C1 Training (CTR)


The training as center controller takes place on either the Gießen (GIN), Paderborn High (PADH), or Dinkelsbühl (DKB) sector. Compared to the training on Tower and Approach, there is relatively little theory content.

If you decide to train in the Paderborn High sector, the mentors of the RG Düsseldorf are responsible for your training. The following guide describes your training steps in the RG Frankfurt.

All training on Center takes place online, which is why the station must be booked for each training with Training=yes. You should find a controller who can occupy EDDF_N_APP for you.

The solo phase for center lasts a maximum of only 3 months. Since this period is very short, it is important to use the solo phase efficiently. If you know that you will not be able to use part of the solo phase for personal reasons, please inform the responsible mentor before your first training, so that we can plan the solo start accordingly.

Lesson and first training


About 30 minutes before the start of the booking time, you will meet with your mentor and discuss the main differences between Approach and Center. You will also briefly discuss the graphical LoA.

Together with your mentor you will occupy the center sector and control independently under his guidance.

If you have the necessary theoretical knowledge and practical skills you will receive the S3 solo phase. Otherwise, further online trainings will follow until you are ready.


The solo phase runs for only 30 days! Towards the end of these 30 days, you should have gained enough experience to request a CPT preparation training. The Solophase can be extended a maximum of two times for further 30 days. This period cannot be extended even after a failed CPT.

CPT Preparation Training


Together with your mentor you will occupy your exam sector and control it independently.  

If the mentor is satisfied with your performance and your theoretical knowledge, he will give you the "go" for your CPT. 

Since all trainings on CTR take place online, there are no separate final trainings.

ATSimTest C1


Please also note that the ATSimTest C1 is much more comprehensive and demanding than the ATSimTests completed so far. If you have any questions, please contact a senior mentor or the lead mentor of the RG Frankfurt. They will be happy to help you and can discuss the tasks set there with you. For questions about aircraft performance you HAVE TO look HERE. Aircraft performance deviating from this list are not considered correct for the purpose of the ATSimtest. The ATSimTest should be completed at least 5 days prior to your CPT.



In the CPT you show two examiners (ATD examiner and local assessor) that you have mastered the center position. All contents of the center training are relevant for the exam.


Tip: control safely and exactly the way you learned it. Don't try to control the traffic overly cautiously, nor do try to get out to all limits and beyond - the examiners only want to see that you can handle the traffic volume well and as confidently as possible. A perfect CPT is therefore very boring for the examiners to watch. If you should have a major mishap or it's just not your day at all, don't be too disappointed about a failed CPT - of course, you have (mostly after a new CPT preparation training) another try.

After passing CPT, you will apply for the C1 rating.
