[QUOTE="cosmiccomet74, post: 1930084, member: 4858"] De la página de Pratt & Whitney Canada, todos los modelos que tienen como grupo motopropulsor a la PT-6 tienen reversa. Y lo otro es que la reversa en todos los motores es una opción. Ejemplo, en el Marcel Dassault Falcon 20 equipado con General Electric CF-700 como las reversas eran complicadas y el avión tiene velocidades de aproximación muy bajas la mayoria de los operadores decidieron no adquirir el avión con reversas y hasta algunos como los que había en la Argentina las desinstalaron. Hablar mal de una PT-6 porque se podría haber comprado Garret TPE-331, es como decir que un BMW es peor que un Mercedez Benz...y tenes un Bento...
