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outdated (offset) NDB/VOR approaches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“)

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

Motivation
The primary motivation for any
"Database controlled approach"
is
- enhanced flight safety
- economic benefits
- positive environmental impact

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

Problems of Database Integrity
RTCA DO-200A
"The end-user is responsible for the integrity of the
Section 1.4 - Application of Standard
data"
• 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)

Problems of Database Integrity
• 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

Problems of Database Integrity
• 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: simulator, aircraft, training handouts
Time: 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

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 integritychecks and data handling ---> Flightops

Time:

10.6. Database Integrity
10.6.1: Database has to be obtained by RTCA DO-200A certified
database supplier
10.6.2: If supplier not certified additional checks have to be carried
out through software or approved manual means (for all
procedures below MOCA) by the operator
10.6.4: Operators should consider additional checks even if
database is obtained by certified supplier

2. Additional Integritychecks ---> Softwaretool

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 referencedatabase, 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
- 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“
