EFPS
EFPS is produced by NAV Canada. They develop new products with ATC by delivering limited functions and then working with ATC to refine them and then adding more functionality.
In this way ATC don't get hit by all the change in one lump and they also get involved with the process which means ATC get a tool that is more likely to work the way ATC want and need.
The current ADIS system is at end of life so something had to be done to replace it and that something has to cater for the here and now and the next ten years or so. So change is inevitable and EFPS is a lot better than the other contenders.
