FSX Landing gear

[Billy wilbarts]

Hello I am new to FSdeveloper and i have been working on a Aircraft for FSX the model for while now i am on animation phase i just wanted to know how to make the landing gear like Airbus A340 or 777 have this is this done on animation or later on my first aircraft for FSX

Thank you

This will require a bit of custom XML coding and an animation trick.

Animate the gear assembly and then tag everything except for the bogey as "l_gear" or "r_gear", depending on the side you're working on. Do a tilting animation for the bogey (keyframe 0 = straight, keyframe 10 = tilted) and then tag it with a custom XML animation. The code could look like this:

<PartInfo>
   <Name>bogey_tilt</Name>
   <AnimLength>100</AnimLength>
   <Animation>
     <Parameter>
       <Code>
   (A:GEAR LEFT POSITION, percent) 95 &gt;
   (A:PLANE ALT ABOVE GROUND, feet) 10 &gt;
  and
   if{ 10 } els{ 0 }
       </Code>
     <Lag>10</Lag>
     </Parameter>
   </Animation>
</PartInfo>

This should make the bogeys go straight in 1 second (10 keyframes divided by 10 "lag" value) whenever the plane's reference datum (NOT landing gear!) is less than 10 feet above ground and the gear is extended by more than 95%. The extension condition ensures that the gear returns to its straight position for retraction (if it does on the real thing).

Ok Thanks for the reply i will try out and Let you know

This is a video of a 777 gear retraction and extension you will find useful

Fascinating, Roy! The gear retract a lot faster in the sim...

This completely destroys PMDG's credibility for me!

It's amazing to see just how much gravity can hinder and assist mechanical systems.

Thanks Roy For the video and yes animation phase in progress on my aircraft btw guys it not a 777 i am working on LOL btw thank you for the support and yeah i am starting to like fsdevloper =D
