(My comment) The printing of the FZL in the text is a retrograde step. Much easier to visualize on the graphic
(Response) It is easy to visualise on the chart but was a way of reducing the amount of data on the chart area and making the chart less cluttered - a common user complaint.
(My comment) The use of XXX to signify "above 10,000 ft" is a huge loss of information compared to the original F215.
(Response) Data for above FL100 is available on the EUR WAFC chart and it was agreed with CAA that a high cut off (10000 FT/FL100) was preferable to an overlap. The chart top must stop somewhere and 10000 FT was thought to be better than 15000 FT.
