35396 - Air Transport M

Learning outcomes

The course deals will the analysis of air transport systems and their performances due to the interactions among the several transport elements. Transport systems are the results of the interactions among several elements that affect one another in both direct and indirect ways. The course wants to provide students with basic skills and competencies for the functional design of the components of an air transport system - by modelling transport supply and demand - and for the assessment of its impacts and performances.

Course contents

The air transport system - The aspects of air transport planning - The main actors that interact in the planning of an air transport system - The coordination action: subjects with Regulator function and Provider function - International organizations (ICAO, ECAC, EUROCONTROL, FAA, IATA, ACI) - The functions of ENAC and ENAV - The subsystems of supply and demand in the air transport system - The airport node - identification code and classification - node location and accessibility - Functional layout of spaces in the land side - centralized and decentralized structure - Configuration of the airport node on the air side - main planimetric schemes - Choice of the airport: the main factors for passengers and airlines - the attractiveness of an airport - competition between airports - The general cost of air transport for passengers - Service level and dwell time in the terminal - Slack time - monetary costs of travel - The general cost of transport for airlines: time and money costs - blocking time - Main elements of the air side - runways and their configuration - taxiways and connections with runways - aprons - Capacity of the air side - definitions of airport capacity - capacity of parking areas and taxiways - Capacity of the runway: definitions - Factors affecting the capacity of the runway - Lift, whirlwinds and separations between aircraft - Orientation of the runway - Method of the wind rose - Control systems and separations between aircraft - Estimation of occupancy time and average interval - ROTA and ROTD - Time rates contributing to the determination of ROTA and ROTD - Space-time models for capacity calculation of the runway - the removal of simplifying hypotheses on some variables - Overview of queue models for the calculation of the average delay on a runway - Air service networks - Hub-and-spoke model and point-to-point model - Wave systems and minimum connection times - Comparison of organizational models: traditional companies vs. low-cost airlines - Territorial continuity and public service obligations - The air traffic management system (ATM) - Air Traffic Flow Management (ATFM) - Air Navigation Service Provider (ANSP) - The Air Traffic Service (ATS) component - The air traffic control (ATC) - Subdivision of the airspace and related control bodies - Airways: general characteristics - Separations between aircraft - Air transport demand: general characteristics - Levels of demand in the peak hour (or period) (models of queues) - Notes on the use of time series models for estimating the demand trend - Discrete choice models for estimating the demand for different dimensions of choice (air mode, company, airport) - Competition / integration between aircraft and fast train - Elements of identification of the "fast train" system - fast train / air report - Measures of performance of an airport node - Operational, economic, environmental performances - The product impacts -

Teaching methods

Lectures and Practical / Workshops

Assessment methods

Written test made by theoretical and practical questions. Questions will concern the course contents, as described in the detailed program. The goal of the written test is to evaluate students’ knowledge and their ability to apply such knowledge in a working environment by using a system approach able to link the functional design of a single transport element to the transport network analysis and the produced effects.
