Daily maintenance shot up to 50m, from 21m!!

[dorea42]

Hello all, I am currently playing in private world #510 "ninervictor", airline ID #11489

I had 12x A340-300 delivered to me recently.


Before the new month, I noted down my MX to be €21,714,420. However, after the game cycled to month of June 1996, my MX shot up to €50,654,569

I also did scrapped about 6 to 7, 8 years old A320 before the new month.

My fleet as follow:

BEFORE:

Airbus A310-300     40
Airbus A320-200    162 (5 on order)
Airbus A340-200    9
BAC Concorde 0 (1 on order)

AFTER:

Airbus A310-300     40
Airbus A320-200    162 (5 on order)
Airbus A340-200    9
Airbus A340-300    12 (2 on order)
BAC Concorde 0 (1 on order)

Any idea what's wrong guys? BUG maybe?
I really doubt that 12 new planes can cause the MX to shoot up by about €29m!
Beside, A340-200 and A340-300 are '1 family'

[dktc]

Expensive, large aircrafts have higher maintenance. Your 12 new aircrafts are all A340-300's

[pseudoswede]

Yup, calculations look right.

As repeated over and over again in these forums, planes over 200M are not worth buying.

[dorea42]

I am aware that larger aircrafts have higher maintenance, but I was totally caught off guard when MX shot up by approx 29m!

Reason? When I introduced my A340-200, my MX didn't increase by much. Infact, 21m is all needed for my 342 + 310 + 320..

If I get rid of all my remaining 342, will the MX fee drop back to 20+m?

[dorea42]

I checked with my friends who played this game..

and he has much larger fleet of big planes compared to me. Guess what? His MX had a drastic drop - more than 2x.

Weird isn't it?

If you got rid of all of your A340s and your Concorde, you might be closer to 25-30M.

So what large jets can I get then?

I still find it ridiculous because I checked with my friend, the world creator, and his mx is only about 36mil daily.

My fleet now:

Aerospatiale-BAC Concorde   1   (1)
Airbus A310-300   42   (1)
Airbus A320-200   163   (3)
Airbus A340-300   15   (2)

MX cost daily: €50,495,977 - Note that the huge jump already happened even before I have the concorde.

My friend's fleet:

Airbus A300-600R   1   (0)
Airbus A310-200   35   (0)
Airbus A310-300   32   (0)
Airbus A320-200   174   (0)
Airbus A330-300 LR   58   (0)

Boeing 777-200   32   (0)
McDonnell Douglas MD-11   19   (0)
Boeing 777-200ER 0     (25)


MX cost daily: about €36+ mil

Note: I did not post this thread in "BUG" forum because I believe this may just be a glitch that just need to be rectified, and not a bug, as yet..

[pseudoswede]

Please post the actual numbers on the 1st of the month on the Finance Report page for both of you.

You also never stated the average age of your (or your friend's) fleet.

[phat01]

i know the answer is probably yes, but does the maintenance go up as you planes get older? i have seen it slowly creeping up my oldest planes are 3 years old.

[CHR]

Yes, maintenance goes up as your planes get older. 3 years is an alright age for planes, however much older than that and it becomes cheaper to buy a new plane. I would be thinking about replacing those older planes soon. If your friend has significantly younger planes (especially if the big/expensive planes are younger), they would likely have a considerably lower maintenance.

[dorea42]

Somehow I can't get into this forum for quite a long while.. kept getting "page cannot be displayed" message..

anyway, when the comparison was made, his fleet age is definitely older than my 343.. my 343 was just about "fresh from factory".

anyway another player in my world, SJY, told me that his mx dropped drastically from 28+mil to 13+mil. It just happened, and after delivery of 772ER


PS: When I posted the comparison, my average fleet age was 3.0... now my average fleet age is 3.9

Hi, I would like to bring the attention to the admin about this weird problem that just occured to me and my friend in the above mentioned Private world.

Current Fleet as of now.

Aerospatiale-BAC Concorde   2   (0)
Airbus A310-300   35   (5)
Airbus A319   20   (0)
Airbus A320-200   55   (0)
Airbus A321-200   25   (10)
Airbus A340-200   15   (0)
Boeing 737-200 Adv. HGW   1   (0)
Boeing 767-300ER   3   (0)
Boeing 777-200ER   15   (2)

Maintenance (Yesterday)
Daily Maintenance Costs: € 28,132,760

Maintenance (Today)
Daily Maintenance Costs: € 13,303,809  <<<<<  

Aircraft Statistics
Average fleet age: 1.6 years

What i did before the drop?
I put up 3x 763ER for sale.
1x 772ER and 3x A310-300 Delivered.

There should be an increase in MX i supposed? Since the 3x 763ER is not sold yet, i am still paying for the MX.
It make no sense for it to have a sudden drop, while dorea42 has a sudden increase.
Something is seriously wrong here.

I hope the admins will take a closer look at the problem? 

[ATE24]

I've problem on the maintenance as well...

In the past year I've been replacing all those 5 year old aircrafts and reducing the average age from over 3 year to 2.1 year right now. But I realize that no matter how I replace the aircraft the maintenance continues to increase. I really see no reasons on this issue, could anyone explain it to me?

[kcclieou]

My maintenance cost is hitting me hard. I had not been expanding my fleet over the past year and instead focused on scrapping old airplanes and replacing them with new ones of the same model, though this was not something I did every single month. It turns out that the aircraft maintenance cost increases LINEARLY irrespective of the number and types of airplanes I scrap over the previous game month. This appears to be pretty weird since, at the beginning stages of the game, I noticed that the maintenance cost of each single airplane increased linearly. I would sort of suspect that the script for the calculation of maintenance expenses is recursive in nature, rather than adding up the cost of each individual airplane at the start of every month - am I correct?

[StephenM]

I would sort of suspect that the script for the calculation of maintenance expenses is recursive in nature, rather than adding up the cost of each individual airplane at the start of every month - am I correct?

The formula is based off aircraft values, however all inputs in the formula are summed together prior to being handled. As a result if maintenance costs were calculated per plane individually, and the maintenance cost was summed at the end, the result is not the same as what the formula currently does. The current approach allows for much faster processing time however, when scaled across 3-400 worlds it does the job fairly effectively.

The formula isn't perfect, but I cannot really comment on a case by case basis unless I start pulling data on each persons fleet and number crunch it that way.
