Greetings
How can you implement new leg types; such as RF, in an old platform that was not design to handle these leg?, HWL is not a fortune telling company, it is an excellent Avionics company whom did not let its customer down, despite the fact that these customers didnot want to upgrade their equipment

Now for the record, on the Airbus FMS2 HWL is well ahead of Thales when it comes to RNP RNAV.
Anyway I am still convinced that you dont know what you are talking about

Dont take it personally take it on the rock
