Why are so many things abbreviated in NOTAMs and other similar documents?
Even words that aren't very long to begin with are often abbreviated,
saving
only a letter or two. I can't think of any situation today in which
bandwidth
would be so severely limited that saving a letter or two would make a
difference, so I assume there is some historical reason for the
abbreviations.
Were such messages transmitted by Morse code or something in the past, or
is
someone still transmitting them that way (or over some other extremely
slow
channel) today?



Org dsgnd for 110 Bd tty. ;-)



The TTY was 45.45 bits/s in US and 50 bit/s in Europe,
with 5 bit coding (Telex).

The 8 bit 110 bit/s thingy is newer.
