How wide is the protected airspace associated with RNAV T-routes?

The protected airspace associated with RNAV T-routes is defined as extending 10 nautical miles on either side of the centerline. This width is established to ensure that aircraft flying along these routes have sufficient lateral separation from other airspace users to maintain safety and efficiency in navigation. The 10 NM buffer provides a margin that allows for deviations that might occur due to factors such as wind drift or navigation inaccuracies while still maintaining overall air traffic management objectives. This protected area is critical, especially in busy air traffic corridors, as it helps to minimize the risk of conflicts and enhances the reliability of the RNAV T-routes for both IFR (Instrument Flight Rules) and VFR (Visual Flight Rules) operations.
