'Wraith,
The company I guess don't want to waste their money and training time on slackers and angry ants. Fair enough.
Sooo; there's some limitations/ recalls pertaining to aircraft type. Stuff you probably have a handle on anyway.
The rest is enroute, vol2 pt 2 operational stuff to ensure you haven't just been along for the sandwiches. The questions are usually scenario based, obviously there may be a need to utilise type knowledge if appropriate [eg emergency descent O2 profile].
It is not easily failed.
As fortune would have it, it appears hostile23 is not running the show.
B744 ETOPS questions anyone??
