Continue reading →: Archer Aviator: A Pilot’s Beta Review of AI Radio TranscriptionTL;DR: I’ve been beta testing Archer Aviator — a first-of-its-kind app that transcribes ATC radio calls in real time, entirely on-device, using GPS and ADS-B to add context most transcription tools can’t. It’s built by Archer Aviation, the eVTOL company behind the Midnight air taxi, not a traditional avionics shop.…

Oshkosh dorm bookings open early and go fast, and if you wait until you’re sure you’re going, you’re not going. So…

A failure mode analysis of dual GSU 25 vs. GSU 25 + G5 in the Garmin G3X ecosystem — including what happens to the autopilot, and what the brand-new AXIS launch tells us about how Garmin itself architects redundancy.
