While i do understand most of the comments regarding the ATPL theory aspect and the amount of information involved. However, regarding training delivery in condensed time frames, i would like to understand why, for example, type rating courses specifically their ground school/systems classes are also so condensed (1-2 weeks) max. For a modern turbofan aircraft with a high degree of sophistication and advanced technologies, why would providers/authorities intentionally squeeze all that knowledge into such a short time frame?
