6.4	ICAO's TRAINAIR Programme

CNS/ATM TECHNOLOGIES FOR ATC

(Presented by Latvia)

Information Paper

1.	Introduction

1.2	In the frame of ICAO Trainair Program ANS Training Centre (Riga, Latvia) developed a new training course for senior ATC personnel to prepare these personnel for the phase in of new systems and procedures based on the CNS/ATM concepts.

2.	Training Goal

2.1	To provide senior ATC personnel with an understanding of developments in communications, surveillance and satellite based navigation and their impact on air traffic management. The training is intended to prepare these personnel for the gradual phase in of new systems and to enable them to make informed recommendations to their civil aviation administrations regarding ATC requirements.

3.	Course Description

3.1	This training course will focus on the technologies which enable the implementation of CNS/ATM and examine the impact of those technologies on the Air Traffic Control environment. During the training participants will compare the new technologies with currently used technologies for a given airspace through a series of lectures and group discussions. Using simulated exercises participants will examine the impact of implementing CNS on ATC and ATM and make recommendations regarding operating procedures and the resources required for full implementation.

4.	Mode of Delivery

4.1	The training is planned as group training course including some individual training by means of simulators (depends on the existing skills of the proposed participants).

5.	Languages of Instruction

English, Russian

6.	Other Possibilities

6.1	Using the TRAINAIR course development methodology and modular design it is possible to update training materials as required to reflect actual implementation of systems and operational standards and recommended practices .
