Dave, It is true that there are some similarities in the sylabus. BIs, RIs, FAMS, FORMS... The big difference is that, obviousyly everything is coming at you faster.
RIs in the T34 were a pretty good intro. It is much different flying from Whiting to Crestview at 7,000' with a ground speed of 180 kts compared to flying with a ground speed of 350kts at FL250. Some of the differences like this one are pretty obvious.
In FAMS the idea is to get you to a point where you can safely operate the jet without any coaching. You're still doing Approach Turn Stalls, Clean Stalls, Level Speed Changes, etc. The biggest difference, aside from the speed, is the landing pattern. It is all based on AOA. You are learning to fly a Fresnel Lense (meatball) to a carrier box on the runway. It is unlike anything you may have done prior. The AOA approaches they intro in the T34 are just that, an intro.
Other things that may take some adjustment are flying twice a day, everyday. If you were lucky in Primary you got to fly twice a day, however it was probably more like 4-5 times a week total. Flying twice a day is definitely a good thing.
FORMS are pretty similar at first. The two plane basic sequence is the same as in primary. As you move on you start to do Cruise form as a two plane-lots of fun. Wingovers, barrel rools and high AOB-G loaded turns. Its a blast. You will eventually move on to four plane forms. That is a an adventure in itself, especially considering at any one time 2-3 of the aircraft in the division are student solos.
