QGC Mission planning for air-launched UAV

QGroundControl

Hello,

I am developing a UAV (fixed-wing) that is launched mid-air by another platform. QGC is used to run simulations for it.

  1. How can I initialize the home location at an arbitrary altitude for mission planning?
  2. What is the arming procedure for the same i.e. for a platform being launched mid-air?

Thanks in advance.
