[Milsurplus] Schedule "A," "B?"

[C Whitaker]

de WB2CPN
Don't know what the signs were for, but I know the
FAA or CAA used the word "Schedule" to give a
name to a construction program, or a new communications
system.  When I got into AF air traffic control  in
1946 the controller's key systems and communications
with control towers, airways stations, etc, were already
in place.  It may have been "Schedule F" because those
little brown loudspeaker boxes were called "Sked F Boxes".
They were around in USAF for years and years.
