Went out to Dallas very recently for a Citation II course. On the plus side the sim instructors were very good as were the manuals. Also, its a very nice facility with all the things you need eg. internet access, decent canteen, library. On the down side I thought the ground training needed to be taught in a more enthusiastic manner - it felt like they were just going through the motions. Some of the admin was pretty poor too and the sim itself needed to be replaced as it went wrong far too often. Apparently it was the 3rd level C sim built ie. its very old and done a lot ! Hopefully the Hawker sims are much fresher and more reliable.
