A BIT ABOUT NOTAM

NOTAM, "NOtice To AirMen", are notices containing essential flight operation information not known sufficiently in advance to publicize by other means. Just like weather reports, they include endless abbrieviated text (known as a contraction) which are sometimes difficult to figure out. 

Example:

Types of NOTAM's include the following: 

•          NOTAM(D): Information that requires wide dissemination and pertains to enroute navigational aids, civil public use landing areas listed in the Airports Facility Directory and aeronautical data related to IFR operations. 
•          NOTAM(L): Information that requires local dissemination, but does not qualify as NOTAM(D) information. This includes, but is not limited to, aircraft jettisoning fuel, bird activity, moored balloons, military training activity, etc.This type of NOTAM no longer exists, now part of "D" NOTAMs and distributed nationwide.
•          FDC: Information that is regulatory in nature pertaining to flight including, but not limited to, changes to charts, procedures, and airspace usage. It includes TFRs
