Desired capability or behavior.
Calculate energy consumption per available seat-mile and per per tonne-kilometer as an output of the Performance subsystem
Suggested implementation.
In performance post-mission, add a component that calculates the metrics:
energy/seat-mile (MJ/paxmi) = total mission energy consumption / (number of passengers * mission range)
energy/tonne-km (MJ/tkm) = total mission energy consumption / (useful load * mission range)
I am suggesting useful load be used rather than passenger + cargo mass as useful load is more generic and broadly applicable to future aircraft concepts that might have unusual configurations, but a simple sum of pax + cargo might be more intuitive for users. Units are given in openmdao format (t is metric ton)
