Not sure about Avplan but I’ve noticed OZRunways are showing the speed in their latest version when using ADSB-in which is quite handy.
I tell you what, if you don’t have a Skyecho or compatible adsb-in for your EFB, you really are missing out. So many aircraft on there that you never know were right near you! I see aircraft, their altitude and speed, long before I hear any radio calls.
