AIXM 5 Implementation in Europe AIXM 3. 3

Why Digital NOTAM Dynamic/temporary data Static Data

Digital Aeronautical Data static + dynamic

Digital NOTAM can improve safety

Closed runway example L 05 R 05

Work on the runway ATIS PIB !? ! TWR

Work on the runway 56 feet

Developments/Projects that could prevent such events • On-board moving maps – airport layout – own ship position • Graphically displayed taxi route/clearance • Also needed – actual operational status of airport movement area elements – requires “digital NOTAM” © TUD

What is a “digital NOTAM” • Example - TWY closure – Today, published as NOTAM • • • A 0874/03 NOTAMN Q) EBBU/QMXLC/IV/M/A/000/999/5054 N 00429 E 005 A) EBBR <OK for computers> B) 0308250500 C) 0310271600 <not OK for computers> E) TAXIWAYS OUTER 7 AND E 6 CLSD • Digital NOTAM = Fully data modelled NOTAM – intended for computers – using the Aeronautical Information Exchange Model (AIXM) version 5

What is a “digital NOTAM” • Instead of • <text>TAXIWAYS OUTER 7 AND E 6 CLSD</text> • Use explicit feature properties – For example… • • <taxiway> <name>OUTER 7</name> <status>CLOSED</status> </taxiway> <name>E 6</name> <status>CLOSED</status> </taxiway> – This is a much more closer to a truly digital NOTAM • … and also the goal of AIXM 5

AMDB/x. NOTAM Study • • • Gap Analysis ED-99 A – AIXM and Prototype AIXM 5 schema Validation of AIXM temporal model (x. NOTAM) Validation of results in real scenario in flight simulator – Use AIXM 5 message to announce temporary change – Visualise change information on cockpit display “static” database Digital NOTAM Decoder

Procedure-x. NOTAM Study Objective: To demonstrate the technical possibilities of digital NOTAM for updating Terminal Procedure data in an onboard database From: 2007 -06 -01 T 12: 00 Z Until: 2007 -06 -22 T 23: 59: 00 Z Due to temporary obstacles, minimum altitude raised to 4500 ft between RID and DF 271.

Prototype Application • Procedure x. NOTAM Processor (Px. P) – Reads procedure data from DB including temporary changes – Features an UI to interact with the displays – Checks effectivity of procedure change • Displays – ND: plan view of approach channel – PFD: 3 D view of approach channel Procedure DB Px. P Navigation Display (ND) Primary Flight Display (PFD)

Scenario 1 Procedure transition temporarily unavailable due to temporary restricted airspace

Scenario 2 Segment leg minimum altitude raised

Scenario 3 Temporarily Restricted Area affects RNAV procedure; different fixes are used

2008: EUROCONTROL Digital NOTAM Trial

Objectives • x. NOTAM (digital NOTAM) Trial – 2007 – demonstrate the maturity of the “digital NOTAM” concept – validate the AIXM 5 timeslice model to managing permanent and temporary changes – check the completeness of (selected) AIXM 5 feature definitions – involve AIS Offices from ECAC State as test digital NOTAM data providers – identify potential digital NOTAM users and applications – identify essential bottlenecks that could prevent early adoption of digital NOTAM – to show that digital NOTAM can improve safety

Baseline (Static) Data • Providers and Users will not have to provide Baseline data • Initial data exported from the EAD Static Database (SDO) • Maintained by a constant feed of data from the SDO

x. NOTAM Provider Interface • Providing data = x. NOTAM Provider Interface • It shall run – In a Web browser – Through a secured Internet (https) connection

x. NOTAM Provider Interface • Workflow – From origination to publication – Start point is an already published NOTAM. The interface will not be used to create NOTAMs. It will encode them. – List of real-world NOTAM, that are "to be processed" – “Processed NOTAM" shall be "read-only" • Performance – Answering queries should be within 30 seconds

Getting Data • 4 ways to get data: – x. NOTAM User Interface – Subscription – Web Service (SOAP) – Web Feature Service (WFS)

Web Feature Service (WFS) • Enable the visualisation of the x. NOTAM database content with Sky. View 2

Scope • Events – closure or limited use of airport, runway, taxiway – activation of restricted airspace, ad-hoc restrictions, etc. – closure/opening of conditional routes – temporary obstacles • Geographical coverage – Europe … but may be extended if requested! • Duration – end January till end June 2008 … but may be extended if requested!
