I am looking at 2 production lines: A320 and 737NG in MT4. Unlike other games, when A320 line tends to get more orders, in MT4, 737NG has more orders. Current orders:
Current year: Mid 2010. Both book solid for the rest of 2010.
Gaps in production in 2011:
Gaps in production in 2012:
A320: ~200 (~50%)
Gaps in production in 2013:
With these stats, one would expect that production of A320 would be cut, B737 left the same or increased.
AWS does the opposite:
A320 Production rate
34 / month (constant)
B737 Production rate:
01-Jan-2005 - 02-Oct-2010 34 / month
02-Oct-2010 - 29-Jan-2011 33 / month
29-Jan-2011 - 32 / month
So AWS did 2 reductions of production while the order queue was solidly booked for B737.
I am watching the B737 line regularly, trying to place orders there. And I can't really find any explanation for these production rate changes.
