I am an avid user of Foreflight when flying in the US and have been patiently waiting for somwone in Europe to provide a similar product. SD seems to provide similar VFR capabilities but are there any plans to provide at the very least, IFR GPS navigation?

Not quite.

In applications like Foreflight and WingX (mentioned above) you have the option of a number of different chart views.

In the case of Foreflight for example, you can view FAA Sectional (VFR) charts or FAA Low/High Airways charts. They are completely different charts and the IFR ones only provide information pertinent to IFR flight such as Airways, Navaid, Intersections, MEA, MRA, crossing altitudes and lots more without any terrain or ground features depicted. There is so much information on IFR charts, especially in Europe, it would probably be difficult to read with a VFR background unless you zoomed in until only a small area of airspace was displayed which is not ideal when ATC gives you a revised clearance over a large distance.

As mentioned earlier, some of this information may be in SD but I have not yet had chance to use it. However, if the information is not part of the chart data, then SD would be limited for use during IFR flight.

I guess I should download the trial and see what is there
