Ability has nothing to do with it, this is the oil business. It doesn't matter if you can convert to type. We just converted to new aircraft on this contract and had to have 50 hours on type to fly revenue. Same job, same base, same people, but 50 hours of trg/non-rev req'd. A new-hire PIC would need even more.
Time in type is a contactual requirement, that's all.
When converting an FAA ATPL to a licence that uses type endorsements, you need some paperwork that proves you have a type endorsement or equivalent thereof. A buddy of mine in Nigeria needed to dig up an old Saudi licence he hadn't used in a decade. It had the type endorsement on it, his current FAA licence didn't. Without it he was hooped.
Again, it is the oil business tied up in international aviation bureaucracy. Check all common sense at the door.
It's always easier to know the nature of your enemy. If you really want a job with CHC, call them. Be persistent, research where they operate, which base best suits you, all the rest.
Personally, I've never just sat and waited for the autoreply.
