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? -- Transpose mxsmanic and gmail to reach me by e-mail. |

Teletype machines and abreviations understandable by everyone without regard to native language. Teletype machines are still used in many parts of the world. -- Jim Pennino Remove .spam.sux to reply. |

My first "laptop" was a portable hardcopy terminal whose standard speed was 110 baud. High speed was 300 baud! Acoustic coupler for connectivity and rolls of thermal paper for media. It rocked. |

I was told that the fewer characters transmitted, the more cost-effective it became. I was hoping that in this age of the internet, they would change this before I had to take my written (no luck). I passed it anyway, but I'm certain that part of the questions I got wrong were for the stupid weather reading. |
