-== Methods for implementing VNAV ==
-#<big>(virtual flight-testing database)</big>:
-Instead of doing all this "live" inside the FDM via a reverse solver, another method would be doing virtual test flights and gathering the required flight data to come up with a virtual PerfDB, i.e. actually write test data to some form of database (eg. SQLite) so that this could be queried at runtime in FG.
-'''What is required to apply this method?'''
-* data analysis to determine the scope of fields, and the domain of values for the gathered data (the domain of units, and relavent data for VNAV's trajectory functions)
-* an agreed standard of tests applied to all airplanes (climb/descend profiles with different configurations)
-* an agreed format(data file structure) in which this data is formated, or using an improved database approach and provide mapping via a DBMS for a changing file structure
-* an agreed property *list inside flightgear to hold this data (a single property won't suffice)
-* an interface for flightgear to query the data file through the DBMS (FlightGear's scripting language Nasal does have SQLite bindings, another option would be a flat text/XML file)
-* a way of implementing this data into the aircraft's model(usually xml file)
