... seems that he'd have helped more by making sure the memory item of disconnecting FD was accomplished.
In that context, "We've losts the speeds" doesn't appear to have had any relevance to "IAS doutuese", and as that item wasn't sought in the QRH (at least no mention made), the PNF became concerned with -
(a) how the aircraft was being handled;
(b) the necessity to get the Capt back ASAP.
Unfortunately, the whole episode can be placed into similar categories -
- Lack of training in high altitude UAS procedures
- Lack of training in high altitude handling
- Lack of CRM training.
Having said that, I and others have noted that a deviation would have resolved any issues, and we would have all continued on blissfully unaware that this accident was still waiting to happen.
