When Are You..

example at Hermiston, there’s no flexibility to establish a NoPT arrival sector at ELN, since this VOR is an IAF/FAF, rather than an IAF/intermediate fix.
According to the FAA chief counsel’s letter mentioned earlier, the DME arc can only be entered from either V-468 from the south, or from V-25 from the north. At this location, all airways that intersect the pub-lished arc meet TERPs criteria for estab-lishing the arc. In many foreign countries, the approving authority publishes all ap-proved methods for joining the arc, similar to the 042-and 055 radials shown on this procedure for arc step-down purposes. The FAA has been urged to update its criteria in this regard, but things move very slowly these days due to budget cuts and early re-tirements of many seasoned technical per-sonnel.
Potential problem
Refer to the Arcata-Eureka, CA ILS Runway 32 and en route chart (on right). This procedure shows how a mistake by the FAA can result in potentially a real problem at a non-radar location. Both charts show Yager Intersection on the localizer. A proper application of both TERPs and charting criteria would require a “NoPT’ route from Yager, since it’s an airway fix that meets NoPT requirements from the southeast.
Also, the approach chart should have a note prohibiting a Yager arrival from the northwest, since a turn from this direction at Yager exceeds the 120-degree turn limit mandated by TERPs (also, a lead radial is required for turns of 91-120 degrees). An arrival over FOT is expected to use the 050-radial feeder route, followed by the proce-dure turn. A DME-equipped aircraft arriv-ing from the southeast on the FOT R-136 would be expected to fly the 20-mile arc.
