The problem is with a new software update that was just installed. I just flew a 190 trip and had 3 delays because of the enw software. The new software is required to for the CATIII certification. The company is talking about pulling the new updates until the bug can be found and solved. Pilots have reported distance errors on flight plans, false ILS indications, ACARS disruptions and failures, and some other problems. Those problems alone will cause a failure in recieving CATIII certification but I would wager a fix will introduced in the next week or so and they will be back running at the reliability they where running at.
