  *State 1 (=ground_contact):

  *for GROUND_CONTACT_TRIGGER_TIME_US in order to detect ground_contact

  *State 2 (=maybe_landed):
  *maybe_landed can only occur if the internal ground_contact hysteresis state is true. maybe_landed criteria requires to have no motion in x and y,
- *no rotation and a thrust below 0.1 of the thrust_range (thrust_max - thrust_min). In addition, the mc_pos_control turns off the thrust_sp in
- *body frame along x and y. The criteria for maybe_landed needs to be true for MAYBE_LAND_DETECTOR_TRIGGER_TIME_US.

  *State 3 (=landed)
  *landed can only be detected if maybe_landed is true for LAND_DETECTOR_TRIGGER_TIME_US. No farther criteria is tested, but the mc_pos_control goes into

  *It is to note that if one criteria is not met, then vehicle exits the state directly without blocking.
