Scheduling of several of your training items is at the mercy of outside organisations i.e. JCAB. While it looks like 3-4 months of work, your schedule will not be that smooth. For example arrive and do a week or two of induction then be told your Airlaw / Radio ground training will be in two weeks. Or you complete your line training and your final check will not be for a couple of weeks. Regular interruptions due to the bureaucracy turns 3-4 months of actual work into 6-7 months.
