Savings from Fewer Engines
Anybody got any idea - however rough - how the puchase and maintenance costs of eg a CFM56/IAEV2500 compare with a PW4000/GE CF6?
I'm interested in how much you save by reducing the number of engines.
I'm assuming the fuel cost and drag per megawatt are similar although I suspect weight per Mw drops if you have fewer but larger engines.
