An ILS approach chart is really two approaches sharing one chart—except when it isn’t. Sometimes one little detail way upstream makes all the difference.
No Two-for-one here
Fly IFR enough and reading an approach plate becomes something akin to ordering at your favorite diner. You know everything on the menu. When Lorna the waitress tells you theyre fresh out of the sweet potato fries that let you pretend youre getting a vegetable with your triple-bypass cheeseburger, you call for the onion rings instead without asking for your options. Hey, onions are vegetables too, right?
Key Takeaways:
- The ILS Rwy 31 at Salinas (SNS) is notable for lacking both circling minimums and localizer-only minimums directly on its chart.
- This absence is due to a high Procedure Turn (PT) altitude mandated by terrain, which prevented the co-charting of a compliant localizer approach with appropriate stepdowns.
- Additionally, Flight Standards policy prohibits stand-alone precision approaches from having circling minimums, presenting a challenge for pilots needing to circle to another runway after flying the ILS.
