Max PAX Explained
EHM-1199 Philip:
Fim fims idea of based on previous flights sounds great but with a randomised function could create very unrealistic totals. If the function returned a slightly lower number than average then the number being used for future flights would also be lower resulting in a downward trend for that route. Ultimatally we could end up with a large plane and almost no passengers which would be highly unrealistic and against the grain of what any routine like this is supposed to achieve.
What are the industry averages for %pax. These must be available somewhere and if not could be obtained just by taking a poll of routes we have fly in real life and the number of empty seats. I would guess that the figure rarely drops much below about 80% and is probably usually between 95 and 100%. It would certainly follow a normal distribution curve so you would find say 95% of the flights are within the 95-100% capacity pax band. (These are my guesstimates and need testing.) In which case the solution could simply be a controlled band for a random generated number. 95% of the time then, the pax would generate in the band indicated and the rest of the time outside the band. The maths is fairly simple it's just finding the data to produce that normal distribution curve that might be more tricky.

For my own flying, I think I'll probably just make a simle program, giving me a random number within the range you described, I personally don't thing that the pax is so important to be exact numbers following the real life trend. It just seems too much work and too little to gain. But again, if it's possible to do it in an easy and elegant way, why not. :)
Thank you.

In which case fimfim why not just let the PIREP do it for you. That's more or less what happens if you leave the pax blank on the PIREP. It does a calculation of I think between 75%-100% and fills in the blank.;)

I've done it so far. :) But that way I don't know anything about my dear passengers, I let them in, fly from A to B, and let them out. But after all, that's what air travel is all about..hm.. Maybe cargo is more my thing.. :)

We need some sort of conversation parsing software to generate chat as they board and maybe it could also create tickets with simulated addresses. Hey, one of us could check the simulated passports match the faces.;)
Better still, we could have a simulated drunk trying to board and then we could in a simulated way of course, kick his butt right off our aircraft and refuse to fly him ... oh ... the possibilities are endless.;D
