A circle of latitude at latitude lat =1.3963 rad has the radius R s = R · cos(lat) = 1106 km, so d =1000 km now corresponds to an angular radius of r s = d / R s = d /(R · cos(lat)) = 0.9039. Hence, covering d =1000 km on a circle of latitude gets you to longitude lon S = lon ± d /(R · cos(lat)) = -0.6981 rad ± 0.9039 rad. The equator is zero degrees latitude.
