By the look of it the SITA system still have the same issue. But I must admit their performance database is very good, I remember they need much more details than Jetplan does. The backbone of the system constructed well, but the auto route feature still remains an issue. I still remember the code book, sometime too much function. I have used PPS while I was in Germany sample to use but not something I would recommend for a jet aircraft. Anyway I still preferred the old jetplan. Never try others, but would love to one day.
