Even without a STAR or a runway, the box knows the elevation of the landing airport so will have a rough TOD point displayed
Well, this is exactly what I intended, and it took to me some time trying to convince development guy about this capability, but, withou success.
At the moment in the model I'm using, no TOD is calculated without at least a destination runway insertion.
Not a big deal, but it is a matter of principle
Thank you!
