I'm new to SD and am planning a trip from Eastern France to Milan, ITALY.

I really love the graphic interface of your software and how clearly information is depicted.

However, I realize that some information about Northern Italy's class A airspace could be incorrect.

This huge class A around Milan and Turin is very complex and divided into several sectors each having different vertical limits. SD seems not to take this into consideration and shows one BIG class A airspace limited between 2500 ft ( 1500 AGL) and FL 195.

As an example, the actual Class A airspace just East of AOSTA (LIMW) is simply limited between FL 175 and FL 195, but SD shows it limited between 2500 ft ( 1500 AGL) and FL 195.

Another example: the class A over lake Maggiore (the lake west of Lugano - LSZA and north of Malpensa - LIMC) is limited between FL95 and FL 195.

How do you explain these discrepancies?

Thanks and regards

Andrea
