Upon passing my original Part 107 Exam in 2016, I was handed an Airman Knowledge Test Report (just one page), which is stamped DO NOT LOSE THIS REPORT. I still have it. I do not recall having to produce that paper upon my arrival at my 2016 recurrent exam. I only recall producing my Certificate card as proof that I was eligible to take the exam. I am now about to schedule my 2020 recurrent exam for this month and I'm not sure I have a similar Airman Knowledge Test Report from 2016 as I haven't looked through my home files yet. Can anyone tell me if one is required to produce this paper when checking in for the recurrent exam, or do you just need to show your Remote Pilot Certificate card as well as other required proof of identification?
