RE:RE:RE:RE:RE:Cadence de production - la presse Bbd, airbus, boeing, even if they keep some infrastructure inhouse, are assembling a plane, not producing it.
Producting a plane is a very long process.
The production rate is something very stable because everything you assemble was produced years before by your supplyers.And if you want to increase the production rate, you have first to send a request to your supplyers and hope they are ALL in capacity to do it (Finantialy), and in how much time.
So rate increase is time and cash consuming (Check the cseries...) and depend more on your supplyers (Engines, sub assy, systems), than the capacity of you final assembly line.
For exemple, the narowbody production rate of airbus and boeing was actuallly decided by the production rate of CFM (LEAPX).
Also, because the production rate is very stable, it doesnt make anny sens to analyse the deliveries every months. If there is no deliveryes it just mean there is more planes waiting for deliveries.
