Narrative:

I work as an instructor. We were on an fdk RNAV 23Z approach; executing the missed approach. But since the missed approach point fedit is inside the washington ADIZ; we execute the missed approach to the right. On this approach plate the ADIZ is not marked. I fly here every day so I marked on my approach plate the ADIZ. When I got back on the ground; I was told we entered the ADIZ. It was very busy here in frederick; there were at least 15-20 aircraft in the vicinity of fdk. So the ATC controller from potomac just called fdk unicom and asked the guy at the radio which aircraft is near the location where the ADIZ got violated. So he told them he thinks it was my aircraft. I came back and called ATC and told them what happened. To improve this situation the ADIZ should be marked on the plate.
