I am amazed re your comment about Maintenance costs being cheaper for a Piston Aircraft.
Who told you that THE TOOTH FAIRY).
With due respect Piston Aircraft run on AVGAS (Petrol) as apposed to Jet Engines which run on Jet Fuel (Jet A1)
The costs of Avgas are somthing like 10 times the costs of Jet A1
I would go back to your source of information re Piston Aircraft and ask him to remove his head from his bottom
