into Flight procedure Design Environment

Vadim Tumarkin, LGS, Latvia

PBN Implementation and PANS-OPS provisions Workshop

Minsk, Republic of Belarus 7-10 April 2015

PBN/PANS-OPS Workshop, Minsk 2015 1

Riga FIR PBN based Airspace concept development and implementation


Presentation purposes

• Outline eTOD scope and benefits with focus on PBN;

• Remind eTOD needs for conventional and PBN Flight Procedure

Design;

• Review eTOD ICAO provisions;

• Share Latvian eTOD production and management experience;

• Consider current eTOD implementation difficulties dealing with FPD;

• Discuss CRM implementation issues using eTOD;

• Present eTOD implemented practices commonly elaborated by

eTOD provider, FPD SW developer and ANS provider.


Application of CRM for

conventional navigation


What we need to implement CRM


Application of CRM for PBN


This leads us to the following conclusion

• CRM is staying in the game for PBN procedures design;

• CRM has to be improved to have possibility to use eTOD as an input;

• CRM Obstacle data has to be added by CRM Terrain data taking into

account the ICAO eTOD provisions;

• The new solution is required to effectively upload eTOD into CRM

environment.

eTOD industry request example


Dear colleagues, We are interested in obtaining the electronic obstacle data and are kindly asking if you could provide us with sample files of both xml and ASCII format. That way we can determine whether we can read the data with our applications. Could you provide us with information on fees and frequency of updates of the obstacle data files? We read on your website that the access to eTOD data could be given to registered users. Our user name is AIMZRH. We would very much appreciate your response. Kind regards, Anna Gernss Aeronautical Information Management Lufthansa Systems FlightNav Inc. P.O. Box 202 8058 Zurich Airport Switzerland

Contour lines associated with vertical accuracy


DSM

DTM

DEM supported by AIXM 5.1

• In recent years, the point densities for DTM (DEM) have increased

dramatically due to the use of new sensors and digital processing

capabilities, and often reach 1 point per square metre.

• For this reason, DEM direct implementation for Flight procedure design

purpose becoming more and more problematic and the innovative

solution is needed to make the design process more effective.

• AIXM 5.1 has a possibility to form terrain data set for predefined areas as

specified in Annex 15, Chapter 10.

• AIXM 5.1 VerticalStructure feature may be used to store Terrain data set.


AIXM 5.1 VerticalStructure


• <feature> Vertical Structure consist of several <object> Vertical Structure part

• Obstacle Vertical Structure may be realized by the following Terrain geometry elements:

• Point

• Line

• Polyline

• This structure is applicable both for the complex obstacles and for Terrain also with an appropriate vertical Extent value associated with specific terrain parts.

Grid Terrain vs DEM contour lines


Latvian State area 1 terrain

representation through Grid

requests approximatelly 13 millions

points using AIXM 5.1 <feature>

Vertical Structure.

To reduce the storage volume

needed for Terrain presentation by

means of AIXM 5.1 it was decided to

implement the following mechanism:

Terrain data set represented as

DEM was divided for slices with a

vertical step that is an equivalent of

the half of the vertical accuracy for

area of the interest.

At the this step DEM is transformed

into contour lines associated with

vertical accuracy.

DEM presentation using AIXM 5.1 contour lines


Latvian METRUM Company has

prepared terrain digital model in form

of the AIXM 5.1 contour lines using

“VerticalStructure” feature.

Then, that AIXM 5.1 terrain snapshot

was successfully imported in LGS

integrated AIM DB by the Data

Manager tool provided by the R.I.S.K.

Company.

AIXM 5.1 terrain data stored in LGS

AIM DB were successfully retrieved

and processes during Flight

procedure design by the PANDA

system.

AIXM 5.1 DEM contour lines benefits

• DEM presentation using AIXM 5.1 contour lines provides the following benefits for automation of the Flight procedure design process keeping calculation accuracy:

– Generalize terrain data and significant reduce data volume and storage resources needed;

– Directly implement AIXM 5.1 DEM contour lines for Instrument approach procedures altitude and Minimum altitudes calculations within the obstacle assessment areas associated with the procedure constructed;

– Reduce terrain data processing to expedite Flight Procedure design process.
