Floating plane

Recommended Posts

Good morning.

I have downloaded a Boeing 787-8 from CamSim, in this site. When I try to fly, the plane is floating about 2/3 feet from ground. How can I solve this?

Thanks in advance your kind answer.

Sorry. As long as my FS9 as I do not have FSX, in which forum do I have to post it?

Thanks

I have requested ADMIN to move your topic to the FS2004 forum!

 

Magic happens!

jmie,

 

Could you please quote the exact file name of your "floating" B787-8 aircraft, so that I can download it myself in order to test your problem and to possibly solve it for you.

 

I hope it's not payware though.

 

Regards

It is a CamSim file downloaded from this site. I have downloaded several CamSim Boeing 787-8 and put them together in a single file. Thus it 's happens in all aircraft (about 10). The only thing I have added is the new planes in the  "aircraft.cfg" file, maintaining the correspondent sequential number. No other modification has been made in such file, which in my opinion is "the responsible" of such floating aircraft. Maybe it's something in the geometrical  or so.

Thanks

So, you are using one aircraft.cfg for your multiple aircraft and they all float above the ground?  Sounds like a [Contact Point] problem.

Do you remember which Camsim 787 was the first one?  That would be the one to download and check out.

That is the content of [Contact Point]:

[contact_points]
static_pitch = -1
static_cg_height = 19.0275
tailwheel_lock = 0
gear_system_type = 1
max_number_of_points = 28

Contact points should look something like this:

 

       //0  Class                        <0=none,1=wheel, 2=scrape, 3=float>
        //1  Longitudinal Position        (feet)
        //2  Lateral Position             (feet)
        //3  Vertical Position            (feet)
        //4  Impact Damage Threshold      (Feet Per Minute)
        //5  Brake Map                    (0=None, 1=Left, 2=Right)
        //6  Wheel Radius                 (feet)
        //7  Steer Angle                  (degrees)
        //8  Static Compression           (feet)  (0 if rigid)
        //9  Max/Static Compression Ratio
        //10 Damping Ratio                (0=Undamped, 1=Critically Damped)
        //11 Extension Time               (seconds)
        //12 Retraction Time              (seconds)
        //13 Sound Type
        //14 Airspeed limit for retraction     (KIAS)
        //15 Airspeed that gear gets damage at (KIAS)

jmie,

 

What I need to be able to help you is the name of your complete and originally downloaded B787-8 file, which contains it's dedicated model folder, air file, at least one complete texture folder and it's complete dedicated aircraft.cfg file
I need to be able to see in external view, the aircraft standing on it's wheels (or floating), while at the same time having the same aircraft's aircraft.cfg file visibly available. Only then can I edit the contact point section in order to stop it from "floating" or sinking into the ground, etc. This is because it remains a so called "trial and error" activity and is not the same for, e.g. B787-8s with different model/texture files.

 

Regards

 

Hans

It looks like down. What I did is to modify as your suggestion. But remaining the rest of contact points from 6 to 21 as they are. if I delete such contact points the image enclosed remains equal. I suppose that contact points from 6 to 21 must be also modify. Don't you?

Thanks

Only the first three lines concern you here, leave the others untouched.
 

In the example given, you need to adjust the vertical position, e.g.:
point.0= 1.000, 82.930, 0.000, -9.350, 1181.102, 0.000, 3.349, 78.000, 0.500, 2.500, 0.500, 15.000, 15.000, 0.000, 0.000, 0.000
point.1= 1.000, -3.341, -12.000, -11.383, 1574.803, 1.000, 2.188, 0.000, 1.072, 2.500, 0.498, 17.000, 17.000, 2.000, 0.000, 0.000
point.2= 1.000, -3.341, 12.000, -11.383, 1574.803, 2.000, 2.188, 0.000, 1.072, 2.500, 0.498, 17.000, 17.000, 3.000, 0.000, 0.000

 

These will be different for every aircraft, those figures are the distance between the defined centre-line of the aircraft and the ground. It sounds like you need to reduce the figures in your aircraft (not this example!) by a couple of feet - start there and fine tune. Re-load the aircraft after saving each change.

 

Only when you have that perfect, you may need to finely adjust the following:
static_pitch = 
static_cg_height = 

 

Getting this right takes patience, but the results are satisfying.

Sorry, I just got back from Mars and I may have missed some critical detail, but if I might put in my two cents worth....

Have you tried Aircraft Container Manger? This free program allows one to see what could be going wrong with your

aircraft and correct things like contact points, without a whole lot of guesswork. It sounds like this could be of benefit to you.

It is available here -simviation.com/1/search?submit=1&keywords=aircraft+container+manager&x=17&y=7

You give me the idea. It is clear that it's a question of trial and error.

Changing the static_cg_height from the original 9.862 to 18.862 rise the aircraft to the position it must be. Enclose picture.

Thanks you all for your kind advise and cooperation.

Hello JMIE, by looking at the image you posted, it seems like your nose gear is still a bit off the ground. You can use ACM to locate each tire precisely on the tarmac. On that particular aircraft, you

should have only 10 contact points, one for each tire, unless the extra points are crash damage on the engines. wing tips or fuselage. In that case, they should be renamed "scrape"points in ACM. With a little patience you should be able to get your flying machine straightened out in no time!

From the screenshot above , seems just moved above and all the gears are fully extended.
I think better read the SDK and understand which number has what meanings.

Thanks you all. It's true, by reducing another point in the static_cg_height, the nose gear seems on the ground.

I really appreciate your comments and suggestions.

Have a nice day and "flight"
