Since we have been in EASA and in some cases out of it. A good many CPL and ATPL holders have been exercising PPL Instructional privileges with a Class 2 Medical Certificate. The CPL privileges are only required to teach for a CPL licence, not for a rating attached to it. Some EASA States have not gone along with this leading to the clarification in one of the recent amendments. I have been alternating from Class 1 to Class 2 ever since obtaining a lifetime licence in 2013.
