Hi OFP
These are (if they are from Navtech), the new charts from European Aeronautical Group. To quote their intro splurge in the info booklet my company gave out to us about a month ago;
"The focus of our development has been to create a modern chart specification, taking into consideration recent research and our vast experience as a chart maker.
We believe we have taken a step into the future, bringing you the most modern and easy to use aeronautical chart product in the market.
Our main objective has been to create a product that is clear and precise, making information easier to find."
Not checked it out so don't know if it will be of any use but their website is

The guy to ask Topslide may very well be Patrik Stromqvist, Director, Product Management Charting
