And here in lies a problem. Someone mandates a policy, but it is not written any where, it is assumed that those present on the day will teach all that follow the new procedure. But it is not part of any training course so it doesn't get done. Same happens with out-sourcing, the details get lost. (had to mention that to keep the post relevent to the thread). If CAP 413 is supposed to be the standard, someone better tell the DXB controllers as well as the pilots.
