One question I have is this, what happened to the “filed” airspeed/Mach number listed on each flights main info page. One side would have what the airspeed was filed and under “Actual/Estimated” is the flghts current aispeed or MACH number.

Why in the “Scheduled” airspeed data missing now on most all flights?

Any help or insight into this would GREATLY be appreicated!
