Free-Flying

Youre living the good life and working the system-the tax system. You work in Portland, Oregon, with no sales tax, but live across the river in Vancouver, Washington, with no income tax. So, you can at last afford that glass-panel bird. After flying it across the U.S. to bring it home, its finally time to load the last approach of the trip: The LDA-A into Pearson Field in Vancouver (KVUO). Except the approach isnt in the GPS database.

Key Takeaways:

• The LDA-A approach to Pearson Field (KVUO) is absent from GPS databases because its shared localizer with Portland International (KPDX) is incompatible with ARINC coding standards.
• Pilots can work around this by manually tuning the localizer and identifying stepdowns using VOR radials, timing, or by creating custom waypoints based on localizer DME fixes and available database fixes.
• This workaround requires flying "raw data" without database fault detection, and the approach involves other operational complexities like mandatory radar vectors, a high MDA often necessitating a circling approach, and potential conflicts with KPDX operations.
