A few months ago KRJD established the following permanent NOTAM to keep aircraft north of the field: 08/499 - RWY 30 RIGHT TFC PATTERN. 26 AUG 20:45 2020 UNTIL PERM. CREATED: 26 AUG 20:47 2020 In addition, KRJD has the following NOTAM indicating parachute jumps within 3nm of the field: 07/407 - AIRSPACE PJE WI AN AREA DEFINED AS 3NM RADIUS OF RJD SFC-15000FT. 01 AUG 07:00 2020 UNTIL PERM. CREATED: 25 JUL 07:17 2020 As I understand it, the right traffic pattern was established so that airplanes are always north of the field and parachute activity, if present, occurs south of the field. On a few previous occasions I've seen airplanes performing pattern work and remaining north of the field, even during parachute jump operations. Obviously, you should be careful to keep an eye on when jumps are occurring and look out for wayward parachuters, but is it legal and is it okay practice to continue pattern work while jumpers are coming down on the south side of the field? In the past the jump pilot made his announcements but didn't complain about airplanes so long as they stayed on the north side of the air field so I didn't think anything of it. Today, I was making right traffic for 30 per the NOTAM and the jump pilot (not sure if it's a new jump pilot or not) got agitated on the radio that I could be endangering the parachuters by staying in the pattern during the jump operation. As I broke off to the north to avoid any possible further conflicts I asked her, out of confusion, if closed traffic keeping north of the field is not authorized during jump operations, and she said something like "you can't be sure the jumpers will be able to remain away from the field" and I stopped discussing it further. Who is right here? What's the point of the NOTAM for right traffic on 30 if you shouldn't be in the pattern anyway during jump operations?
