The Influence of Unplanned Technical Services on Aircraft Fleet's Management

摘要

In this paper the influence of introduced airworthiness directives and bulletin services on in-service process were described. During the in-service time two main states can be distinguished: exploitation and service. An aircraft is an example of technical object in which exists strong relations between these states. The main aim of any airline is to maximize its profits. Such an optimization is affected by several factors. They are mainly connected to the service state (service cost minimization) as well as to the exploitation state (flight interval minimization, frequency ratio maximization, work waiting time minimization, etc.)
