Cessna 172 mod

Hello everyone,

I hope you are as excited as I am when I hear a title like this one
Over the weekend I've been busy and made the my first modification for the Aerofly FS 2 Flight Simulator: a cold and dark capable Cessna 172 mod.

Not only can it do engine start/stop, you can also set the master battery, alternator and avions to off and enjoy a dark cockpit. Plus you can turn off individual panels like the COM1, NAV1 panel.
I also included a lot of small gimmics like opening doors and windows (they create drag when opened in the air) and also moveable sunshades. Almost all instruments in the cockpit are now working, including fuel flow and egt and so on. Their indications are faked at the moment but I am sure you could improve them a lot if you put in more time and effort. I was really impressed that all these things are possible in the Aerofly FS 2 and it wasn't any harder than I was used to from the previous Aerofly simulators.

This mod only requires the Aerofly FS 2 Flight Simulator Steam edition to run and I will try to update this Cessna mod for future version that will come.

I hope you will have a lot of fun with this mod, here is your download link from my personal website:

[...] seems mixture stab and most controls work with scroll wheel and not with mouse click?[...]

Why would you want to click the mixture? Click and drag maybe but that is not yet implemented in Aerofly FS 2.

The mouse control in the cockpit cannot be changed by the aircraft files. IPACS will need to change that, its out of the range of outside developers.

Quote from jcomm

Does mixture actually work requiring leaning with altitude?

As mentioned on the download page: no.

- Is it possible to, either through config file editing or SDK, modify temperatures, pressures, cloud cover, time of day / date?

Time of day has a slider in the simulator settings and a key assignment ("T" and "Shift+T").
Clouds are currently cirrus and cumulus, you can set their densities...

Temperature is standard ISA, I've not seen any setting for that yet in any config file. Same with pressure.

Quote from jcomm

And, regarding temperature and pressure, does Aerofly model density altitude?

I never got why people want to use density altitude. When I have the density for given temperature and pressure, why do I need anything else? Its like saying the airplane stalls because its too slow when the real issue is an angle of attack that is too big...

Air density, pressure and temperature in the Aerofly reduce with altitude.

- I believe in the present version there is no fuel consumption, but I wonder if the necessary hooks are available for more detailed modeling of fuel systems, starting with basic fuel consumption, and affecting weight & ballance ?

That is such an important feature, its just a matter of time. Currently you could accumulate the fuel used by the engine and kill it at some point, you could shift the center of gravity but you can't make the airplane lighter yet (except dropping a finite mass).

Hello Michael,

Switching the master off should theoretically not stop the engine I think.
Turning off the magnetos should however and it did that last time I checked...
Edit: I just checked it again with the current beta version of Aerofly FS 2. My engine stopps when I turn the magnetos all the way to off (using mousewheel)

Cheers,
Jan

Hey everyone,

version 2 of this mod is now available:
http://www.aerofly-sim.de/down…oflyfs2/af2_c172_download

Changes since last version of this mod:
- used fuel simulation and electical system of the latest Aerofly FS 2 Simulator to its fullest, a lot of code could be simplified because the simulation is now taking care of most of the logic needed.
- redid the engine starting with more modern techniques that became available with the last version
- added multiple ways to change the state of switches (left and rightclick as well as scroll wheel)
- fuel empty should now kill the engine
- gyro compass adjust added
- improved the starter key auto-return to both magnetos
- added parking brake

Of course you can disable the map somehow. If you turn off both master avionic switches that should make the display go off, so you just have to tell the display never to turn on in the .tmd code of the c172. In my modified C172 you can just comment out the lines 3339 to 3341 which should look like this:

<[string8][object][output]
            <[string8][Input][DisplayBrightness.Output]>
        >

if you change that to

//        <[string8][object][output]
//            <[string8][Input][DisplayBrightness.Output]>
//        >

the display on the right should be off.

Interesting because I did not change the switches around as far as I remember. Are you using the latest Beta of the Aerofly FS 2?
The only thing that I added again to the default version is the ability to turn off the engine.

Which switches are not working anymore for you?
I don't have a Saitek Panel on my desk to check it myself...

Well radios should go dark at some point. If you just leave the engine at low power the generator won't produce enough electricity to maintain the current flowing to all consumers. So the battery voltage slowly decreases until its empty. Then the devices run out of juice and turn off one after the other...
