However, instructors argue that CBT 23 requires more discipline. There is no instructor asking, "Are you sure you understand the SELCAL monitor?" You are alone with the software. One note for A330 operators: The VACBI CBT 23 you take today may be outdated by next year if your airline issues a Service Bulletin (SB). For example, the recent SB for A330-300s regarding CVR ED112A upgrades changes the physical button layout. Ensure your airline has updated the CBT database.

In the high-stakes world of commercial aviation, knowledge is not just power—it is the primary buffer against system failure and human error. For operators of the Airbus A330, one of the most versatile wide-body aircraft in history, continuous training is non-negotiable.

Because when you are at FL 370 over the Pacific, and the controller asks you to "SELCAL check," you won't have the VACBI simulation to hold your hand. You will have your training.
