Interesting thread.
The current AIS narrow route brief is mentioned several times and it really is an effective tool to use which filters out the "irrelevant" data and presents a manageable set of warnings for the area and height parameters entered.
Which is what the average "sport" pilot needs as say below FL40
True it has odditiies like not accepting ICAO airfield codes as waypoints - I find VOR radials/ditances a quick and easy method.
One irritation is the fact that you don't seem to be able to save a "route" (ie Shoreham-Needles -Thruxton -Shoreham) with a name, just a long string of numbers.
Anyone know of a trick to overcome this?
Finally don't EVER EVER go flying without calling the 0500 number - NO EXCUSES!
