I know that new EZY 73-300 pilots are able to do their 73-700 rating after 6months. They then have to fly twenty consecutive sectors on the -700 to be able to get their dual rating.. .. .I had heard that EZY had been making enquiries as to the feasibility of their pilots holding a 73 and A319 dual rating. This sounds like it would be a bit of a nightmare operationally, but is it at all feasible, or legal for that matter?
