Extra 500
I fly an Allison turbo-prop conversion of the Cessna P210, by O&N Aircraft in USA. The Silver Eagle
It is UK based and N registered for the usual reasons, mainly access to an FAA I/R by the owners.
We get 205kts tas at 19-23000ft (certified ceiling) using about 23-25 us gph.
The Extra looks a good replacement although it is heavier because of the carbon construction, 3000lbs versus 2650 for the P210T, both have the same MTOW.
With the long range tanks the Extra will only have a two person payload but a much lower cabin height due to the 5.5 psi. The 210 has 11000 ft cabin at FL220 with 3.35 psi.
The quoted 19gph of the 500 seems a touch optimistic, as 25gph is normal with the 210 and same engine at normal cruise.
The 210 has the edge on field performance operating normally off a 650 mtr. grass strip at our home base.
We will watch the Extra with interest.
