Dev: Add guide for adding new flight mode in Plane

[dinesh286]

I want to add a new custom flight mode like autonomous landing for a fixed wing uav. All the tutorials are given for arducopter. Can any one help me to add a new custom flight mode for a fixed wing UAV in a arduplane

Adding a mode in Plane isn't easy. Your best bet for getting help is probably posting in the forum (http://discuss.ardupilot.org).

I've added a page with the Plane Architecture Overview which may help a bit. http://ardupilot.org/dev/docs/plane-architecture.html
