1. AIXM 5 Terminal Procedure Model Study “Verification of the AIXM 5 Procedures Model through cockpit simulation applications“

2. Objectives Investigation and Verification –Gap analysis procedure model – real-world data –Examination of AIP procedure data and NOTAM Implementation –AIXM relational procedure DB from UML model –Basic AIXM feeder interface Demonstration –Approach channel visualization in cockpit display –Visualize (temporary) changes (received in digital NOTAMs) (A0711/06 NOTAMN Q) EYVL/QPICH/I /NBO/A /000/999/5438N02517E010 A) EYVI B) 0612210001 C) PERM E) 1. INSTRUMENT APPROACH PROCEDURE RWY 02 CHANGED AS FLW: - MNM ALT CHANGED TO 3500 FT INSTEAD OF 3000 FT, - FAP/FAF ALT(HGT) CHANGED TO 2500(1906) FT INSTEAD OF 2200(1606) FT. 2. INSTRUMENT APPROACH PROCEDURE RWY 20 CHANGED AS FLW: - MNM ALT CHANGED TO 3500 FT INSTEAD OF 3000 FT, - FAP/FAF ALT(HGT) CHANGED TO 2500(1854) FT INSTEAD OF 2200(1554) FT. REF AIP EYVI AD 2.4-37/42.)

3. Procedures in European AIPs Primary focus: non-graphical IAP information –Tabular/textual description of procedures Examined the (e)AIPs of –Armenia, Denmark, Estonia, France, Germany, Hungary, Italy, Lithunia, Moldova, Netherlands, Slovenia Only Netherlands publishes detailed description of legs (ARINC style) of some RNAV procedures

4. Applying the Procedure Model … TF 116 MT TO 3.5 2000 ALT LA

5. Procedure NOTAM Analysis NOTAM set from EAD with NSC “P???” –Date Oct 20 2006, total number = 6731 Most NOTAM (appr. 80%) simply change status –“…PROC NOT AVLB… EXPECT RADAR VECTOR…” –“…PROC CHANGED. REF AIP…” Procedure NOTAM with “real” changes –OCA/OCH –Segment/Leg altitudes –Minima –Wrong NSC! Very few with more complex content: (A0711/06 NOTAMN Q) EYVL/QPICH/I /NBO/A /000/999/5438N02517E010 A) EYVI B) 0612210001 C) PERM E) ILS AND NDB (GPS) APCH RWY 10 FROM ROBEL INT CHANGED AS FLW: LEAVE ROBEL AT 6000. WHEN CROSSING R274 ERF/ BRG 091DEG ERT (WP DE014) TURN RIGHT TO FINAL DESCENDING TO 5000. REST REMAINS UNCHANGED.)

6. Procedure Data Availability AIS procedure data is hard to find –Rarely any procedure data published in other form than charts –Rarely any NOTAM with “real” changes to procedures Why? No generic procedure model available NOTAM free text form inappropriate for redefining a procedure DUE VOR/DME SPL NOT AVBL, INSTR APCH PROC AND COM FAILURE PROC ALL RWY CHANGED: USE VOR/DME AMS INSTEAD OF VOR/DME SPL. COM FAILURE PROC RWY 09, 18R, 22 AND 36C: SUBSTITUTE FIXES ON OUTBOUND TRACKS BASED ON VOR/DME SPL BY FIXES BASED ON VOR/DME AMS WITH SAME BEARING AND DISTANCE. MISSED APCH PROC RWY 18R: AMEND DO NOT OVERSHOOT SPL 240 TO READ DO NOT OVERSHOOT AMS 240. CONTINUE MISSED APCH ON RDL AMS 280. MISSED APCH PROC RWY 36R: AMEND EH637 2.8 SPL TO READ EH637 3.8 AMS. MAINTAIN 1500FT, WHEN PASSING EH637 CLIMB TO 2000FT. MISSED APCH PROC RWY 18C: AMEND EH638 5.3 SPL TO READ EH638 5.4 AMS. MAINTAIN 1500FT, WHEN PASSING EH638 CLIMB TO 2000FT.

7. Scenario – Temporary Restricted Airspace affects RNAV approach Frankfurt/Main (EDDF): RNAV (GPS) RWY 07L

8. AIXM Database and Display Application: Architecture AIXM Procedure DB MINIMUM ALTITUDE FROM LANUM ON R315 KLF TO 48.0 DME KLF TO READ 5000 Procedure data (internal format) AIXM XML messages (digital NOTAM and others) PxP* Pilot Procedure Selection Proc Data Extraction xNOTAM Functionality AIXM Processor Process AIXM files Integrate into DB AIP Procedure Data *Procedure xNOTAM Processor

9. Database Architecture and User Interaction Database stores baseline and delta data Baseline DB initially loaded with procedure data (from AIP) Decoded digital NOTAMs are written to Delta DB Choice between primary and temporary view Delta Baseline digital NOTAM Database

10. Implementation of AIXM Procedure DB Step 1: Strip down AIXM5 CM to necessary elements (classes, attributes, associations) Step 2: Derive relational model from UML class model –Manual process, automatic processing with Rose Data Modeler did not yield satisfying results Step 3: Implement relational model in DBMS –Choice was PostgreSQL due to its good spatial support –Manual creation of tables, attributes, keys

11. Status / Next Steps Implementing AIXM database and software –AIXM Processor –PxP –Display application digital NOTAM extensions May 2007: Final Demonstration Outcomes –AIXM Procedure Database implementation documentation –Procedure model investigation/verification report –Recommendations to improve AIXM support for Procedure NOTAMs –Cockpit simulation demonstration movie
