The low cost fix is to fix the FPRSA-R software. The front-end proxy cannot easily detect code collisions because such code collisions are not readily apparent. The ICAO flight plan allows omitting waypoints and it is one of the omitted waypoint that collides with a non-omitted waypoint. If you have taken the trouble of introducing such a sophisticated code collision detection in the front-end proxy, you might as well apply the same fix to the real FPRSA-R software.
- ggm 2y agoMy primary fear was the compliance issues re-coding the real s/w would drive this into the ground, where the compliance for a front fix might be lower. You could hash-map the collisions seen before and drive them to a "don't do that" and reduce the risk to new ones. "we fall over far less often now" Thank you for neg votes kind strangers. Remember ATC is rife with historical kludges, including using whiteout on the giant green screens to make the phosphor get ignored by the light gun. This is an industry addicted to backwards compatibility to the point that you can buy dongle adapters for dot-matrix printers at every gate, such that they don't have to replace the printer but can back-end the faster network into it.
