Just two years ago, GE’s Business and General Aviation unit announced a new, clean-sheet turboprop and the company said at NBAA-BACE Monday that it will soon run a conforming prototype. The engine is called the ATP for advanced turboprop and although it’s not based on the H-series engines GE bought from the Czech Republic-based Walter Engines in 2008, the engine is being developed and manufactured in the company’s Prague facility.
