The question is why does there need to be a one size fits all? Different a/c are operated in different ways! I don’t believe anyone would endorse a policy that everyone has to complete a common OCU syllabus regardless of type, so why this? If the proposal is to avoid the need for a full OCU for Co to Captain conversion like the letter from Gp says then we (as do the K and I’m sure other types also) already have a course for this. The ‘dual-seat qualified’ package will be the same length and cost no matter when it’s taught. Giving brand new low-houred ab-initio pilots total control of a large aircraft is unnecessary practically - and it isn't the safest way to operate all our aircraft.
