Arrival Procedures

8.

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.

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.
