Frankenstein Flight Approach
Mixing two approaches on the fly is verboten. However, the folks in Oke City have the authority to graft twenty-first century design onto an approach system from 1938.
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. Canít be terrain out there; must be airspace.
