BUT have not had any training for 20 years !!!!! I think it is their turn, they have baby sat your like for that time waiting for a new type.
Firstly, I reckon you'd be hard-pressed to find ANYONE in QF who has 747/744/767
AND hasn't had training for 20 years. Such a person would have had to have been one of the first on the initial 744 courses, with 747 & 767 already in the bag. Some of the guys who retired in the last 5 years might've fit that description - but then are we counting DC-4 & 707 too??
More importantly, if anyone like that
DOES exist, they'd be on top of the pile for BOTH the 25% for time since last training, and the 25% for courses per years' service (3 courses/40 years = way less than 1 course/10 years = they'd beat everyone else in).
So, no disadvantage to the old blokes who haven't had as much training as they should for their years of service
