Hi, On the Italian PC map the FIS/FIC area is not depicted as the FIS/FIC tablet maps. The correct airspace is on the tablet, I know that is not easy because the FIR area does not correspond to the FIS/FIC, but would be possible to make the airspace identical on both maps ? regards, Gianni

+x+x+xI don't believe they are FIS boundaries, but they are boundaries between different sectors of Class D controlled airspace, which happen to correspond with the FIS areas. They are appearing differently due to different levels of 'decluttering' filtering between the two devices. No Grahm, the Milano FIR is, divided in 2 area: Milano ACC/FIC and Padova ACC/FIC, the southern boundaries does not follow the boundaries between Milano and Rome FIR due to VHF transmission difficulties. Look at the official map, you will see a green line dividing the FIR boundaries between Milano and Rome starting from left, near Livorno/Pisa, then south of Florence and then to East near Pergola IFR point on the bottom right corner of the map. With solid blue you can see a line dividing the Milano ACC/FIC from Rome ACC/FIC, the line is starting from North of Pisa to South West of Bologna, where is written BOLOGNA CTR, then intersect the Padova ACC/FIC line, then go to bottom right corner of the map and is dividing Padova ACC/FIC to Rome ACC/FIC. Little complicated ? Yes but we must live on that. The center/south of Italy is again complicated, the ACC/FIC area between Rome and Brindisi does not follow the boundaries of the FIR due to VHF trasmission problems because of the mountains. The FIS in Milano FIR is class G have several freq (4) , depending where you are.... Above 2500 ft is CTA D class or TMA A class.  That may be the case, but every one of the lines you annotate in your top image is a Class D boundary, which are visible when you set the decluttering filter to >12500' amsl. As you reduce that filter the boundaries progressively disappear.
Check that the 'decluttering' filters are set to the same values on both your tablet and PC, and you will see the same Class D boundaries. I realise that, but even lower than 10500 (is the limit to see it) we have to use and change freq. depending position, altitude, accordingly. In VFR is necessary to know the FIC/FIS boundary at any altitude and if I set 10500 ft on decluttering options, the screen become to cluttered with area that I can't (A class) or I do not intend to use. Maybe the solution is to increase more options in the Airspace menu like "Show CTA", "Show TMA". For instance, in Italy we have CTA D and A class and all TMA are A only. The decluttering options is difficult to set it up, the choice depend more on Class than altitude.
Thanks for your answer and instructions, Regards, Gianni
