Frankenstein Flight Approach

The RNAV (GPS) approach makes this a non-issue for pilots with GPS. This approach uses the Terminal Arrival Area (TAA) concept centered on TOPSY. Any arrival on a bearing to TOPSY from 326 degrees counterclockwise to 145 degrees simply crosses TOPSY at 2000 feet and continues inbound. In most of that area they can descend to 2000 feet 30 miles out, with a small segment over the Atlantic at 2100 feet. Cant be terrain out there; must be airspace.

Key Takeaways:

The article details the ILS Z Rwy 24 approach at KILM, a hybrid designed to combine RNAV (GPS) Terminal Arrival Area (TAA) procedures for avoiding mandatory procedure turns with the precision of an ILS.
This innovative approach offers benefits such as RVR 1800 authorization with flight director/autopilot use and includes Airport Surveillance Radar (ASR) minimums, providing a radar-vectored non-precision option.
Despite its advantages, the ILS Z approach notably lacks published localizer-only or circling minimums, an omission that was ultimately due to a simple paperwork error during the initial request.

Regulations often have some statutory morasses that defeat common sense. Yet, sometimes, there’s a blow for the common man and reason wins out—at least partially.

This Plus That

Take the ILS Z Rwy 24 approach into Wilmington, NC (KILM). It’s a hybrid of two other approaches: the ILS or LOC Y Rwy 24 and the RNAV (GPS) Rwy 24. It was requested because the original ILS’s only IAF is the LOM/FAF and has a mandatory procedure turn.
