I've always wondered about the Production Rate for some aircraft, especially in the earlier era. Both of Il-18D and Tu-114 have a capacity of 122 and 220 respectively. But the production rate for both of this aircraft is Once per 3 weeks instead of 1 or 2 judging by its passenger capacity. Is there any other factor that affected the production rate of aircraft other than passenger capacity? Could we adjust the production rate to Once every 2 weeks?
Thank you.
