Max PAX Explained

[EHM-0188 Andy]

How did/do you all fill in the number of passengers on your PiReps ?
Do you fill in a random number or do you use a tool that calculates it ?

[EHM-0240 Joe]

I think the way it used to work was if you used the online pirep form then you can put whatever you want, and if you didn't put anything then it was automatically set as the aircraft being 3 quarters full.

If you used the flight logger to submit the flight then when you select the aircraft you used, the number of passengers was automatically set to an amount somewhere between 2 thirds full and completely full.

Thats roughly how it happened anyway, the numbers probably aren't exact.

[EHM-0188 Andy]

I used a randomize formula in MSExcel to calculate the number.
I just wanted to know if anyone used a certain tool.

Or is there someone that can make such a tool ?

[EHM-0005 Maarten]

As Joe said, if you don't fill in anything in the PIREP form then it takes a random number. It takes around 80% of the aircraft's capacity if you leave the field empty.

Using a randomisation tool would not be very realistic unless you put a minimum cap on it......which i assume you did......for me i always fly with full load of passengers! :]

I will make one, it's pretty simple, and first version will be very basic. Just a minimum and maximum number of pax, and generated random nr. in that interval.

Maarten, may I use EHM logo for this one?
To make it official maybe...

Cheers

[EHM-0962 Zhen Yi]

And another quality product from EuroHarmony is in the works!

[EHM-1077 Emanuele]

Errr...  didn't quite understand what this
randomization tool would do differently
from what the PiRep does automatically
already.

Marteen said that if the field is left empty
the PiRep automatically put something
-around- 80%. Which probably means a
random number between 70% and 90%.

Sooo... what should this new tool do?

Manu

[EHM-0962 Zhen Yi]

Well......i guess it could allow the pilots to adjust the range according to current real world traffic trends? And of course it lets them know the number of passengers before hand and not after flying the flight! a tad bit more realistic i think

[EHM-1123 Dejan]

Manu, as I said it won't be anything fancy like logger was, nor will it connect through FSUIPC or something...  Just a tool to create pax in given interval, though I am open to more suggestions that may be added to make it more complex.
Feel free to post them here.

And since I don't fly anymore, at least not nearly so often, I plan to contribute through other means, even if I don't have a diamond on my badge.

I know of 2 existing tools for calculating the number of passengers.

1. Seats 2.0 from Michael Lyons
I tried it but I'm not able of changing the planes in the setup

2. Booking system from Ray Porteous for use with the VA Administrator software
(not freeware)

[EHM-1077 Emanuele]

The idea of changing the number of
passengers according to the trends
is quite cool and wouldn't have to be
implemented on the pilot's side, it
could be done on the server side.

The problem is: how do you find the
current trends? How do you find how
many passengers tend to fly between
London and Paris at any given time?
Or for any other location served by
EuroHarmony?

That's a good angle, making 'trends', hmmm..

Maybe to make it simpler, we should divide destinations into classes also, say 6-10 different, and calculate approx trend, given departure and destination index and some constant.

Example :
Schiphol >Class 1 > coefficient  9
Okecie > Class 5 > coefficient 5
Plane class(capacity) approx. 220
Passengers leaving: 9*5=45 percent, (there could be interval also, +-3-5%)

meaning plane will leave with 99  pax for Warsaw .....

Just a basic thought.

[EHM-1077 Emanuele]

That would be pretty elegant, but
if we knew so precisely how many
passengers fly between two location
just because of the size of the location,
we'd probably used a smaller plane,
wouldn't we? I wish we could find
some "live" data somewhere... or
past data we can extrapolate random
but not completely groundeless numbers
from....

Ciao ciao!

Manu

[EHM-0962 Zhen Yi]

Hmm....or how about human labour? Form a group of people who decide how the current trends are running? Doesn't exactly fit into EuroHarmony's automation but well it could be a temporary solution till there is a live source found......

[EHM-1199 Philip]

The problem with trends is that other than a major event at a route such as 9/11, trends tend to be airline specific. The trends for say EasyJet flying short continental routes from Stansted will be different from BA flight flying similar routes. Totally different marketting.

[EHM-0962 Zhen Yi]

Then the trends for BA would apply to the Main Division while the trends for easyjet would apply to EuroHolidays or something!

[EHM-0188 Andy]

You could takea few (4-5) airlines for each division to calculate the Trend

Euroharmony ->
 Average Trend of BA, KLM, AF, LH

Euroholidays ->
 Average Trend of Thomas Cook, Virgin Express, Hapag-Lloyd, ...

[EHM-0962 Zhen Yi]

And maybe also route trends or region trends?

[EHM-1199 Philip]

Sounds awefully complicated maths for hat would in essence still be an estimation and probably not a whole lot more accurate than the calculation already used. After all if most seats aren't sold the route gets dropped.

[EHM-0962 Zhen Yi]

True but in essence it would give rise to much more variations between routes, and i don't think EuroHarmony would play the game of dropping routes....

You are probably right ...
I made one just out of code, and it works, but I think most flyers will use it few times and then forget about it.
And since the logger sends data to server, there will be no use of it whatsoever.
Project halved, considering other options...

Hmmm, who's doing new EHM vTour?

I guess you have a lot more crucial stuff to think about, but I know I was first attracted here by it. If there are some text files left of the old version, I could make a new one.
Cheers

[EHM-1077 Emanuele]

What do you mean with vTour?

Manu

[EHM-0962 Zhen Yi]

Don't see any new tours around..........

[EHM-1367 Oscar]

what about this....

At 00:00 GMT, a certain amount of passengers are placed on each route... for example, 100 people. When someone chooses to fly on this route, the pax will automatically be set to X. This X is calculated by taking the 100 people (or whatever max is of the rute) and dividing it whith the previous 24 hour flights on the route. Example: Today five flights are made on a specific route. X=100/5=20. Tomorrow a flight on that route would be loaded with 20 passengers. I'm kinda tired now but wouldn't that after two days turn into a dynamic system, that changes day by day? Few flights previous day = fewer passengers = cut-downs on flights (fictional) = more passengers on the lasting flights = new flights to cope with the passengers (fictional). Wouldn't it work? Like in real life!

thank you.
