Dissemination of Airmen’s Information
The system for disseminating aeronautical information is made up of two subsystems:
o
The Aeronautical Information System (AIS), consists of charts and publications.
o
The NOTAM system is a telecommunication system.
Subsystems
o
AIS
Charts and Publications
o
NOTAM System
Telecommunications System
Airmen’s information is disseminated by the following methods: Aeronautical Charts
Flight information Publication in book form.
o
Methods
Aeronautical Charts
Instrument Flight Rules (IFR) o
En Route High Altitude Charts
o
En Route Low Altitude Charts
Visual Flight Rules (VFR)
o
Sectional Aeronautical Charts (SCAs)
o
Terminal Area Charts (TACs)
U.S. Terminal Procedures Publication (TPP)
o
Departure Procedures Publication (DP)
o
Standard Terminal Procedures (STAR)
o
Standards Instrument Approach Procedures (SIAPs)
Flight Information Publications
Chart supplements
National Flight Data Center (NFDC)
The National Flight Data Center (NFDC) is located in Washington, D.C. The NFDC was established by the FAA to operate a central aeronautical information service for the collection, validation, and dissemination of aeronautical data that supports the government, industry, and the aviation community.
Originators of airmen’s information are expected to inform the NFD in sufficient time before the effective dates of changes to permit publishing of aeronautical data on the various charts or in the appropriate publications.

What are the two subsystems for disseminating aeronautical information?
AIS and NOTAM System
Notice to Air Missions
A NOTAM is a notice containing information (not knowing sufficiently in advance to publicize by other means) concerning the establishment, condition, or change in any component (facility, service, or procedure of, or hazard in the NAS), the timely knowledge of which is essential to personnel concerned with flight operations.
Notice to Air Missions
o
All air traffic employees, regarding of the position, must immediately report any situation or condition considered hazardous to flight to an air traffic facility for appropriate action.
All Traffic Personnel Responsibilities
Air traffic personnel must accept all airmen information regardless of source or subject matter, provided the occurrence is no more than 3 days in the future. o
Obtain the name, title (if appropriate), address, and telephone furnishing the information and forward all the data to the appropriate Flight Service Station (FSS) for NOTAM issuance.
FSSs, Terminals, and Air Route Traffic Control Centers (ARTCCs) accept and disseminate NOTAMs.
Technical Operations Services (Tech Ops) Responsibilities
Technical Operations Services, Operation Center manager, or representative, is responsible for: o
Originating and canceling NOTAM information for shutdown, resoration, or any condition that affects the operations of navigational aids (NAVAIDs), frequenceies, or other electronic aids that affect safety of flight.
Known or reported malfunctions of a NAVAID must be reported to Technical Operations or Approriate personnel.
Information concerning maintenance shutdown of NAVAIDs, that are part of the NAS must be handled as follow:
o
Routine maintenace shutdown
– when possible, approval should be obtained sufficiently in advance of the proposed shutdown time to allow dissemination of a
NOTAM at least 5 hours before a shutdown will occur (see note)
o
Emergency shutdown
– when possible, obtain at least 1 hour advance, noticed so
that appropriate dissemination of a NOTAM at least 1 hour advance notices so that appropriate dissemination may be made before shutdown. o
Extended maintenance shutdown – notify the NFDC sufficeintly in advance to permit publication of the information prior to the shutdown date.
NOTE
: Approval is obtained from the ATC facility affected by the maintance shutdown.
Airport Management Responsibilites
Airport management is responsible for observing and reporting the condition of the aerodrome services, facilities, and movements area.
o
The FSS air traffic managers (ATMs) must coordinate with appropriate airport managers to obtain a list of airport employees who are authorized to orginate NOTAMs
Only airport management can close any portion of an airport.
Authority
The United States NOTAM Office (USNOF) is the authority ensuring NOTAM formats and is charged with monitoring the NOTMA System (NS)
All NOTAMs will be processed, stored, and distributed by the NS
The USNOF may edit any NOTAM (except FDC NOTAMs); the contents of a NOTAM must not be changes without notifying the originating facility
NOTAMs must have one of the following keywords as part of the tesxt, a keyworkd is used to make it easier to sort and locate the specific data needed.
o
RWY – Runway o
TWY – Taxiway o
APRON – Apron o
AD – Aerodrome o
OBST – Obstructions o
NAV – Navigation o
COM – Communcations o
SVC – Services o
AIRSPACE -- Airspace
o
ODP – Obstacele Departure Procedure
o
SID – Standard Instrument Departure
o
STAR – Standard Terminal Arrival
o
CHART – Chart o
DATA – Data o
IAP – Instrument Approach Procedure
o
VFR – Visual Flight Procedure
o
ROUTE – Route o
SPECIAL – Special
o
SECURITY – Security Unverified NOTAMs
Unverified aeronatucial information is used when authorized by Letters of Agreement (LOAs). An unverified NOTAM will have a (U) in it. A movement area or other information received that meets NOTAM criteria but has not been confirmed by the airport manger or designee would be unverified.

Which subsystem is used for dissemination aeronautical information?
The AIS

Ceritifed Source
Who is responsible for reporting a condition considerd hazardous to flight?
All air traffic personnel
NOTAM Classificaton
NOTAMs are classified into the following groups
o
NOTAM D
o
A NOTAM (D) is a classification of NOTAMs containing information concerning the establishment, condition, or changed in any aeronatutical facility, en route navigational aids, serices, procedures, hazards and civil public – used airports listed in the Chart Supplement.
NOTAM Ds are issued when the information requires wide dissmination via telecommuncation and pertains to en route NAVAIDs, civil public-use airports listed in the chart supplement facilities, services, and procedures.
Notice distributed by means of telecommunications, containing information concerning the establishment, condtiion, or change in any aeronautical facility, service, procedure, or hazard, the timely knowledge of which is essential to personnel concerned with flight operations.
o
FDC NOTAM
o
The classification of NOTAMs containing flight information that is normally regulatory in nature including, but not limited to, changed to IFR charts, procedures, and airsapce usage.
FDC NOTAMs are issued for:
Interim IFR flight procedures
o
Air traffic service route changes
o
Instrument flight procedure changes
o
Airspace changes in general
Temporary flight restrictions
o
Disaster/hazard areas
o
Aerial demonstrations
o
Hijacking
Flight restrictions in the proximity of the President and other parties
The NOTAM issuing authority is responsible for cancelling FDC NOTAMs
An FDC NOTAM must be issued to cancel and FDC NOTAM
o
Pointer NOTAM
Pointer NOTAMs are NOTAM D issued to point to additional aeronautical
information. The keyword in the pointer NOTAM must mathc the keyword in the original NOTAM
Pointer NOTAMs are issued by a flight service station to highlight or point out another NOTAM; such as an FDC or Parachute Jump Exercise (PJE) NOTAM
o
This type of NOTAM will assist users in cross-referencing important inforamtion that may NOT be found under and airport or NAVAID identifier
o
Keyword in pointer NOTAMs must match the keyword in the NOTAM D that is being pointed out
o
Keyowrds in pointer NOTAMs related to temporary flight restrictions (TFR) must be AIRSPACE.
o
FICON NOTAM
FICON NOTAMs are used to report the surface conditions on runways, taxiways, and aprons.
they are also used to report surface conditions of a helipad
