Maestro is a multi-airport and multi-runway decision making tool for airport terminal area Management. The system aims to optimise the airspace and runway capacity by distributing the workload associated to arrival and departure control among individual ACC, Approach and Ground controllers, thus minimising delays and excessive fuel consumption.

To achieve this goal, the system provides Approach, ACC and Ground controllers with graphical views of the computed sequence and the control actions that have to be taken to properly expedite the traffic. Throughout this process, the controllers remain fully in charge of the sequence as MAESTRO enables manual changes to test various sequencing options.

Arrival Management AMAN:

• Handles Flight Plans and Radar Tracks from the local FDPS and RDPS systems;
• Allocates each incoming aircraft to a destination runway taking into account runway allocation rules, runway restrictions for handling noise abatement procedures, selected TMA configuration and runway separations and flight priorities.
• Calculates its optimum Scheduled Time of Arrival at the TMA entry fix (STA FF) and at the runway threshold (STA) and the delays to be absorbed with respect to these times;
• Optimises the overall sequence to minimise the global delay and holding pattern situations;
• Displays the sequence and supplies the ACC and Approach controllers with the corresponding Control Actions to absorb these delays;
• Generates automatic coordination messages to relevant positions when the sequence is modified by one of the controllers.

Departure Management DMAN :

• Handles flight plans, CFMU slots, ground tracks from local FDPS, ATFM and A-SMGCS systems;
• Shares runway information with AMAN (closures, runway configuration);
• Enables assignment of departure runway and the corresponding holding point according to off-line defined rules and to information shared with the AMAN function (runway configuration and separations, runway closures);
• Computes Natural Take-Off Time according to EOBT, slot constraints and average taxiing times (taxitime might be provided by an external system if exist);
• Establishes and optimises the departure sequence for each runway according to Flight priority (e.g.: sanitary flight), Runways constraints (departure rate, wake vortex separation, runway closures) and Arrival flights;
• Displays on all concerned Ground, Tower Approach and ACC control positions the computed sequence providing to all concerned actors a common view of the departure traffic.
