Oooh! A quiz!
1. C & E, as above
2. C. The FO was concerned, but that concern was completely abrogated by the cheery
by the captain. The FO is deferring to the Captain's experience.
It's not "resignation", as that would infer that he still knew it was a problem, but was resigned to the outcome.
It's not "Invulnerability", as that would mean that he still knew it was a problem, but wouldn't affect him.
It's not "Impulsiveness", as he has made a considered effort to bring it to the Captain's attention.
3. D Errors result from crew decisions. The crew are always considered as a unit - i.e. an error from the captain is not a threat to the FO. It is classified as one or the other - in this case if the captain is sick, and still operating then it is a crew error.
