1. Seminar on electronic terrain and obstacle data (Peru, Lima, 6-10 November 2017)
Participant Suriname:
SHARITA RADJIE, AIS OFFICER
NATASIA HOMOET, AIS OFFICER
SHAKTI GOERDAT, ATC/ AGA

2. eTOD is a follow up of PBN. And what is PBN
eTOD is a follow up of PBN. And what is PBN? PBN stands for performance based navigation, this is a modern navigation system in the aircraft, on the ground and in the air (f.e. sattelite). With PBN it is possible to create more routes. And to create more routes eTOD has been implemented. eTOD stands for electronic terrain and obstacle data. Obstacles are fixed (whether temporary or permanent) and mobile objects, or parts thereof. Terrain is the surface of the earth containing naturally occuring features such as mountains etc., excluding obstacles.

4. eTOD had to be implemented on the 12th of November 2015
eTOD had to be implemented on the 12th of November But not all the countries had there information in place, so they did not achieve the deathline. There is a need for eTOD because of the growing numbers of obstacles around airports and there is a contributing demand for accurate and up to date terrain and obstacle data. That’s why this seminar was necessary.

6. eTOD has 4 area’s: Area 1: the entire territory of a State
eTOD has 4 area’s: Area 1: the entire territory of a State. Area 2: within the vicinity of an aerodrome, subdivided as follows: Area 2a: a rectangular area around a runway that comprises the runway strip plus any clearway that exists; Area 2b: an area extending from the ends of Area 2a in the direction of departure, with a length of 10 km and a splay of 15 per cent to each side; Area 2c: an area extending outside Area 2a and Area 2b at a distance of not more than 10 km from the boundary of Area 2a; and Area 2d: an area outside the Areas 2a, 2b and 2c up to a distance of 45 km from the aerodrome reference point, or to an existing terminal control area (TMA) boundary, whichever is nearest;

7. Area 3: the area bordering an aerodrome movement area that extends horizontally from the edge of a runway to 90 m from the runway centre line and 50 m from the edge of all other parts of the aerodrome movement area; Area 4: The area extending 900 m prior to the runway threshold and 60 m each side of the extended runway centre line in the direction of the approach on a precision approach runway, Category II or III.

9. The seminar was about area 2
The seminar was about area 2. This area is from the aerodrome reference point with a radius of 45 km. The radius can be smaller, this depends on every State according to there traffic and geographical points. How do we collect the data for this area? The GIS was mentioned, this stands for Geographic Information System. This system is not 100% accurate, so the LIDAR (Light Detection and Ranging) is also used to get more accurate geographical points. A few countries also use drones.

10. When the data for eTOD is collected, it will be managed in a database
When the data for eTOD is collected, it will be managed in a database. This will also be the database for the eAIP, including electronic Notam, AIC, PIB etc. The database will also cover the AIXM (Aeronautical Information Exchange Model). Identifying the coverage areas and storing the data with the specified requirements have posed major challenges to the aviation community. ICAO member states are struggling to find a solution for managing this large collection of inherently spatial data in the most reliable and cost efficient way. NG Aviation meets these challenges.

11. NG Aviation from Czech Republic who also participated in this seminar, is a service provider who is able to meet the need of any contracting state. They specialize in aeronautical databases. They have the whole package, which includes all the information needed to set up our database for eTOD. To upgrade to AIXM they work with the most modern technology. The package includes: training personnel, set up of the unit, upgrading of the AIXM if needed etc. The program of NG Aviation offers the possibility for aeronautical users to get access to aeronautical data. Safety features are included. NG Aviation uses the latest version of AIXM

12. We are now in the state of transition from AIS to AIM
We are now in the state of transition from AIS to AIM. The biggest change in the transition to AIM will be increased use of the computer technology in the management of information, with an increased emphasis on the digital form of data that will drive all processes for the management of information. The terrain and obstacles are compilation and provisions and they are also parts of the data sets of the integral part of the transition to AIM. According to Annex 15 the AIS needs to have the latest information about aviation which includes every information about eTOD so that the AIS can increase safety. Reffering to the above states are highly recommended to establish a special unit within the AIS to set up, manage and maintain eTOD. States were also encourage to train AIS personnel in ICT to manage the AIM databases, and timely flow of aeronautical data and aeronautical information.

13. CONCLUSIONS: Ref. Annex 15, it is mandatory to integrate from AIS to AIM. All data must be up to date and validated every year. All data regarding obstacles and terrain must be validated every 5 years. It is mandatory that contracting states do there part to digitalize the data. With respect to eTOD Suriname has one big advantage, because the two most important airports, SMJP + SMZO, are on flat terrain and there is not much obstacles and mountains/ hills. Topographic and Geographic data is necessary for eTOD collection. To accomplish this human resources must be in place. This must be a cooperation between AIS, AGA and Geodetic personnel. The best software program is the AIXM in combination with AIME. Price tag approx. $ 1million. The AMHS system will need to be replaced in a time frame of 3 to 5 years. In South America the countries, Argentina, Uruguay, Paraguay and Brazil are making progress. In Mid America the countries, Panama and Mexico are the leading states in eTOD. NG Aviation has a whole presentation about there system and are willing to come to Suriname. We can organize a telephone conference via skype.

14. PLAN OF ACTION
The human resources need to be in place. Jobs need to be created and also the salary aspect needs to be taken in consideration.
ISO training ( ISO 9001) needed to make the transformation from AIS to AIM, including IT training.
Standard Operating Procedures need to be created.
Legislation and Regulations need to be updated.
