You are right. Prediction will not be possible but what could be done is that FG moves the craft in a way that it best estimates and then correct it the moment it gets an input. Of course this does not eliminate the choppy moment completely as it might suddenly shift location if there is an error, which is most likely to be there. FG estimate can be made better supposing a equivalent performance model of the aircraft was being used in the sim too. Speaking of this.... Which modeling technique would best simulate an aircraft model? and are there any guides to making these models? -- Cheers!
