Load factor - weird
« on: July 27, 2012, 05:10:17 PM »
Hi all,
I have plenty of flights between CGH e SDU, most of them with very good load factor. However I can't explain why something like this below is happening, provided that the price is the same for the two routes and none of them is flying a weird early morning or late night schedule.It's also the same aircraft type, B722. Any idea?

You have two flights leaving at the same time. One at 11:30 the other at 11:35.

You can't have two flights going to the same destination leaving that close together.  The code sees the two movements as one airplane.

I don't get it. If I have 30 flights a day between the two airport they necessarily leave very close in time given a day has only 24 hour (and even less useful hours).
Also why one of the flight is flying empty and the others are not? Even if the system sees it at one flight only, there is plenty of demand to fill all my capacity...
still not sure I get this...

Thing to force players to make sensible scheduling, and not make their 4x747 to depart on the same minute to same destination every day.

(= since some wish to play some things "unrealistically" we have to "force" them...)

If you have 30 flights/day, then yes, some will have to leave close together. But in this case, close together means 30 minutes.

5 minutes separation is too close, and will be penalised.

Scheduling flights very close together was basically a way to rort the system, and so Sami fixed it.

To play it safe, on most routes, you should never have flights leaving with a gap smaller than 1 hour. On very busy routes, like CGH-SDU, you should never have flights leaving closer together than 30 minutes.

The thing is, how do you cover the huge CGH-SDU demand where SDU's runway is 1320m? Sometimes this is impossible unless you have flights departing at 5min intervals.

A 722 appears to get 88% of its default pax thanks to the short distance and low fuel load, despite needing 1900m of runway fully loaded (SDU-GRU currently has 2 722 flights, and 286 available pax.) So I'd assume you could run 737-400, 737-800, a320-200 all with 140+ pax as well. I'd guess you could put a a321-100 on it, and get ~165 pax per flight available.

There's a 4 hour curfew at one end, but you've still got 20 hours to use. 20 hours with 30 minute spacing means 40 flights, ~6600 pax with a 321. 20 minute spacing, that goes up to ~10000 pax. There's 6-7k demand.

So you can definitely oversupply the route, never having flights closer than 20 minutes. It's just a bit of an extra logistical challenge.

Because its demand is way more than one airline can handle without tripping safeguards in place to keep the game fair for all is not a good reason to remove those safeguards. As far as this airport is concerned, one just has to accept that runway limits and aircraft availability will always mean one airline cant mop up all the demand on its own on this particular route.

Not necessarily a bad thing tho, run the maximum flights you can, then when you get high RI and/or 90+ LF's, hammer the prices and, effectively, get the same revenue as running extra planes without the cost of doing so.

Or, alternatively, petition Sami to reduce the demand figures so that who-ever is flying the route can have the joy of maxing supply to it.

My choice would be keep the demand and max the prices tho....

I don't think I got the answer I expected. Also you have to take care of slots availability and how a route would fit with a plane overall schedule before saying you can move one flight from where it is. The window to operate the route is very limited cause you can't leave before 4.30 am and after 10 pm.
By the way the 722 is limited to 124 pax at SDU from an original standard capacity of 162. I don't know how but today in real life I fly there on a 738 or 320 with no payload limitation.
Thanks for the explanations

1. You have some flights shceduled too close together = reduced LF on those flights
2. You have some flights departing sooner than 5:00am = reduced LF on those flights
3. You have some flights scheduled correctly (as per game rules) = different LF on those flights compared to point 1 and point 2

Those 737-800s operated in Brazil have the short field package which Boeing offers to enable them to do so. Perhaps such improvements were not available on the 727 (although it was designed for metropolitan airports, I guess 1300m is too small). Have you tried using the highest MTOW B722? That should help runway performance.
