Motivation
• GPS/FMS equipment with accuracies better then 0,3 nm is standard today • GPS/FMS-RNAV SIDs and STARs have positive impact in TMA-Ops in all aspects • GPS-NPAs are the primary NPA-procedures over outdated (offset) NDB/VOR approaches • Conventional Procedures are flown on regular basis with use of FMS/GPS („managed modes - VNAV“) Lufhansa German Airlines, Capt. J.Schadt

Motivation
• GPS is the system for ermerging airports with "problematic" infrastructure ---> CIS: see Samara - UWWW AFI: see Addis Abbeba • Operators experience every AIRAC - Cycle Nav database problems

Motivation
The primary motivation for any
"Database controlled approach"
is
- enhanced flight safety
- economic benefits - positive environmental impact Lufhansa German Airlines, Capt. J.Schadt

Definition: Database Integrity
EUROCONTROL
Database Integrity describes the probability for source data to be stored "correct" inside the FMC ---> after it ran through the process of final database generation.

Database quality management
EUROCONTROL 1. Plausibility checks Process owner: Database supplier 2. internal Integrity checks Process owner: Database supplier 3. Integrity checks during "packing" Process owner: FMC - Manufacturer 4. "Fly the database" Process owner: Medium: Airline Pilot report Future Goal

Problems of Database Integrity
EUROCONTROL RTCA DO-200A "The end-user is responsible for the integrity of the data"
Section 1.4 - Application of Standard • Navigational data are generated today and in short to medium future by unsecure/uncertified processes • no "usable" standards exists for generation of databases with guranteed integrity ---> RTCA DO-200A cannot be implemented today (even if JAA TGL-9 is regulating implementation) Lufhansa German Airlines, Capt. J.Schadt

Problems of Database Integrity
EUROCONTROL
• there will be no fully implementable procedures for database integrity available for the next years by any non airline organisation.
• Even a mandate will not change the situation due to non compliance Negative example: Implementation of WGS-84 Lufhansa German Airlines, Capt. J.Schadt

Problems of Database Integrity
EUROCONTROL
• there will be no fully implementable procedures for the implementation of GPS/FMS-RNAV procedures (or conventional procedures used with RNAV equipment), which depend on the availabilty of procedures to ensure database integrity
---> the use of RNAV - equipment is the business case of the future

Database Integrity for Operators
To ensure a high level of database integrity ---> GPS - NPA, GPS/FMS-RNAV - (+ Overlay -) procedures.
---> 5 level integrity concept ("multilayered system") 1. Training for all pilots Tool: Time: simulator, aircraft, training handouts permanent ---> all fleets 2. Check of NavDatabase prior effectivity to detect changes of “Ops - critical" data incl. an immediate reaction scheme Tool: DbIT ™ (Database Integrity Tool) ---> inservice 08/2000 Time: 2 - 5 days prior database effectivity Lufhansa German Airlines, Capt.

3. Check of "critical" data prior starting the procedure (e.g. GPS-approach) by the flightcrew Tool: Time: charts, crew operating procedures 10 - 15 minutes prior starting approach 4. Plausibilty check during approach Tool: Time: charts, crew ops. procs., training during approach 5. Administrative seperation of database integrity checks and data handling ---> Flightops Tool: Time: internal organisation permanent ---> all fleets Lufhansa German Airlines, Capt. J.Schadt

Implementing Database Integrity
EUROCONTROL 1. Flight Crew Procedures
---> Databaserequirement according TGL-3, I.6.2 (h)
2. Additional Integritychecks ---> Softwaretool
TGL-10, Section 10.6.2
... the operator must implement navigation database integrity checks using appropriate software tools or approved manual procedures to verify data relating to waypoints below the applicable minimum obstacle clearance altitude...

Goal Ensure database integrity in regard of “Ops critical" data prior database effectivity (applicable to RNAV and non RNAV procedures) Way Implementation and maintenance of a reference database, which will be run by flightops.
All changes in comparison to the referencedatabase will rated as "critical" or "non critical".
"Philosophy" Detected data changes of critical data will lead to immediate disauthorization of the applicable procedures.
Parallel the database supplier will be informed and required to present a solution.

Conclusion
- Operators are forced to act due to the increasing number of published RNAV + Overlay Procedures and insufficient database integrity processes
EUROCONTROL
- Operators even have to apply higher standards in respect of less experience with RNAV procedures and database integrity issues - Training in all respects for all involved personel is vital for the success of RNAV One incident or accident stops the whole „RNAV Movement“ Lufhansa German Airlines, Capt.
