System) significantly improves the accuracy and reliability of GPS signals through ground-based reference stations, it is not a mandatory requirement for flying Victor airways. Many aircraft can navigate effectively within the constraints of RAIM alone, allowing for compliance with established IFR (Instrument Flight Rules) requirements.

While utilizing WAAS is beneficial and enhances safety due to its improved accuracy and reliability, it is not strictly required for navigation along Victor airways. Therefore, the emphasis on RAIM as sufficient is correct within the context of regulations governing prescribed routes and the infrastructure in place for
