34 * This class implements the Facade design pattern (GOF p.185) to provide
35 * a single, (deceptively) simple flat interface for the FlightGear
38 * To help cut down on interdependence, subsystems should
39 * use the BFI whenever possible for inter-system communication.
42 * - add selectors to switch the current plane, throttle, brake, etc.
43 * - add more autopilot settings
49 // Initialize before first use.
52 // Reinit if necessary.
