Yes, a good point. However, this is operator error rather than the flight
planning system's fault. Operators (under JAR-Ops) are obliged to flight
plan correctly. If they do not, it
could be caused by
anything from basic lack of training (to teach them awareness of SID's /
STAR's, RAD, CRD, UK SRD etc.etc.) to them
possibly
having received an incorrect IFPS-compliant from the IFPS systems at
Brussels/Bretigny. There are, of course, times where the flight planning
systems fail (due computer failures either local or mainframe, AIRAC cycle
incompatibility etc.etc.) I believe, and I have seen it from both sides of this
situation, that both
do try to do their absolute best.
