Turboprop vs turbojet
How much more environmentally friendly is a modern turboprop than an equivalent sized turbojet, in terms of environmental impact?
Roughly 30% lower fuel burn per passenger seat/mile?
Lower flying and less likely to contrail?
Lower flying and releasing emissions at a 'better' height?
A better 'neighbour' in terms of noise?
Is there an environmental argument for making greater use of turboprops for short haul?
How do the new generation of Open Rotor Fans/Unducted fans/Propfans compare?
Any thoughts?
What am I missing?
