Update of frequencies ??
« on: December 01, 2004, 12:03:49 PM »
Was just wondering when and who updates the ARTCC and ACC frequencies? The reason i am asking is that some frequencies are not listed that exist and especially with the ACC's of canad that some frequencies that are listed as low are actually high and vice versa. How often are these frequencies updated ? I am also waiting in anticipation for more ACC charts to be posted especially of the Montreal ACC sectors.
