The Customer Service System (CSS) of the BT Group (previously British Telecommunications) is the core operational support system for BT, bringing in 70% of income for the company (figures from 1997).

The Aeronautical Fixed Telecommunications Network (AFTN) is a worldwide system of aeronautical fixed circuits provided, as part of the Aeronautical Fixed Service, for the exchange of messages and/or digital data between aeronautical fixed stations having the same or compatible communications characteristics.
The BT.709 red and blue primaries are the same as the EBU Tech 3213 (PAL) primaries. The y G coordinate too is the same, while x G is halfway between EBU Tech 3213's x G and SMPTE C's x G. The resulting BT.709 color space is almost identical to that of the BT.601-6 used by PAL and NTSC, and covers 35.9% of it. [19]
16-line message format, or Basic Message Format, is the standard military radiogram format (in NATO allied nations) for the manner in which a paper message form is transcribed through voice, Morse code, or TTY transmission formats.

The GRIB format superseded the earlier ADF format in 1998–99. The ADF format used 300-nautical-mile (560 km) intervals; this interval was large enough to miss some storms completely, so calculations using ADF-predicted weather were often not as accurate as those that can be produced using GRIB-predicted weather. Routes and flight levels
Multiplan floppy disk for Macintosh. Multiplan is a spreadsheet program developed by Microsoft and introduced in 1982 as a competitor to VisiCalc.. Multiplan was released first for computers running CP/M; it was developed using a Microsoft proprietary p-code C compiler [1] as part of a portability strategy that facilitated ports to systems such as MS-DOS, Xenix, Commodore 64 and 128, TI-99/4A ...
PFD with key instrument displays labelled PFD of a Garmin G1000. The details of the display layout on a primary flight display can vary enormously, depending on the aircraft, the aircraft's manufacturer, the specific model of PFD, certain settings chosen by the pilot, and various internal options that are selected by the aircraft's owner (i.e., an airline, in the case of a large airliner).
A BT.656 data stream is a sequence of 8-bit or 10-bit words, transmitted at a rate of 27 Mword/s. Horizontal scan lines of video pixel data are delimited in the stream by 4-byte long SAV (Start of Active Video) and EAV (End of Active Video) code sequences. SAV codes also contain status bits indicating line position in a video field or frame.
