Isn't this a training issue?
IT CERTAINLY IS!
Trouble is those that conduct the training are not across the subject. You only have to look at the differences of what is taught between flying schools and even RPT operators and how in practice they interact in the system.
Some years ago it was proposed by one segment of industry that all reports on CTAFs etc relating to inbound and outbound calls should use compass quadrants rather that bearings or radials so as to keep it simple. CASA did not understand and did not take up the recommendation. Same seems still to apply. Not the same since the days when the FOI's actually went flying!
CASA fail to understand these procedures and many operators have developed their own to cater for the situations that they encounter every day. Trouble is those procedures are not all the same and others think because the RPT do or say something it is correct and copy. If they understood the system they would know.
On the other side of the coin, many pilots talk far too much, which in itself shows a degree of ignorance of how it is all meant to work. Another failure of the training schools/departments.
