Sorting aircraft in the "Installed aircraft" section

Postby Flyingfootball » Wed Jun 26, 2019 9:59 am

Hi! I'm new to this forum and to flightgear as well, and had a few issues I wanted to seek help for.

The absolute first is that the interface sorts planes from outside the default hangar (that I download) differently.

While for example the default Cessna 172P has a dropdown list that lets you change your variant to say, Amphibious, Bush tires, skis, etc, Other aircraft do not.

This means that I have one entry for the ATR 72-500, and another one for the cargo variant of the same aircraft.

This ultimately means that if I download the A320 family by Omega, I will have literally 4-5 entries, imstead of just one, making going through the list a little more difficult.

Is there a fix for this?

My version: 2018.3.2 on Windows 10
OS- Windows 10.
GPU- Nvidia Geforce 920M

PS- For those interested, here is the ATR-72 I'm using, It seems nice so far:

the fix for your problem lies with the craft maintainers... it is they that create the -set.xml files and they that can combine or separate them...

The aircraft I have are not maintained, being from the omega hangar which seems to have closed down. Is there some script or editting I could use to do this myself?

nope... not unless you want to start maintaining those craft and updating them to the new launcher capabilities...

I meant; Not even for my own use in my own computer, there absolutely aren't guidelines to editting them for this?

You should only see 2 aircrafts
A320-200-IAE and A320neo-PW.

The A320-100-CFM and A320-200-CFM are variants of A320-200-IAE.
And the A320neo-CFM is a variant of A320neo-PW.

If you have downloaded and installed manually, than this is a bug in FG version 2018.x.
I have the newer test version (2019.2) and the grouping works also on manually installed aircrafts.

Take a look at the c172p implementation.
Code: Select all
fgdata/Aircraft/c172p

You will find a file named c172-set.xml. This is the primary aircraft config file.
You will also find file c172-float-set.xml. This is the float variant. And c172-ski-set.xml is the ski variant.
Opening the file you will see that:
    It joins itself to the primary set via <PropertyList include="c172p-set.xml">
    it declares itself to be a variant of the c172p via <variant-of>c172p</variant-of>
If you use the c172 as a reference implementation, I image you will be successful in making the alterations you desire.

I tried this method, looked at the c172p as a reference and did the exact same thing to the ATR72 file, and its sorted it nice and tidy into one single aircraft with a cargo and pax variant.

Thanks! This is EXACTLY what I was looking to be able to do and exactly what I managed to do with your help.

Thanks and happy flying! :) :)

i'm glad it was easier than i thought... i remember when the c172p team worked hard to put all the variants into the one -set.xml so you could change the craft from in the sim by choosing options instead of having to exit the sim and select another variant... i recall wlbragg saying something about getting the templates working but i don't remember if that's completed or not... then there's this aspect of selecting which craft from the launcher which i thought was something to do with the templates stuff...

Yeah, the c172P has that going for it, the ability to change variants from within the sim. In my Dornier project if I ever get anywhere with it I'd be proud if I could do that, considering that aircraft has so many different functions its used for a passenger only variant doesn't really portray its versatility and wide area of operation.

I thought you were one of the devs in that project, that's a pretty cool username :)

Btw, about the 172P, is there a way to land it without veering off to the left or rolling onto the side and breaking the wings off?

i'm still learning the internals of FG so i'm just mainly a tester of the c172p on that team... i can wade into some things and figure out bits and pieces but i don't have a good handle on the flow and how all the parts actually fit together yet...

thanks on the username compliment... it was given to me some 30+ years ago by a group of girl friends i knew when i lived in virginia...

on landing the c172p, you have the same thing landing as taking off... p-factor... you have to learn how to adjust your ailerons to counter the roll and your rudder to counter the yaw... once you can handle that on takeoff, you should be able to do it on landing...

breaking the wheels and/or wings is coming down too hard... maybe you're flaring too high above the runway? but i can see the wings getting broken if you're rolling left and end up dragging the wing on the ground... there are or should be (maybe coming soon) aileron and rudder trim capabilities... i think the rudder one is bending a tab while outside at the rudder just like in real life... i'm not positive about aileron trim or where it would be made but i'm fairly sure i read some discussion about it...

talking about trim, i showed a friend FG and installed it on his laptop... it has a funky keyboard that needs cleaning or replacing badly... i loaned him a joystick and one of my spare keyboards... he/we can fly the UFO with no problem but the c172p keeps getting elevator trim signals from somewhere so it eventually ends up with the elevators all the way down and you can't pull any yoke to even try to get off the ground or get the nose up... haven't had time to figure that one out but once we do, i plan on getting him into the cessna to try closer to RL flying than the UFO can provide ;)

The 172 seems to also trim its aileron and rudder just a little bit prior to landing, especially if I use the Position aircraft in air menu, or for example the landing tutorial.

This is a lesser issue on the 182, so I usually just end up using that instead. I have seen others landing the plane and they always seem to come down and perform their landing roll? in a straight line, but I also notice their speed seems to be dropping as they come down. I retard the throttles upon touchdown rather than before.

I think I compensate with too much flare if I'm fast, hoping to use it to lose speed.
My earlier landings with the bird I'd not use flaps and land with slightly pitch low or straight, and it'd be fine. I wouldn't worry about my speed that much, but I'm trying to learn to land again and starting right from the aircraft I find the hardest to fly; The 172p.

I think what you said about takeoff is what I should practice next, so I'm taking of straight down the runway first.

Wow, that's kinda what happened to the 737 Max 8s... The Elevators it seems got trimmed downward by MCAS and lately some other part of the flight control computers....

I find that if it trims weirdly, I Can adjust the elevator trim with my scroll wheel, and for the aileron rudder I have no controls. Btw, is it possible that the rudder trim is making the wheels turn to one side, causing the plane to either tip over to its side (break the wings) or veer left? But so many GA planes do that, Including the Short Skyvan on FG.

for landing the c172, maybe this link will help? https://www.wikihow.com/Land-a-Cessna-172
step 2 seems to indicate that it is for a newer c172 but the most of that step and the following steps should be fine...

i found these other possibly helpful links, too...

There is no autotrim of any form on the Cessna - any such effects noticed could be due to ground effect but certainly not due to trim.

Thanks for the links!


In that case I suspect its a bug on the 172, because using the HUD I can see its the trim that's moved a little.
