Ali,
Not that straight forward unfortunately, A retired Trg Captain told me that Sim checks etc are a walk in the park for the older guys as they know all the routes, procedures etc that are done on the checks as many of them have done them every 6 months for the last 20 years, and many of them are being tested by guys who they have flown with for the last 30 odd years.
That being said, I would still rather have a real pilot in the cockpit rather than a wet behind the ears fast tracker. Due to South Africa's contract industry however most of the guys moving up have a vast amount of experience in real flying. I think these older guys should fit in to the training role to impart their knowledge, even if it means as a third crew member.
