Turbine engine an alternative for small aircraft?
As discussed, the availability of AVGAS will be a problem in future. Alternatives are sought in diesel and electrical engined aircraft.
Why is the turbine engine no option for smaller aircraft (e.g. C172, PA28)? I've seen some small jet engines (designed for gliders).
Is it because of the relative slow speeds (< 150kts) of the aircraft?
Is it because of the relative low altitudes (< FL100)?
I was just wondering.
