I think Cape Air will be well served by the new TECNAM P2012 Traveller.
My sister occasionally flies from BOS to MVY (Martha's Vineyard), and she said she would fly on the P2012 without hesitation.
Back to the Orenda OE600, remember the rated performance figures were achieved on 100LL gasoline. I don't know the grade of gasoline the current TRACE engine burns.
OE600:
- Performance: 600 hp @ 4,400 rpm takeoff (447 kW), 500 hp continuous (373 kW)
- Fuel Consumption: 0.44 lbs./hp/hr (100LL)
- TBO was established at 1800 hours.
(TRACE Engines have achieved a TBO of 2000 hours).
