Stepdowns On the GPS?
Early on I learned that sinking below a critical altitude is one of the most difficult errors for me to correct. This has often left me wondering why altitude guidance from GPS navigators is so minimal. With WAAS it knows my altitude often better than my altimeter, and it can warn me when I’m too close to the ground. Why can’t it tell me when I’m about to bust a step-down altitude on an approach, or what altitude is next, or even what the MEA might be on the airway I’m flying?

Key Takeaways:
- GPS navigators currently lack comprehensive altitude guidance for features like step-down altitudes due to incomplete underlying nav-altitude data in their databases.
- Readers provided insights on approach lighting, suggesting a "decoder ring" for AeroNav chart codes and relating "cutoff angles" (visual shadows) to search and rescue operations.
- Effective checklist management during interruptions is crucial for pilots, with methods like using checkmarks suggested to maintain continuity in critical flight phases.
- Some GPS approaches require manual arming of approach mode prior to Initial Approach Fixes (IAFs) located over 30 nautical miles from the airport to ensure correct CDI sensitivity.
