Question about aircraft coming out

Hi! Just wondering if aircraft come out in AE the same time they came out in real life. For example, the first A320NEO order was made on 1 December 2010, so is that when it comes out in AE?

Aircraft come out at a random date within the year they came out in real life. Preorders will randomly open between 1 and 3 years before the aircraft comes out.

Thanks!
