Okay call me daft but where in the nav panel can I see if there are geological or biological sites.
I'm in a system with at least one planet with geological sites but I have no clue where to see that mentioned in the nav panel.
I'm going to assume he means the system map information panel not the nav panel in the cockpit. Any landable world with volcanic activity is going to have Geo sites. Trouble is that if it also has biological you won't know unless you wait for it in the FSS. No other way to tell as far as I can see.
