Part ATM/ANS.OR - ANNEX III - Common Requirements for Service Providers

MONITORING OF INTRODUCED CHANGES
(a) Monitoring is intended to maintain confidence in the safety support argument during
operation of the changed functional system. Monitoring is, therefore, only applicable
following the entry into service of the change.
(b) Monitoring is likely to be of internal parameters of the functional system that provide a
good indication of the performance of the service. These parameters may not be directly
observable at the service level, i.e. at the interface of the service with the operational
environment. For example, where a function is provided by multiple redundant resources,
the availability of the function will be so high that monitoring it may not be useful. However,
monitoring the availability of individual resources, which fail much more often, may be a
useful indicator of the performance of the overall function.

with the state safety programme referred to in Standard 3.1.1 of Annex 19 to the
Chicago Convention in its first edition of July 2013.

describe any changes to it as compared to the previous plan.
(2) The annual plan shall cover the following provisions on the level and quality of
service, such as the expected level of capacity, safety, environment and cost-
efficiency:
(i) information on the implementation of new infrastructure or other
developments, and a statement on how they will contribute to improving the
performance of the air navigation services provider or provider, including level
and quality of services;
(ii) performance indicators, as may be applicable, consistent with any
performance plan that may be required pursuant to Chapter IV of Part 1 of
the Transport Act 2000, against which the performance level and quality of
service may be reasonably assessed;

by the air navigation services provider, including safety indicators to monitor
safety risk and, where appropriate, the estimated cost of mitigation
measures;
(iv) the air navigation services providers' expected short-term financial position

request, under the conditions set by the competent authority in accordance with
applicable law.
ATM/ANS.OR.D.010 Security management

required in point ATM/ANS.OR.B.005, establish a security management system to
ensure:
(1) the security of their facilities and personnel so as to prevent unlawful interference
with the provision of services;
