Two Up, Two Down

Gemini Sparkle

Key Takeaways:

  • Non-standard IFR procedures at airports like Kingston (20N) and Montague (KSIY) present unique challenges, including complex ODPs, offset final approach courses, and NDB-based approaches, differing significantly from common GPS LPV procedures.
  • Thorough pre-flight briefing is critical to identify and navigate various "gotchas," such as precise ODP interpretation, understanding hold types, anticipating limitations of advisory vertical guidance (LP+V), and deciphering unusual weather reporting methods.
  • Effective GPS utilization requires nuanced understanding and strategic decision-making, including proper use of OBS mode for NDBs, discerning when to follow or override automatic sequencing, and making critical judgments on descent profiles, landing strategies, and potential diversions.

You can fly a lot of IFR these days without encountering anything but GPS approaches with LPV minimums. In this challenge, you’ll fly departures and approaches at two airports where the procedures required are anything but standard. Better brief them well so the gotchas don’t getcha.

Use whatever airplane you like for this challenge, as long as it has a GPS. A WAAS GPS would be even better. Just be sure it’s something you can stay ahead of when things change in a hurry.
