ATM/ANS.OR.C.005(b)(2) Safety support assessment and assurance of changes to
the functional system
ED Decision 2017/001/R
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.
