Fleet Commonality Data Collection

[Sanabas]

Plane delivered, plane put on the market, and the results:

115 planes, 130418/459342/443991

Add the caravelle, 167643/591569/571798, 129%.

So a bigger jump than it was 7 planes earlier. But far, far smaller than it was a few days ago with 30 less planes.

Still seems like something changed in the last couple of days. But did it change to still being exponential growth, just from a smaller starting point? Or did it change to fixed growth, but with a slightly bigger penalty for a large plane, rather than a medium?

I want more data.

My first new plane just arrived. It's a medium fleet, a HS748.

I've now got 122 planes across 4 fleets. When I went to bed, I had 3 Britannias, 73 Convairs, 42 Connies. I've now got 3 Britannias, 76 Convairs, 42 Connies, 1 HS.

With the increase to 4 fleets, the Bristol & Connie maintenance increased by 0.55%. Despite getting 3 more planes the total CV maintenance only increased by 0.4%.

Now it is definitely time for a bug report thread, as things seem to have changed again.

I will give you a data point for a very large fleet - after Wednesday game time (it is Monday in MT5).  I will get the cheapest small aircraft, increasing my fleets from 3 to 4, and we will see the results (to test if the large fleet gets a higher increase from 3 to 4 than a smaller fleet.  You already have 2 datapoints from me that showed that was the case.  I will test if it is still the case...

The hole thing seems completely strange to me.
Here some Data from my small Fleets:

Staring with
5 * AW650
9 * Connys
4 * L - 188
6 * caravelle

i set the Commonality / aircraft as 100 % here. First a new AW650 joines in, leeding to this:

AW650 - 89,92% Conny 100,73% L-188  96,63% Caravelle A new  100,73 overall - 97,10%

The next AW650 comes in:
AW650 - 82,78 Conny 101,46 L188 101,46 Caravelle 101,46 overall 96,24

An Electra arrives:
AW650 - 83,37 Conny 102,2 L188 88,45 Caravelle 102,19 overall 95,12

So? A new AW650 may or may not shorten the costs for an Electra, thats depends. It depends on, eh, what?

I wonder what will happen when my first Comet will join the zoo.

Add some data points.

I added 1 HS748

Before:

16 Britannia's: $478,990
22 IL-18B     : $662, 504
5 Connie's    : $203,300
                    $1,344,794
                     $31,274 per plane

After:
16 Britannia's: $517,349
22 IL-18B     : $672,360
5 Connie's    : $219,530
1 HS748       : $87,975
                    $1,497,214
                    $34,028 per plane, Increase of 8.8%

This is a stark contrast to my experience in MT5 where adding 1 764 to my fleet of 500 737NG's, E-Jets, and 787's triples my commonality costs.

So, prior to yesterday, all the fleet increases were almost an identical percentage, regardless of fleet type.

But yesterday, I had a smaller increase for my medium CV fleet than I did for my 2 large fleets, but all 3 jumps were tiny.

With 43 planes, you have an almost identical 8.0% increase for the 2 of the large fleets, but just a 1.5% increase for the third.

The numbers are getting stranger.




Your single HS748 is at 88k per month with 44 planes.

My single HS748 is 48.5k with 122 planes.

You pay 220k for 5 connies, I pay 460k for 42.

I pay 130k for 3 Britannias (I was at ~100 k for 1, 117k for 2, if I reached 16 my estimate is 300k), you pay 520k for 16.

Country you're in affects staffing costs & tax rate, so does this mean it also affects commonality?

In JA#5, I had a fleet of 126 aircraft (8 707, 30 DC-6, 44 Noratlas, 44 Vickers Viscount) and added a fifth fleet type (Sud Caravalle)

My commonality factors increased by 36% for each fleet type.  When you look at the sub-components, the admin component increased by 45% for the 707, DC-6, and Vickers.  The admin increased by 53% for the Nord.  For the fixed and crew training, all four types increased by 35.4%.

If you want more detailed info (I have the complete breakout saved), I can PM you, but didn't think it was noteworthy enough to post given the results above.

More data:

In JA#5, I had a fleet of 166 aircraft (15 707, 39 DC-6, 31 Noratlas, 67 Vickers Viscount and 14 Caravalle)

I terminated my lease on 1 Noratlas.  My commonality for crew and fixed expense decreased by 0.75% (75 bps) on each of the other fleet types.  The commonlity for admin decreased by 0.65% (65 bps) on each of the other fleet types.  Based on casual observation, this relationship goes both directions.

<edit> I received a new aircraft.  My commonality values reverted back to the pre-Noratlas lease termination levels.

I've got a lot of numbers to put in, too. Been c&p-ing them to notepad, but been a bit busy and haven't got around to looking at them.

3 to 4 fleet jump is definitely still exponentially increasing, your newest numbers show that, too.

[dmoose42]

It seems that it's a combination of the 3-4 fleet jump, but also the fact that each additional aircraft imposes a penalty on all other planes.  When your airline is small (<100 planes), the benefit from the additional plane reduces maintenance by more than the increase from the penalty across all planes.  After about 100, this trend reverses itself.  This is in addition to the incremental fleet penalties.

[Sanabas]

each additional aircraft imposes a penalty on all other planes.

That's a direct consequence of the exponentially increasing penalty for the 4th fleet.

If your 67 Viscounts have a base cost of 100% with 3 fleets, cost 180% with 4 fleets & 165 planes, 181% with 4 fleets & 166 planes, 200% with 4 fleets & 200 planes, then adding the 166th plane would see your other fleets all jump 0.56%. Adding 35 non-Viscounts would mean the Viscount fleet costs would jump 11.1%.

[dmoose42]

Added another fleet type (now have 6) and got about 22% increase in admin, and 27% increase in fixed/crew.
