When a VOR is Decommissioned

The recent shutdown of the Lake Henry VOR (LHY), which lies northeast of Wilkes-Barre PA (VFR chart at SkyVector here), is an example of how the FAA is handling the gradual decommissioning of VORs. (See also More Details about VOR Shutdowns)

As the latest IFR low-altitude en route charts show, the VOR (at present still depicted on the charts to help pilots become familiar with the new routes) has been replaced by a five-letter waypoint, LAAYK.

Note that the frequency for the VOR (110.8) is now shaded to indicate that the facility has been shut down, as described on p. 54 of the Aeronautical Chart User’s Guide.

A wider view of the area shows that several victor airways or segments of airways have been replaced with T-routes, depicted in blue on charts published by the FAA.

T-routes and their associated G (GPS-based) MEAs are described in AIM 5−3−4. Airways and Route Systems and in “Area Naviation (RNAV) ‘T’ Route System” on page 56 of the Aeronautical Chart User’s Guide (12th edition).

You can expect similar changes as more VORs are shut down over the next several years, leaving what the FAA calls the Minimum Operational Network. That plan at present calls for all VORs in the mountainous regions (essentially the western U.S.) to remain online, while many VORs elsewhere in the country are decommissioned.
