When an airway does not cross the lateral TAA boundaries, a feeder route will be established from an 

airway fix or NAVAID to the TAA boundary to provide a transition from the en route structure to the appropriate 

IAF. Each feeder route will terminate at the TAA boundary and will be aligned along a path pointing to the 

associated IAF. Pilots should descend to the TAA altitude after crossing the TAA boundary and cleared for the 

approach by ATC. (See FIG 5

Each waypoint on the “T” is assigned a pronounceable 5

letter name, except the missed approach 

waypoint. These names are used for ATC communications, RNAV databases, and aeronautical navigation 

products. The missed approach waypoint is assigned a pronounceable name when it is not located at the runway 

threshold.
