Last Sunday I had the chance to fly a DA-40 XL. (Lycoming IO-360)
Pretty impressive performance really. Quiet 3 bladed scimitar composite prop.
With 3 people and 3/4 fuel we flew 153kts TAS at 5000'.
With 22"MP and 2300RPM 140 kts TAS @ 10 gallons/hr.
Also a usefull load increase of 110 pounds over the regular DA-40 CS.
Integrated autopilot/flight director, active traffic system, nexrad weather...
oh dear oh dear..almost fainted...
