Narrative:
Our approach clearance was: join the localizer, cleared for the visual, maintain visual separation from parallel traffic, and finally, maintain a specified airspeed. Problem being with all this is that the airspeed was faster than the traffic, which we passed on final. The FAA inspector on the jump seat was not impressed! This seems to me to be another example of a controller trying to fly an airplane which he/she has little idea of the capabilities and constraints that apply. Better ATC procedures are in order here at stl.

Title: FLC OF AN ACR LGT ACFT OVERTOOK THE TFC ON THE PARALLEL DUE TO THE SPD DIFFERENTIAL OF THE 2 ACFT.
Narrative: OUR APCH CLRNC WAS: JOIN THE LOC, CLRED FOR THE VISUAL, MAINTAIN VISUAL SEPARATION FROM PARALLEL TFC, AND FINALLY, MAINTAIN A SPECIFIED AIRSPD. PROB BEING WITH ALL THIS IS THAT THE AIRSPD WAS FASTER THAN THE TFC, WHICH WE PASSED ON FINAL. THE FAA INSPECTOR ON THE JUMP SEAT WAS NOT IMPRESSED! THIS SEEMS TO ME TO BE ANOTHER EXAMPLE OF A CTLR TRYING TO FLY AN AIRPLANE WHICH HE/SHE HAS LITTLE IDEA OF THE CAPABILITIES AND CONSTRAINTS THAT APPLY. BETTER ATC PROCS ARE IN ORDER HERE AT STL.
