Aussie-the augment crew, by SOP, were required to report tired and ready to rest. They are not involved in the performance data-it is a 2 man operation (in actuality the SOP at the time specified that that they not be involved in the pre-departure process -including maybe doing walkaround or similar-due to having to report ready to rest). Self preservation is another issue, but the bottom line is the only reason augment crew are physically in the cockpit for departure is that you can't occupy the CRC for T/O and Landing, and are not allocated a pax seat. It is a 2 pilot cockpit and 2 pilot op.
