Omissions? Errors? I guess they can't get in trouble if they just don't update the information. The reason for that statement. They specifically mention a Canberra.
Omissions and Errors on the part of the FAA for forgetting to update frequencies and other data in their publications. They finally updated New York Oceanic frequency from 132.150 to the 133.500 (it has only been changed for 10 years). Publication errors are human......with the amount of data in the publications - errors and omissions come in. The only way to verify the information (for us - not the pilots) is by listening and tracking. If ARTCC tells a pilot to switch to 133.500 when they are headed to Bermuda - they will switch to 133.500 and not say but the publication lists 132.150 for that area. In reality - we are more picky about the information since we are doing this for a hobby - pilot's job is to fly the aircraft.
