Just got this answer from Hannah at SD…
” No, the in-flight navigation tools in the PC software are quite rudimentary compared to the full mobile apps for iOS/Android, so the functionality is not quite as developed. It’s not possible to drag up the compass rose like you can on mobile, but it’s worth noting that you can switch to a separate Instrument View via the main navigation menu (see screenshot below), which gives you a full-screen view of the HSI.”

On a tablet or phone, you can swipe up the HSI instrument from the bottom so that the entire instrument becomes visible. Is there a way to do the same when using SD on a PC running Windows? In other words, to make the entire instrument visible?
