Adding C152 to FlightGear?

[randomizedcoder]

G'day,

Thanks for the great addition to FlightGear.

I'm having trouble adding the aircraft, so maybe I'm doing something silly?

My steps are:

1. git clone https://github.com/awall086/c152 into a folder.
2. Within FlightGear, go to Add-ons, Click "Add+", select the cloned folder.

Flightgear gives the error "No aircraft found in the folder '/home/das/Downloads/c152/AircraftConfig' - add anyway?"

I've looked at the instructions here: https://wiki.flightgear.org/Howto:Install_aircraft#Linux

Looking at the section "When installing an aircraft fails", it says to examine the -set.xml file:

[das@l:~/.fgfs/Aircraft/c152]$ cd ..

Looking at the file structures, I notice there is a "~/.fgfs/aircraft-data" folder, which contains some files about the c172, and some others I added (pitts for example). So I tried to add the c152.xml file in there.

[das@l:~/.fgfs/Aircraft]$ cd ..

But it didn't work.

Any suggestions appreciated.

I suppose it would be really nice to work out how to add the C152 to the FlighGear "Addcraft" "Browse" somehow.

Thanks in advance,
Dave

@awall086 I have no issue adding this aircraft to fgaddon so it will be able to be installed through FlightGear's QT GUI launcher. Just let me know if you want it in there. I think you could probably ask for access on the mailing list and be able to do it yourself and be able to update it periodically without having to ask someone else. I will vouch for you if needed.

[orbitalmartian8]

Hi Dave, if you select the folder that you cloned it into, so /home/das/Downloads/. This will add the aircraft into your FG aircraft list.

[randomizedcoder]

Thanks for the replies guys!

@wlbragg It would be pretty nice to be able to skip the git clone step. It's not a big step, but it would make it easier.

Thanks @orbitalmartian8

That worked!

[das@l:~/Downloads/c152/c152]$

This means my full path is:

/home/das/Downloads/c152/c152/

And adding the "Additional aircraft folders" WITHOUT including the last part of the path works:

/home/das/Downloads/c152

Note that is one less "/c152/"

And now it shows up!

Awesome! Thanks again!

It would be a great honor for me to have this plane included on FGAAddon's list, but I honestly wouldn't know where to start... If you could post it for me, or help me do so, I would be very grateful.

Thank you in advance :)

[awall086]

Thanks for the replies guys!

@wlbragg It would be pretty nice to be able to skip the git clone step. It's not a big step, but it would make it easier.

Thanks @orbitalmartian8

I'm glad to hear you were able to install the aircraft and it's now working properly. My thanks to @orbitalmartian8 and @wlbragg for their technical support.

[orbitalmartian8]

@awall086 I did a quick bit of research, looks somewhat straightforward to add to FGAddon.

Here's the wiki link I found: https://wiki.flightgear.org/FGAddon#Aircraft_development

[wlbragg]

@awall086 to verify, this is a c152 II and not a c152? If so, what do you think we should do, put the model into fgaddon under 152 and it will be known by its title that is is a c152-II variant of the c152 or put the model into fgaddon under c152-II?

FYI: both the c152 and the c152-II titles are available in fgaddon. There is no other c152 in the repository so we could technically use either. If you decide to change the folder name to c172-II we need to verify it doesn't mess up access to any files at runtime.

[awall086]

@wlbragg It's a 152 model. By mistake we inherit the label 152 II in the menu and in the about dialog, from the earlier time of development. I had reserching a bit and the diferences between 152 and 152 II is only cockpit equipment. (More equipmento to IFR flights capability in the 152 II)

I had remove from menu and about dialog references to C152 II. The repository is updated with this two little changes.

Thank you very much for your help. I tryed to understand the information in the wiki (Thanks to @orbitalmartian8) but is a little dificult for me without the sufficient knowledge in programming environments versionas and subversions.. :(

[wlbragg]

In order for you to be able to add it to fgaddon you would have to post a request to the mailing list. I encourage you to do that at some point. But I have no problem putting it in myself and will continue to forward any updated you might have periodically indefinitely or until you gain access yourself. I am going to go ahead and get it in there now.,

[wlbragg]

@awall086
I finished adding the 152 to fgaddons
https://sourceforge.net/p/flightgear/fgaddon/HEAD/tarball?path=/trunk/Aircraft/c152
Please pull a copy and verify I didn't miss anything. I had to push it in parts, it wouldn't let me upload the entire folder at one time.
I don't know how long it takes to populate to the launcher list. I think at least a few days to a week.

[awall086]

Hi @wlbragg Thank you very much for your help!!! A have my SorceForge Account, now. I had check the aircraft folder and is complete except in Liveries folder. The file LV-CMN.xml is missing. I´ll try to know how to upload this file to the folder.

All other files and folders are correct.

Thanks again for your effort.

[wlbragg]

The file LV-CMN.xml is missing.

Ok, let me know if you have any issues adding it. I don't know if you will have privileges to push to it without seeking it on the mailing list.

[wlbragg]

The file LV-CMN.xml is missing

@awall086 I still don't see that file in the fdaddon SVN repo, I also don't see it in my local repository. Where is that file supposed to be...
c152\Models\Liveries\LV_CMN.set
or
c152\Models\Liveries\LV_CMN\LV_CMN.xml

Were you able to add the missing file?

[awall086]

@wlbragg The file is in this repository:

I'll ask for permissions to upload files to FGAddon. I'm not sure if is possible to suggest to upload the c170 and the PA-38 to FGAddon too. I'll send an email to FG Devel mail list.
