Thanks for the answers everyone,
Another question, the guidance FD give says that no leave can be taken for the first six months until the end of the probationary period. As a current type rated applicant I have been told that the training time is fairly minimal, so is this strictly adhered to.
If so potentially it seems that I could be released to the line after about two months or less, then have four months or more of deep night flying etc with no more than two days off in a row to recover at any point.
