Automatic landing on Quadplane

Hi there,

I would like to ask you some questions regarding the automatic land with the RTL command on a Quadplane. I saw that there are different ways to program the RTL action with Q_RTL_MODE parameter.
I saw the documentation on Q_RTL_MODE = 1, 2 or 3 (QuadPlane AUTO Missions — Plane documentation) but I don’t understand the real difference between them. Do you have any precise explanations ?

Is there any mode which automatically faces the wind ?

Which mode is the most secured ?

Thank you
