The successful application of regulations concerning the safety and regularity of CNS/ATM systems
operation and the achievement of regulatory objectives depend on the appreciation by all individuals concerned of the
risks involved and on a detailed understanding of the regulations. This can be achieved only by properly planned and
maintained basic training, qualification training and recurrent training programmes for all persons involved. ATSEP play
a significant role in the safe operation of CNS/ATM systems, and international regulations require that they be
appropriately trained.
