And face it, in the F-4 one rarely looked at actual analog airspeed anyway after configured for landing (overhead or straight-in), you verified and just listened to the comforting steady AOA tone.
Airspeed was primary, aoa secondary information. The Aoa tone was not good for comunicating a trend, not each unit had its individual tone. The tone changed when going from fast to onspeed, from onspeed to slow in stepped and not fluid way.
Your comment concerning monitoring exact speeds with those digital indications my flights in the cockpit of A320 gave another impression. The crew dialed the speed into the respective window and the automation was doing the work, same like the Asiana crew was doing.
I know it should be different and should be closely monitored, but I have my doubts. If you would asked the average pilot out of the blue what his indicated airspeed would be, he would read you the numbers he dialed in before?
