23 * This file contains the class definitions for a (Top Level) traffic
24 * manager for FlightGear.
26 * This is traffic manager version II. The major difference from version
27 * I is that the Flight Schedules are decoupled from the AIAircraft
28 * entities. This allows for a much greater flexibility in setting up
29 * Irregular schedules. Traffic Manager II also makes no longer use of .xml
30 * based configuration files.
32 * Here is a step plan to achieve the goal of creating Traffic Manager II
34 * 1) Read aircraft data from a simple text file, like the one provided by
36 * 2) Create a new database structure of SchedFlights. This new database
37 * should not be part of the Schedule class, but of TrafficManager itself
38 * 3) Each aircraft should have a list of possible Flights it can operate
39 * (i.e. airline and AC type match).
40 * 4) Aircraft processing proceeds as current. During initialization, we seek
41 * the most urgent flight that needs to be operated
42 * 5) Modify the getNextLeg function so that the next flight is loaded smoothly.
