Is there a beep back unit installed at Taree?
One of the requirements for RPT above 9 pax seats or 3500kgs is either an AFRU or air ground radio operator.
This might get more interesting as the report unfolds.
No beep back for TRE itself,however Taree forms part of a common CTAF encompassing Port Macquarie, and Taree. Port Macquarie has a beep back, so AFRU response to that confirms correct freq. in addition to that there is a company procedure in place on ground due to shielding from Port and it's AFRU.
