Highly recommend CRM
When it came to deciding where to do my MCC I had narrowed it down to 3 options. One for convenience, and two based on recommendations. CRM was one of those which was highly recommended by past students and also people within the industry.
All the instructors have a vast amount of knowledge, not just around multi crew operation but the industry as a whole and they are keen to share it.
I learnt so much during my 8 days and (perhaps most importantly) enjoyed the experience.
It may be a benefit to do the JOC course the day before to get a feel for the sim, especially if you dont have any glass cockpit time, but that said I didnt (it was full) and after the first day or so I didnt have any problems.
Obviously I cannot compare this course to any others, but I was pleased that I chose CRM.
