To apply for TT you need a Full ATPL.Even if you have 2000 hours and don't have 500 hours multicrew you arent eligible for a full ATPL.Atleast thats what its like in the UK.
Yes, that's correct. That's what I meant when I said they might be wanting someone who is capable of applying for TT when they have that many hours. I don't think they'd be interested in someone who's got thousands of hours yet still unable to obtain an ATPL.
