121.359(g) For those aircraft equipped to record the uninterrupted audio signals received by a boom or a mask microphone, the flight crewmembers are required to use the boom microphone below 18,000 feet mean sea level.
The microphone in the UFlyMike works with a dead battery in the QC2 headset. Hell, it works even if it's not plugged into a headset at all.
That's correct, the mic in the UFM is unaffected by battery failure, thus negating the application of 121.359(g). Sorry.
Furthermore, excellent CRM! I'd be happy to slide the seat all the way back, put my headset away, and let you do all the work.
