First, we checked with Garmin and their equipment actually decodes the Morse code identifier rather than rely on GPS and the tuned frequency to look it up in the boxs database. So far, so good. We next checked with Mark Kolber, our regs guru, and he pointed us to AIM 1-1-3.c. That paragraph talks about navaid identification in general, pointing out that merely hearing Morse code isnt enough because it could be transmitting TEST. Likewise, live voice transmissions from FSS or ATC dont indicate a valid navigation signal. The prize, though, is in the paragraphs last sentence, If your equipment automatically decodes the identifier, it is not necessary to listen to the audio identification. So, Rick, youre right. If the box decodes and displays the Morse code identifier, you can rely on that.

Key Takeaways:

• Pilots are not required to audibly confirm Morse code identifiers for navaids if their avionics automatically decode and display the identifier, as per FAA AIM 1-1-3.c.
• Significant concern exists over the sole reliance on GPS for primary navigation, especially given increasing jamming, highlighting the urgent need for a robust, primary-level backup system like modern eLoran.
• FAA regulations (91.113) are unclear regarding right-of-way between an aircraft on a 45-degree entry and one established on downwind in a non-towered pattern, with experts divided on the interpretation, ultimately emphasizing collision avoidance.
