Digital NOTAM
March 2008 - AIXM
Why Digital NOTAMs?
– Everyone here knows the current Airport NOTAM situation
• NOTAMs submitted via phone to Flight Services• Flight Services creates NOTAMS• Almost always correctly interpreted over the phone• NOTAMS in Free-Form Text Format• Read like Telegrams• Corporations have third-party software to translate them
into something useful

Digital NOTAM Objectives
– Improve the Quality of the NOTAM• Mature Data Models follow standard formats
– Runway NOTAMs will ALWAYS look the same now• One creator means no mistranslations, however remote
– Improve the NOTAM speed from creation to distribution• User creates quality NOTAM using Data Model• Instant NOTAM activation means NOTAMs for temporary issues
like runway icing– Provide better NOTAMs for users
• Mature Data Models can be translated into– AIXM– ICAO– Proprietary airline software– Vector Maps
• Mature Data Models mean users can filter and sort on their requirements

NOTAM Formats• ICAO• Free-Form Text / FAA Traditional• Graphical Maps (later phase)
• Examples– USNS
• RWY 4L/22R CLSD WEF 0803012230-0803101400
– ICAO:• Q) QMRLC• B) 0803012230• C) 0803101400• E) RWY 4L/22R CLOSED
– Plain Language:• Runway: 4L/22R• Operating Status: Closed for all operations

Digital NOTAM Submission
– Website Interface• Originators (Airport staff) log into Digital NOTAM using
secure password• They select the airport(s) they have access to and view all
the current, active NOTAMs for that airport• They create an Event using an AIXM-compliant message• Also edit, activate and delete Events and NOTAMs• After activation, the NOTAM can be viewed by the aviation
users• Can view canceled and expired NOTAMs via a filtered
report

Using the Digital NOTAM System
– Website Interface• Public chooses airport• They select an airport and view all the current, active
NOTAMs for that airport• They select the format to view the NOTAM (AIXM, ICAO,
etc)
– System Interface• Third-Party software connects to Digital NOTAM Web
Service• Software selects NOTAM and inserts it into their system

Digital NOTAM System Architecture
– Digital NOTAM software hosted on FAA Servers.– Airport staff have secure accounts– SOAP/XML connection to external processes– Activated NOTAMS publicly available

Digital NOTAM: Next Steps
– Spring 2008• Develop application business logic• Integrate with external systems
– Summer 2008• Launch and Test prototype at trial airports• Validate application• Analyze existing NOTAMs to create fully-digital NOTAM
templates
– FY09• Continue to enhance and deploy capability.
