Generally the standard lapse rate of temp with altitude is 2degrees celsius for every 1000ft, so whatever ground level temp is recorded, this formula is applied, however it is more complicated

http://en.wikipedia.org/wiki/Lapse_rate

In real world flying, 2degrees per 1000ft is considered standard and used in calcultions

Thanks.

Daidalos seems to not make this formula in IL-2 1946.

I remake temperature calculating in it.
and here today's version.

0m	-20C	-10C	14C	28C
1000m	-26.49C	-16.49C	7.51C	21.51C
2000m	-32.98C	-22.98C	1.02C	15.02C
3000m	-39.47C	-29.47C	-5.47C	8.53C
4000m	-45.96C	-35.96C	-11.96C	2.04C
5000m	-52.45C	-42.45C	-18.45C	-4.45C
6000m	-56.5C	-48.94C	-24.94C	-10.94C
7000m	-56.5C	-55.42999C	-31.42999C	-17.42999C
8000m	-56.5C	-56.5C	-37.92C	-23.92C
9000m	-56.5C	-56.5C	-44.41C	-30.41C
10000m	-56.5C	-56.5C	-50.89999C	-36.92C
11000m	-56.5C	-56.5C	-56.5C	-43.39C
12000m	-56.5C	-56.5C	-56.5C	-49.88C

Wow, i am impressed by this project... :O

I do have one question:
is there a specific reason you are stopping at "-56°C"?

Do you think it is possible to lmake temperature have an effect on the plane behavior?
cool air at high altitude = cool air in engine intake = cool air going in the radiator = new overheating algorythms?

Yes, reason is here...

International Standard Atmosphere
http://en.wikipedia.org/wiki/International_Standard_Atmosphere

At 15 degree Celcius in 0m hight,
ISA decreases temperature 6.5 degree per 1km high upto 11km.
From 11km to 20km , constant -56.5 degree Celcius.

When 0m height temperature is very low in Oceanic climate area...
this -56.5 degree Celcius air is lower down from 11000m.
I make this.

But I don't have enough data about arctic area winter temperature ratio.
I want more data to simulate any area on the Earth.

Do you think it is possible to lmake temperature have an effect on the plane behavior?
cool air at high altitude = cool air in engine intake = cool air going in the radiator = new overheating algorythms?

I'm touching only air temperature calculating.
Not overheating algorythms.
But overheating algorythms use air temperature calculating function, so my MOD affect overheating at the  last.

1    Tropopause    11.000    11.019    +0.0    ?56.5    22632
2    Stratosphere    20.000    20.063    +1.0    ?56.5         5474.9

indeed, i didnt notice that. sorry, my bad.
you are one step ahead of TD... respect!

This is very interesting work. Keep it up.

Great stuff, this could be very good!

BETA 0.04 for SASModAct without 1956 JetEra v1.2
and
BETA 0.04 for SASModAct with 1956 JetEra v1.2

are released in 1st page.


BETA 0.04 depends on based MOD envoronments.
SASModAct without 1956 JetEra v1.2 / SASModAct with 1956 JetEra v1.2 / DBW1.71 / HSFX5
every environment needs different "Variable Temperature MOD" zip.
I have made BETA 0.04 runnable classfiles for both DBW1.71 and HSFX5,
but I have to make MAPS folder's load.ini to work 0.04 well before MOD zip release.
DBW1.71 and HSFX5 have many additional MOD maps, I need more time to write new load.ini for MOD maps.


BETA 0.04 has a function writing out Temperatures in a mission to the log file, you can read it in the log file.
When you feel strange Temperature moving in some missions / some maps, please tell me with that log.

You list HSFX 5 above but not UP3.

I am assuming it does not work with UP3 with this version also right?

Thx.

UP3 prohibit this type MOD working.
Evenif install MOD classfiles in #UP# folder, UP3 ignores it.

REMOVED MY LAST POST

CTD solved because this mod share a classfiles with AI hotkeys 2.5 so need to be loaded before....

After this all is working fine and got good temperature curve in Balaton summer map with thermical 0° between 3000 and 4000 mt....

Great work!

All the best!

BETA 0.05 is released in 1st post.

I correct some maps' load.ini.

And I add DBW version with all DBW MOD maps' load.ini.

[xXxsliickxXx]

Hi, everybody! Dear western0221, correct the reference for DBW
