Mike,
Whats wrong with covering a bit beyond destination. People aren't all crack navigators, some people do get it wrong, even people who get paid for it.
And saying its another 800 sq miles, no problem for me I just don't want to read Liverpools Notams when I am flying mainly in Kent.
Perhaps this problem can be solved by printing them in Latitude sequence like they used to be. I've never worked out what sequence they print in. In the old days when they printed in latitude sequence it didn't matter if you got all of them because you started 0.5 degrees below your most southerly lat then up to 0.5 degrees beyond most notherly. Usually a concise list and OK it included some which were way out west but at least you aren't picking through north notams to find southern ones.
In brief a narrow route briefing isn't wide enough and an area briefing is too wide. We need something in the middle
How do we talk direectly to AIS to get their view on it.
