Unit vi management




Management decisions have an impact on flight safety. Managerial defi- ciencies have increasingly been identified as contributing causes to accidents and incidents. This was recognized by ICAO in Flight Safety and Human Fac- tors Program which is aimed at the management of civil aviation administra- tions, operators, and decision-makers in the aviation system. The influence of management on flight safety has been often overlooked. It’s easy to illustrate the important role of management in promoting flight safety. The safety impli- cations of flawed decision-making and poor safety management are evident.


Safety through management


Aviation is a complex system and requires the precise co-ordination of a large number of human and mechanical elements for its functioning. As a sys- tem, it possesses elaborate safety defenses. Accidents in such a system are the product of the combination of a number of causal factors. Breakdowns are the consequence of human decision-making failures which occur primarily within managerial sectors.

Failures can be viewed as follows:


1. active failures, which are errors and violations having an immediate adverse effect, and are generally associated with the «end-user» (pilot, control- ler, mechanic, etc.);

2. latent failures, which are decisions or actions, the consequences of which may remain dormant for a long time.

Latent failures are present in the system well before an accident, and are most likely bred by decision-makers, regulators, managers and other people far removed in time and space from the event. Latent failures have their primary origin in errors of the decision-makers. Even in the best run organizations, a significant number of important decisions will prove to be wrong. Since these wrong decisions cannot be prevented, steps must be taken to detect them and to reduce their adverse consequences. Fallible decisions in line management may

take the form of inadequate procedures, poor scheduling or neglect of recogniz- able hazards. They may lead to inadequate skills, inappropriate rules or poor knowledge or they .may be revealed in poor planning or workmanship. Fallible decisions by line management may breed conditions, under which end-users may unknowingly perform unsafe acts. For example, deficiencies in training may translate into high workload, undue pressure under time constraints, inap- propriate perception of hazards, or ignorance of the system. These conditions may be further aggravated by environmental influences or by the presence of hazards. There is a direct relation between management deficiencies and acci- dent/incident precursors. Deficiencies in training may lead to precursors such as high workload which may co-exist with failures in maintenance and in schedul- ing which in turn may also increase workload and pressure. At the same time, failures in system control may allow pairing of inexperienced crew members or operations under unacceptable adverse conditions. Latent, failures which lead to accidents are type causes, while active failures which cause the breakdown of defenses are only token causes. Deficient training for example, is a type cause which can give rise to a variety of token causes. Remedying a type cause can eliminate a large class of token causes. One of the pillars of safety is sharing experience-collective, analyzing, discussing and publishing safety information. The air carriers and countries which are leaders in safety are always ready and open to talk about safety problems.




When asking ourselves how future occurrences can be prevented, all the factors need to be considered. Reform actions-teaching pouts to be aware of in- sidious visual illusions or the limitations of operations into contaminated run- ways, should help to prevent similar occurrences at any airfield. The pilot’s per- formance is the logical result of an inconsistent training system and the defec- tive policies of management both at the airline and the aviation administration. No flight crew can be expected to cope with situations for which they have not been properly trained.

Adequate reform action by the airline entails the following steps:




         reappraisal of the airline training system and rules to provide for stabil-


         the implementation of formal procedures for instructor selection and




     the appointment of a flight safely officer and the establishment of a safety information system;

         the re-evaluation of the dispatch and flight-following system;


         the implementation of schedules which reflect a degree of realism. Verification of pilot competency is a responsibility of the authorities. Global action should be undertaken to bring the aviation system up to date

in terms of communications, navigation and approach aids, and infrastructure and weather information dissemination. The response of management to safety information is vital.


Airport Management


A trend is to establish autonomous authorities to operate airports and route facility services. Five of Canada’s major airports were transferred from federal government operation to 4 independent management groups known as local airport authorities. In New Zealand a civil aviation authority was estab- lished, to take over the functions of the air transport division. New Zealand had previously established publicly-owned corporations to operate a number of air- ports and a State-owned enterprise to assume control of airways services on a commercial basis. Vienna Airport Authority was transformed into a joint stock company in which 27 \% of the shares were sold to private interests to provide capital for airport expansion. Prior to tills development within Europe only the British Airports Authority, primarily London area airports, had such extensive private involvement. In Germany preparations were finalized for the establish- ment of a new government-owned, autonomous authority that was to take over responsibility for the provision of air traffic services from the Federal Adminis- tration of Air Navigation Services
