Readback: October 2019
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 box’s 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 isn’t enough because it could be transmitting “TEST.” Likewise, live voice transmissions from FSS or ATC don’t indicate a valid navigation signal. The prize, though, is in the paragraph’s last sentence, “If your equipment automatically decodes the identifier, it is not necessary to listen to the audio identification.” So, Rick, you’re right. If the box decodes and displays the Morse code identifier, you can rely on that.
