A method and a system for engaging hovering flight for a rotary wing aircraft. A first mode of operation makes it possible, while the longitudinal speed UX of the aircraft is greater than a first threshold speed Vthresh1 to approach a stop position S while maintaining track relative to the ground, the flight setpoints of an autopilot being a ground course angle TKsol, a deceleration rate Ga for the forward speed Va of the aircraft, a flight path angle P, and a heading Ψ. A second mode of operation makes it possible, when the longitudinal speed UX is less than a second threshold speed Vthresh2, to engage hovering flight at the stop position S while maintaining heading, the flight setpoints being the longitudinal speed UX, a lateral speed VY, a vertical speed WZ, and the heading Ψ, the speeds UX, VY, and WZ being reduced progressively to zero speed.
