The coning angle of the rotor blades is the angle between

  • the horizontal and the rotor blades.
  • the rotor blades and the tip path plane.
  • the normal axis and the rotor blades.

Explanation from PART66Online

The coning angle is the angle between the rotor blade (its spanwise axis) and the tip-path plane, formed as lift bends the blades upward about the flapping hinge. It increases with higher lift or lower rotor RPM. It is measured relative to the tip-path plane, not the horizon directly.
