The aviation community is under constant pressure to reduce accident and incident rates, while optimizing operational costs to remain competitive. Flight Data Monitoring (FDM) offers an efficient solution to this challenge. This quality assurance process, which consists of downloading and analyzing aircraft data on a routine basis, is now being used by operators throughout the world to facilitate corrective actions in a range of operational areas, including safety, operations and maintenance.
By offering the ability to track and evaluate flight operations trends, identify risk precursors, and take appropriate remedial action, FDM strongly contributes to increased flight safety and operational efficiency.
* Using data to help in the prevention of incidents and reduce their associated costs.
* Operational insight.
* Improved fuel consumption.
* Reduction in unnecessary maintenance and repairs.
* Adherence to noise restrictions and fine reduction.
ECTM is the continuous monitoring of key engine parameter to detect impending failures and assess engine performance.
* Minimized unscheduled downtime and optimized on-wing times
* Supports early line maintenance decisions to avoid secondary damages and AOG’s.
* Supports performance prediction and optimum aircraft operational planning.
* Allows for better engine removal planning and optimized spare engine management.
* Allows for optimized off-wing maintenance planning.
* Increased fuel efficiency and overall fuel consumption thanks optimized core engine cleaning.
* Lower maintenance cost.
The reliability program of aircraft in operation and maintenance is a combination of statistic monitoring and recording of the events associated with the airworthiness of an aircraft. The results obtained by monitoring reliability in operation may serve as a basis for supplementing or modifying the aircraft maintenance program; such changes would indicate the malfunction of components or systems manifesting lacks and the need for early control, or replacement during utilization.
On the basis of the reports on reliability monitoring of air carriers’ maintenance services, the aircraft manufacturer collects and analyses the data for a large number of aircraft, thus being able to establish which are the systems and respectively components of the aircraft that cause problems in aircraft operation in most cases.
A feedback on functionality, i.e. on the problems occurred during aircraft operation plays a big role and is of high importance in aircraft maintenance. Information that the air carrier can and must deliver to the aircraft manufacturer gives the manufacturer a possibility to collect and process data for a large number of aircraft seen as a fleet. On the basis of these data the manufacturer may identify the systems and/or components due to which problems in aircraft operation most often arise. If a defect in manufacture is established, modifications and installation of new components are introduced by the aircraft manufacturer, which should provide an increase of reliability in maintenance and operation. Also, an air carrier is obliged to deliver reports on reliability monitoring to aviation authorities as a proof that aircraft structure, power plant, its components and other systems are capable of achieving and maintaining reliability levels high enough, which is the basis for safety of carrying out aircraft operations.
