Sequence Diagram MaintenanceFailCheck
package:
The Maintenance Inspector sees an aircraft ready for maintenance on his screen, and sends a team to carry out the safety check (this is not part of SAAMS). When the team returns they report that the aircraft has failed its check. The Inspector notifies SAAMS of this, entering a text description of the problem. Some time later the repair is complete, and the Inspector notifies SAAMS of this.
Note: The messages following each "notifyObservers" are omitted, as they are (may be) 'broadcast' widely in the system.

Class AircraftManagementDatabase
|
public class AircraftManagementDatabase
A central database ("model" class):
It is intended that there will be only one instance of this class.
Maintains an array of ManagementRecords (MRs), one per potential visiting aircraft. Some MRs hold information about aircraft currently being managed by SAAMS, and some may have the status "Free".
The index of each ManagementRecord in the array is its "management code" ("mCode"), and the mCode of any particular visiting aircraft's ManagementRecord must remain fixed once it is allocated.
Many classes register as observers of this class, and are notified whenever any aircraft's (MR's) state changes.

public class FlightDescriptor
Contains all details of a flight: the flight code, itinerary and passenger list.
This is the package of information downloaded from an aircraft by the RadarTransceiver as the aircraft enters Stirling Airport's airspace.
Not obvious from the class diagram is that the RadarTransceiver boundary class should construct a FlightDescriptor when it "detects" an aircraft, and passes that object to the AircraftManagementDatabase as the parameter of a radarDetect message. (Since this will probably/possibly be local to an event handler method in RadarTransceiver, there is no attribute association from RadarTransceiver to FlightDescriptor.)

public class Itinerary
Describes an aircraft's flight plan.
An aircraft entering an airport's airspace has come from the "from" airport, and wishes to land at the "to" airport, before travelling on to the "next" airport.
So, an aircraft whose flight descriptor contains an itinerary with "Stirling" as the "to" attribute wishes to land at Stirling now, otherwise it is just passing through local airspace on its way to its destination.
Incoming flights supply their Itinerary in their flight descriptor, and the ManagementRecord for the flight extracts the Itinerary and holds it separately.
Outbound flights have their Itineraries uploaded to the aircraft as it departs in a newly built FlightDescriptor.

public void PassengerDetails(String name)
Constructor: Just a name required.
public String getName()
Return the name of this passenger.
public class PassengerList
Contains an array of PassengerDetails objects - one per passenger on a flight.
Incoming flights supply their passenger list in their flight descriptor, and the ManagementRecord for the flight extracts the PassengerList and holds it separately.
Outbound flights have PassengerLists built from passenger details supplied by the gate consoles, and the list is uploaded to the aircraft as it departs in a newly built FlightDescriptor.

public class RadarTransceiver
An interface to SAAMS:
Radar tracking of arriving and departing aircraft, and transceiver for downloading of flight descriptors
(by aircraft entering the local airspace) and uploading of passenger lists (to aircraft about to depart).
A screen simulation of the radar/transceiver system.
This class is a controller for the AircraftManagementDatabase: it sends messages to notify when a new aircraft is detected
(message contains a FlightDescriptor), and when radar contact with an aircraft is lost.
It also registers as an observer of the AircraftManagementDatabase, and is notified whenever any change occurs in that <> element.
