Fields "B" and "C" are in the format YYMMDDhhmm, with times given in Universal Co-ordinated Time, also known as UTC or Zulu time. Sometimes a "D" line may be present. This gives a miscellaneous diurnal time for the NOTAM if the hours of effect are less than 24 hours a day, e.g., parachute dropping exercises tend to occur for short periods of a ...
NOTAM Code is an aeronautical radiotelegraph and radiotelephony brevity code used to transmit information about radio navigation aids, airports, lighting facilities, dangers to aircraft, and actions related to search and rescue. All NOTAM Codes start with the letter Q, to distinguish them from radio call signs, and always consist of five ...

AIXM 5.0 aligned the format with current ISO standards for geospatial information, including GML, allowed for modular development and future extension and was also the first version to enable digital NOTAM. This version is still in use by some “early adopters” including the FAA.
A Digital NOTAM (DIGITAM), is a data set made available through digital services containing information concerning the establishment, condition or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which is essential to systems and automated equipment used by personnel concerned with flight operations.
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.
In meteorology and aviation, terminal aerodrome forecast (TAF) is a format for reporting weather forecast information, [1] particularly as it relates to aviation. TAFs complement and use similar encoding to METAR reports. They are produced by a human forecaster based on the ground.
METAR is a format for reporting weather information. A METAR weather report is predominantly used by aircraft pilots, and by meteorologists, who use aggregated METAR information to assist in weather forecasting. Raw METAR is the most common format in the world for the transmission of observational weather data.
