Md driver, cheers for the link, much appreciated.
I can see where the different interpretations of this come from.
There's no mention of augmenting pilots. The reference to 'cruise relief co-pilots' is presumably about the guys some airlines have who fly during the cruise only - is that correct?? I couldn't find a definition for 'cruise relief co-pilot' in the document, but on page 9 it details their different currency requirements (because they don't takeoff or land during normal ops, so the 3 landings in 90 days thing doesn't apply to them) - which implies that those are the guys they are talking about in para 2.3.
Which leaves para 2.2 for 'normal' co-pilots and says they may log 'all flight time'. Not sure whether this means all the time the aircraft is flying, or all the time they are at the controls flying..
personally, i would rather just have stick time in my total flying hours, not the time in the tail end, but the pedant in me wants to get it right according to the regs..
