Overview

• Introduction

• AIS to AIM

• Benefits of GIS

• eTOD Management

Introduction

1. What is my responsibility?

Providing Aeronautical Information Service (AIS) to users.

2. What is AIS ? is a service established for the provision of aeronautical information/data necessary for safety, regularity and efficiency of air navigation.

Introduction

Objective of AIS is to ensure the flow of information necessary for the safety, regularity and efficiency of international civil aviation.

Product centric provision of aeronautical information

Introduction AIS To AIM

Due to the challenges of providing Quality Data to the global Air Traffic Management (ATM) systems, AIS has transitioned to AIM.

Aeronautical Information Management (AIM) is data centric, in order to provide the “right information at the right place and the right time”.

Introduction

For AIM in Kenya to succeed, Geographic Information System (GIS) has provided the necessary functions which help in processing:

Aeronautical Information e.g

• Using AIXM -supports the data-centric environment

• Aeronautical Charts,

• Aeronautical Data Creation

• eAIP Management etc.

Benefits of GIS Reliable, Fast & Cost – effective in:

• Creating, visualizing, analyzing & disseminating aeronautical data.

• Updating charts to reduce latency, redundancy & errors.

• Production of wide range of ICAO- compliant charts.

• Sharing data using AIXM

eTOD

eTOD is electronic terrain obstacle data

Amendment 33 to Annex 15 (Aeronautical Information Services) established Chapter 10 (Electronic Terrain Obstacle & Data) and Appendix 8 Introducing as global standard requiring states to establish two databases, electronic Terrain database and one for navigation obstacles.

Electronic Terrain and Obstacle Data (eTOD)

• Obstacle: All fixed and mobile objects that are

located on an area intended for the surface movement of aircraft or that extend above a defined surface intended to protect aircraft in flight.

• Data is defined by four coverage areas around any aerodrome, and stored in a geodatabase with ICAO-defined attributes for the obstacle and terrain feature classes.

Terrain Definition

The surface of the Earth containing naturally occurring features such as mountains, hills, ridges, valleys, bodies of water, permanent ice and snow and excluding man-made obstacles

Terrain Definition

Terrain – Kisumu Airport

Why eTOD?

Increased Equipage of Aircraft and CNS/ATM Systems that are data - driven

General Aviation Requirements

Low cost applications available but certain danger in that these applications may be using unchecked data

Phases of Flight

Different terrain and obstacle data specification for various phases of flight

eTOD Coverage Areas

• Area 1: Entire State territory

• Area 2: Aerodrome terminal control area

• Area 3: Aerodrome/heliport area

• Area 4: Restricted to precision approach category II and III operations area (terrain only)

General Requirements for Data Acquisition

• Many methods acceptable for capturing aerodrome mapping data

Many methods are acceptable for capturing aerodrome mapping data • Subject to the requirements specified in Annex 15 ( AIS) and Doc 9881(Guidelines for Electronics, Terrain, Obstacle & Aerodrome Mapping Information)

-e.g: aerial photogrammetry, satellite photogrammetry, field surveying, and digitization of existing analog charts

• A description of the process used to acquire aerodrome mapping data must be provided.ubMany methods acceptable for capturing aerodrome mapping data
