Figure 13.24. Entry Procedures for One-Base TAAs.
13.10.13. Feeder Routes. When an airway does not cross the lateral TAA boundaries, a
feeder route will be established 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 by air traffic control.
13.10.14. Backup Approach. AFI 11-202 Volume 3, General Flight Rules, details
procedures for flying GPS stand-alone and “overlay” approaches, including requirements
for monitoring of underlying conventional navaids.
13.10.14.1. When flying a stand-alone GPS procedure, it is prudent to monitor a
backup approach when available. If the GPS approach becomes unreliable, comply
with procedures outlined in AFI 11-202 Volume 3 General Flight Rules, for missed
approach. If you are in a safe position to do so and are outside the FAF, request a
clearance to fly your backup approach. Do not transition to your backup approach
without a clearance.
