The co-pilot's VHF 1 transmission at 1244:31 (TGEN 266) is particularly good, IMO, because it is so brief and easily defined: "Recu."
They probably needed another as close to TGEN 000 as possible, in which case there should be a good opportunity at the beginning of the T/O. The CVR transcript shows "Ca roule 296 Q" (probably spoken as "Ca roule deux-cent quatre-vingt-seize quebec"?) with a retro time-stamp of 1240:44, which presumably coincides with a DFDR discrete starting at about TGEN 039.
Brief, knee-jerk acknowledgements are unlikely to be preceded by a pause with the Tx key already open. Transmissions requiring thought might be.
However, what the CVR transcript does not reveal is that (IIRC) the CVR has separate channels for each pilot's Tx, and each pilot's Rx, as well as the area microphone. Therefore, I would expect the co-pilot's Tx channel to pick up the sound of the transmit key being opened and closed. If so, the CVR keying event would be well within the one-second accuracy provided by the DFDR discretes.
Quote from HN39:
"In the html version of the Journal Officiel de la Republique Tomes 1 through 6 are in Appendix VIII, but Appendix no.7 is still missing."
Yes, the HTML version is so much better. Apart from the missing Annexe VIII, the only gripes are the lack of page numbering, and the Habsheim airfield plate being just as blurred as the PDF. The shambolic "Additif" section is not needed. I'm wondering if the PDF might have been created from an early draft of the Report.
