Hello,
When looking in the Asobo B737 files, we can see a specific pneumatic outlet type for the starter:
Outlet.2 = Name:StarterLeft #Type:Starter #ConsumptionVolume:3.0 #ConsumptionPressure:17.0
This type of outlet is not documented at all in the documentation:
The B737 example written in the SDK is also incorrect (not the same as the actual aircraft):
Kind regards,
Romain
