// opengc_data.hxx -- Define structure of OpenGC/FG interface parameters
//
//  Version by J. Wojnaroski for interface to Open Glass Displays
//
//  Modified 02/12/01 - Update engine structure for multi-engine models
//                        - Added data preamble to id msg types
//
//  Modified 01/23/02 - Converted portions of the Engine and Gear accesssors to properties
//                          - Removed data from navigation functions. OpenGC provides own
//
// This file defines the class/structure of the UDP packet that sends
// the simulation data created by FlightGear to the glass displays. It
// is required to "sync" the data types contained in the packet
