The former lack of TSO was the hurdle. Now everybody can use 'em.
Regretfully, no. QX added a provision to our FOM that any ANR headset must fail-safe when the battery dies, in addition to our TSO requirement. Therefore, the QC is not an approved headset for our operations.
QUESTION: Is it just the UFlyMike adapter that received TSO cert. or the adapter AND Headset?
The TSO certification states:
UFlyMike Aviation Headset AND UFlyMike Adapter.
Also true about the earbud. The QC2 is a mechanical headband that provides ANR and redundant audio capability. The earbud operates independently of the QC2. You don't even need to have it in your ear, just in the earcup so you will know if the QC2 audio has failed.
Wonder how those other headset companies make headsets that NEVER fail and NEVER do so without warning...
The QC2 is used as a mechanical headband. If your company only requires a boom mic, you don't need to use the earbud and may use the audio from the QC2 instead of the earbud.
If anyone asks if the QC2 is TSO'd answer is "no" because no single component of a TSO'd article is TSO'd independently. It would be like asking if the resistors are TSO'd....
Does the QC2 cause any issues, if used, i.e., RF or EM interference? No. Does it alter the electronic circuitry in any way? No.
The TSO'd version is externally identical to all previous versions. Internally, the chanages were minimal. A TSO is about manufacturing standards, not reliability, safety or performance. The performance standards which are described are MINIMUM standards established in the 1950s. The whole thing is ridiculous.
