1. User Preferred Trajectories in Commercial Aircraft Operation: Design and Implementation
Sammanfattning : This report describes how an aircraft creates and flies its User Preferred Trajectory from take-off to landing, based on the objectives and constraints the aircraft is subjected to from a technological and operational viewpoint. A basic description of commercial aircraft operation is given, with an emphasis on identifying the different stakeholders (Air Navigation Service Providers, Airline Operation Center, Pilot/Aircraft, Airport and Civil Aviation Authority).

2. Part-out Based Spares Provisioning and Management : A Study for Aircraft Retirement
Sammanfattning : The operation and maintenance phase of a complex technical system may deal with strategicdecisions for asset retirement and end-of-life management. When a fleet of aircraft reachesthe retirement phase, the operation of remaining fleet should still be kept at a defined level ofavailability. LÄS MER
3. Aircraft scheduled maintenance programme development : decision support methodologies and tools
Sammanfattning : The air transport business is large in its operations, integrated, automated and complex. Air carriers are constantly striving to achieve high standards of safety and simultaneously to attain an increased level of availability performance at minimal cost. LÄS MER
4. Models for the Procurement of Subsidized Air Services : Conventional Aircraft and the Adoption of Electric Aircraft
Sammanfattning : In liberalized air transportation markets, governments often adopt subsidy schemes through which they ensure air services along routes that are deemed commercially non-viable but economically and socially essential. The objective of these subsidized air service routes is to ensure a minimum level of services to outlying communities or remote regions that are difficult to access—by other modes of transportation—from the capital, other main cities or a hub airport yet can not be served commercially due to thin demand.

5. Health Monitoring for Aircraft Systems using Decision Trees and Genetic Evolution
Sammanfattning : Reducing unscheduled maintenance is important for aircraft operators. There are significant costs if flights must be delayed or cancelled, for example, if spares are not available and have to be shipped across the world. LÄS MER
