Abstract
To reduce the climate impact of the turbofan dominated aviation industry, a conceptual propeller aircraft study has been performed to see the a possible reduction in climate impact between the two. The results analysed showed great promise for the reduction of the climate impact at the cost of block time. Additionally, a loss in productivity or fleet size is observed for the climate impact seen. The change in productivity or fleet size is remedied with an decrease in block time, however this results in an increase in climate impact, especially when compared to the turbofan aircraft. Overall it is safe to say that the climate impact can be reduced by utilising propeller aircraft, however either the productivity or fleet size must be changed. Additionally, the costs per flight potentially go up. All for a more sustainable and greener aviation industry.
