Wow great info how do you know all this?? Also how long does it take to get those out of the way about a year each? i hear enroute is pretty difficult??So, just some info incase people wondered. Once you reach your facility, you'll start working toward D1 certification. Basically training through the FAA is based on scales... D1, D2, D3 and CPC. You recieve a pay raise for each as you move along in your training. So for enroute, you will be assigned a speciality. A specialist is a way of dividing the work load throughout the center. In your speciality, you may have up to 6-9 sectors. D1 entails learning your first two D-sides or radar associate. Next is D2 which requires you to learn all the D-sides. D3 is two R-sides and CPC is all of your R-sides.
