Narrative:

Approaching jalyd IAF from the east we were switched to tower as the aircraft was maneuvering to intercept the IAF and the 12 DME arc. We were then directed to fly the 10 DME arc and report FAF inbound. The aircraft was already in a turn away from the IAF which is 10 DME to intercept the 12 DME arc. The pilot flying (PF) switched to heading select to turn back to intercept the 10 DME arc by using the sia VOR/ 10 DME on the fix page. The controller told us that we were trying to follow the 12 DME arc and we responded that we were correcting back to intercept. We continued on heading select following 10 DME arc and landed uneventfully. I later talked to the tower and told them our database and jeppesen all had the 12 DME arc. He had said the area past 10 DME was a special operating area (I forget the terminology.) I apologized and told him I would communicate these issues and procedures to the company. Our jeppesen and databases need to somehow be updated to reflect this base's procedures and possibly update the station guide and company pages. We really weren't given enough notice to make this happen when we were already at the IAF intercepting the arc from an awkward angle the aircraft was trying to intercept.
