757-200 Turnaround time.
« on: March 07, 2013, 05:00:18 PM »
Just wondered why the 755-200 turnaround time at the +-1% delay factor is set at 1hr 55mins and the A321 gets away with just 1hr 10 even though the aircraft are basically the same size. I understand the 321 uses containers which cuts the handling time but 45 mins more seems excessive. Anyone any idea?

First and only question, why 1%?

(It's unnecessary to use such a long turn time)


(and also, 757 fleet group (-200/-300) is relatively much larger than the A320 series group (318-321))

Go on...

I've been aiming for 1% since I started 3 years ago.

You can also say the same about the A340-600 since its included in the A330 group, it has a much fast turn time than the smaller 777-200.

Yes please go on, I have always aimed for 1% delay on aircraft turnaround. I have also been playing for around 3 years have i been doing it wrong all this time Sami?  :-[

The thing is even if you achieve it (in your schedules), you are not going to get it.

I routinely get cancellation percentage (never mind delay percentage) higher than my scheduling would imply...

Your guys are not alone...I think everyone aims for 1%.
...it's not over until I say it's over

Yea, you are basically wasting time there.

60 mins for A320 series for example is what I consider a normal turnaround time (for intl flights with full service turnaround; the short hop quick turnarounds are not modelled yet as you know). It has some delay-% but it is always a tradeoff, either lost time or possible delays.

Delays in turn mean more marketing spending but on the other hand long turnaround may mean one flight less per day, depending a bit.

So there is no direct answer, but from game design perspective, it has been never intended that people use the very long turnarounds and stare at the delay probability indicator. (actually the 1% is also tad wrong looking at real life .. no matter how long turn time, there is always something that could go wrong and I'd bet it is higher prob. than 1% .. Though here the 1% means only the probability of delay due to too short turn, ie. no time for fuelling, cleaning etc)

In the future would it be possible to base the turn time for a given aircraft on

1. Number of seats (Simulates boarding/cleaning time)
2. Range/Next flight duration (Simulates fueling time)

This would fix the weird differences between aircraft of different sizes (767-200 and A340-600 can turn in the same time).

Turnaround times will be fixed to flight duration and fleet type in the future (to make it possible for example a 25-30min turnaround for A320 after a short domestic hop where no fuelling etc is needed, and so forth), however it's a very low-prio item in regards to other things. This has been previously discussed (in the correct subforum).

But one other thing than the possible hit on your CI (to be compensated with marketing) is the number of flights that get cancelled due to scheduling. You loose a big part of income here, not only CI points.

just WOW
for the whole time I've been palying AWS , I was trying hard to stick to 1% no matter what, even if I was loosing one more flight per day
this was a nice lesson for today!

Same here, 1%. However, 1% on some fleet groups (767, A330 at 2:10) is far more reasonable than others (757 at 1:55), but as Sami said it also depends on the mission the plane just flew. An A330 that just flew from JNB to LHR will, understandably, need far more time to prep for the next flight than an A330 that just flew LHR-AMS.

In my scheduling, I have noticed that there is a small decrease in on time percentage from 1% chance to ~8% chance, much smaller than the 7% decrease expected, so I normally feel comfortable going to 8% or so, but not much past that. But, I do still try for 1% chance of delay because until now, I thought there was much more benefit to that number than it seems there really is.

5 mins can jump you from ~1% to 8% depending on the plane.... I'll not take the chance....  If it goes from ~1% to 2% then by all means do it.

Re the 752, it doesn't need to be more crazily overpowered in this sim.
