Thanks for that BigDaddy
Let me see, Jepp give a nice story on how the system was built to calculate flight shots to the moon, but the darned system cannot check to see if a Airway is closed and its optimizer only a MTT does just that...but does no checks on anything
I don't think it is helpful to turn this into a "I think so and so is better than so and so" post however in regards to the quote above, I would argue that the functionality of ERAD/CRAM as well as NRP does indeed does just that. In fact I have just finished the SRS for S09 and found that Jep deals with the SRD a
whole lot better from my experience than the Germanic systems. Not sure what you mean by MTT though, at my desk it stands fro Mean True Track (you gotta love ETOPS!

).
Now in regards to your use of the word((s) 'optimizer and 'optimising' what exactly do you mean by this? Do you want to optimize on fuel burn? Time? Enroute charges? Cost? So in regards to the latter standard CI? or variable cost index? Does the system you are looking at allow you to create CI profiles for OEM ac that do not have any?
Also when do you optimize? A CFP created at -12 might not at all be the optimal plan at STD! Does a system allow you to make any LMC's to the CFP to counter act this?
Tankering - does a system to allow you to link flights? (not jusy ob and ib but follow on sectors). Fuel cost - different handlers different prices - can a system handle this?
I could go for quite a while yet - but rather than advocating one system or knocking another I would say to flight1540 take all these points above into account, as well as customer service (or technical support), system flexibility, road map etc etc.
And last but not least be wary of the teams coming out of Montreal (or Geneva)m coming to visit you in regards to fuel efficiencies, no hidden agendas there.......and we have fairies in our back garden too!
Whoops skipper calling on the old RT...better run!
