Dear Part 107 Aeronautical Knowledge Test Unmanned Aircraft General (UAG) Applicant, Pre-registration with CATS is now open. You may access the Pre-Registration Application atCATS | Pre-register for Part 107 Aeronautical Knowledge Test. The $150.00 test fee will be collected during the pre-registration process. Once you pre-register, CATS will work to secure your testing appointment at your preferred location and date. Once your appointment is secured, we will send you an email confirmation within 10 business days with all information you’ll need to successfully prepare for your test day. If your preferred location or date is not available, a member of the CATS Registration Team will contact you to secure an acceptable alternate appointment. Please note that the following Federal Aviation Administration list of Airman Knowledge Testing Centers, http://www.faa.gov/training_testing/testing/media/test_centers.pdf, was updated on December 3rd, 2015. Since then, there have been changes to the list of available testing centers. Further, the list contains both CATS and PSI Testing Centers. Pre-registration through this application only shows CATS Testing Centers. CATS Testing Centers can be identified with “Site ID” codes that begin with ABS. CATS does not provide test preparation materials and has no comment on test preparation products.
