Prior Compliance List of Aircraft Operators Specifying the Administering Member State for Each Aircraft Operator – June 2014
Prior compliance list of aircraft operators specifying the administering Member State for each aircraft operator – June 2014 Inclusion in the prior compliance list allows aircraft operators to know which Member State will most likely be attributed to them as their administering Member State so they can get in contact with the competent authority of that Member State to discuss the requirements and the next steps. Due to a number of reasons, and especially because a number of aircraft operators use services of management companies, some of those operators have not been identified in the latest update of the EEA- wide list of aircraft operators adopted on 5 February 2014. The present version of the prior compliance list includes those aircraft operators, which have submitted their fleet lists between December 2013 and January 2014. BELGIUM CRCO Identification no.

People, employees and customers, not products and machines, must be the arena of an organisation’s core competence. The success of an airline, like any other business organisation, depends, to a large extent, on managerial decisions affecting the organisation’s structure, strategy, culture and numerous operational activities. The industry is a knowledge-based service market that requires practitioners or managers to acquire a sound knowledge of management theory and practice. There are some managers who are capable of taking right decisions owing to their practical experience on the job. Others are able to do so because of the knowledge they acquired in the school. All in all, academic knowledge is not a waste as it provides reasons for decisions taken. -
