Any tables defined are standard JSBSim tables with data suitable for your aircraft. I'm guessing that most people will not use the capability described in the original post, but for very large databases derived from extensive wind tunnel testing and/or CFD, the capability to model aero data higher than 3 dimensions may be needed. The mechanism for doing that was presented. It is up to the modeler to decide if that is needed or appropriate. In my case, with a very detailed aero database that is nearly a quarter million lines long, it is. Jon |
