NOTAM are safety critical Digital AIM Training - Digital NOTAM NOTAM are safety critical NOTAM can contain very safety critical information. Here are two examples.

Therefore it is essential that the users get the data. Missing this data might be the difference between a safe journey and a disaster.

Digital AIM Training - Digital NOTAM NOTAM numbers PIB A problem is the significant and constant increase in the amount of NOTAM issued world-wide in the last years. On average, 20 000 NOTAM are in force are every moment around the World. The system is becoming more complex and more dynamic. This is reflected in increased Pre-Flight Information Bulletins (PIB) that are suffering more and more of information overload. Who is affected: Airspace users Service Providers AIS/NOTAM offices Airports and other data originators Notes: Source: European AIS Database (EAD) EUROCONTROL Copyright 2011

NOTAM also have quality problems Digital AIM Training - Digital NOTAM NOTAM also have quality problems … irrelevant information … obstacles with imprecise positions … runway shortenings when the NOTAM simply gives a new TORA and does not really say WHERE the runway have been shorter (in what end) 10% of the NOTAM have errors according to a study done by the EAD on randomly selected messages! … complex restricted area boundaries that take hours to put on a map! Notes: … very long and complex to read!!! … typing errors EUROCONTROL Copyright 2011

Digital AIM Training - Digital NOTAM Pilot’s Perspective “Last line of defense” for safety Typically have less time to review NOTAMs than other customers NOTAM data not filtered or prioritized Digitize NOTAM data A study conducted by the American Institute for Research in the United States looked at issues facing pilots as they use the NOTAM system. Pilots are the last line of defense and must make safety decisions that could personally affect the pilot. As a consequence good NOTAM information is critical to pilots. Yet, pilots generally have the least amount of time to review the NOTAM information. Other customers like dispatchers and flight services have more time to review and consider the NOTAM information. Pilot challenges are compounded because the NOTAM information is not filtered or prioritized. A typical flights of 150 KM in the US can have a 40 page briefing containing hundreds of NOTAMS. A review shows that only a fraction of these NOTAMS have immediate consequence to the pilot. As a result, pilots are encouraging digital NOTAM as a way to better manage and communicate NOTAM information to pilots. Notes: EUROCONTROL Copyright 2011

What is a “digital NOTAM” Digital AIM Training - Digital NOTAM What is a “digital NOTAM” Instead of <text>TAXIWAYS OUTER 7 AND E6 CLSD</text> Use explicit feature properties For example… <taxiway> <name>OUTER 7</name> <status>CLOSED</status> </taxiway> <name>E6</name> In a digital NOTAM, the current NOTAM fields do no longer exist. Instead, the information is structured using the Extensible Markup Language (XML), according to a pre-defined schema. Every feature, every property and every possible situation needs to be identified by specific codes. Notes: EUROCONTROL Copyright 2011

Benefits – improved data quality Digital AIM Training - Digital NOTAM Benefits – improved data quality Digital data: clearer / more precise than free text enables validation automatic by the system visually by the operator Let’s now look at some benefits that Digital NOTAM will bring. Digital data is much more clear/precise than free text: Position of obstacles Shape of restricted airspace Schedules Etc. Therefore, digital data enables much more automatic validation checks: For example, if THR is displaced, check if declared distances and OCA/OCH have been modified, etc. Or, check the shape and location of a temporary restricted area Check the shape and location of the airport surfaces that are work in progress or temporarily closed Notes: EUROCONTROL Copyright 2011

Benefits – improved PIB Digital AIM Training - Digital NOTAM Benefits – improved PIB One radical improvement that is enabled by digital NOTAM is in the area of pre-flight information bulletins. - prioritise information by criticality - organise information by item concerned (runway, gate, etc.) - far better filtering capabilities - filter out irrelevant information, which can represent more than 50% of the current bulletins; - reduce the risk of information overload, which is a growing problem because of the significant increase in the number of NOTAM in force world-wide; - embed graphics where appropriate or even do a full graphical PIB The ultimate goal is a fully graphical, continuous briefing process from the flight planning phase, followed by pre-flight briefing, in-flight updates and post-flight de-briefing. The same information package would be available on the ground and in the air, continuously updated. This will also support the development of new, fully digital services for aeronautical information updates on board the aircraft, in graphical format.

Benefits – airspace activity maps for VFR Digital AIM Training - Digital NOTAM Benefits – airspace activity maps for VFR VFR flyers could also benefit from products enabled by Digital NOTAM. Make digital airspace reservation data available for VFR community -> enable graphical visualisation Currently, such applications either display the airspace as a circle based on the Q line or require human intervention for decoding the NOTAM text when the algorithms that try to extract the lat/long positions from the item E do not work, because someone has put a dot instead of a comma in the series of lat / long values.

Supported by AIXM version 5.1 Digital AIM Training - Digital NOTAM Supported by AIXM version 5.1 XSD UML Temporality Concept From a previous presentation, you have seen that AIXM 5 supports the implementation of the digital NOTAM concept. The main difference between AIXM 4.5 and AIXM 5.1 is the introduction of: A temporality concept Feature properties that are necessary to model conditions that are announced by NOTAM; typically, this means ‘operational status’ attributes and associated schedules. These are two essential pre-requisites for Digital NOTAM encoding. The challenge for AIXM version 5 is to model all these features and situations, knowing that the potential scope of NOTAM information is very wide. Notes: EUROCONTROL Copyright 2011
