The FAA is worried that a faulty power supply, I guess a battery pack, could expire at a not so good moment. I couldn't believe it when he told me (he noticed I use bose). He told me that he would double check and sure enough the next day he told me that yes, in fact it would be happening and rather shortly.
my Stratus 50d has 50db of noise canceling (even more at different freqs) and i can still hear the Gear horn and Stall Horn just fineHmmm. Even with noise canceling I can hear alarms and aural warnings just fine. Some chimes go to the speaker and the headset anyway. Is there any noise canceling that is powerful enough to dampen alarm chimes or verbal aural warnings?
You can find out before you buy it. I think most David Clarks are TSOed. I know Lightspeeds are not.On that note, What headsets out there TSO'd versus non TSO'd?
I realize the "strap on mike" ones are not TSO'd. Are 'most' headsets sold as "aviation headsets" TSO'd?
