Hello to everybody,
I am an ultralight pilot, based in the noth of Italy,
I am using SD to plan and monitoring my flights (using iPad3 as secondary GPS) .
Really great and professional product!!! There is no competitor at the same level.

I found some errors concerning radio frequencies:

Valeggio microlight sites frequency is 130.10 instead 130.00
Caorle airfield frequency is 118.125 instead 130.00

I will keep this topic updated when more errors will be discovered.
Best regards

Attilio
