thats cool. I know only 2 things for sure. 1. FMS systems for an aircraft like the CRJ-200 would likely be enormously difficult to program and have it work as in reality. by that I mean I would not know where to begin. 2. flight in such a aircraft without a functional FMS would be completely unrealistic because 90+ % of the time these jets fly IFR flight plans regardless of weather. paso a paso , is right man. después de todo su trabajo, yo quiero ser el burro estúpido que Askes demasiadas preguntas I don't want to be the donkey who asked too many questions.
