When Textron Aviation unveiled its engine plans for its single-engine turboprop, the Denali, the chosen powerplant, the GE Catalyst engine, was still a work in progress. Its targeted much lower fuel burns coupled with a first for a turboprop—automatic digital power control—made a splash. After delays, the engine was finally FAA approved this year, but in the meantime, Pratt & Whitney has unveiled automatic power control, known as FADEC (full authority digital engine control) on a couple models of its ubiquitous PT-6 turboprop engine. And Daher announced that it was, indeed, using just such an engine on its brand-new Daher TBM 960, which was unveiled at Sun ’n Fun in April.
