What is the maximum amount of used aircraft that you can buy in a given time frame, and how long dose it take until you can purchase more? I am in one of the beginner worlds and I am trying to figure out how the used aircraft market works. Thanks
See manual

But 2 per day and 3 per 7 days total.
Just to be pedantic, it's actually 2 per day but only 3 every EIGHT days. I know the manual says 7 but it's a long standing bug that I don't think anyone has actually reported.
