So will ATC be allowed to have us fly groundspeeds then? Makes their life a lot easier when dealing with converging traffic as well... Because we couldn’t measure it "back then” but have the technology now.
We can perfectly fall out of the sky in the airmass providing the perfect requested track at a certain groundspeed... There is a difference between what we use and need to fly, and what we provide to the outside world. It's not because we have to comply with a track request, we have to change what we use on the flightdeck. We can perfectly fly HDG up and provide tracks on many aircraft. Tracks are dynamic influenced by the wind. But our primary point of reference is the air mass because that’s how our wings work.
What about hovering heli's? Their track indication is going to be all over the place close to zero airspeed. What in visual circuits? In track values all turns are going to be 90°. That should to be easy turning... right...?
