How would you change the Cessna 172
Firstly, sorry if this is not considered a tech Q.
I am currently conducting an investigation into how to improve the Cessna 172 design (about 60 years old!), taking inspiration from 'next generation' designs such as the Diamond DA40.
I would like to have any of your insights into how you think it would be possible/desirable to change the design (eg. composites/new engine/ higher cruise speed etc). Obviously I need to take into account that all aircraft design is a compromise between performance/price/maintenance etc, but I would value other people's opinion.
Thanks
