Use local east, north and up axes. At latitude , and eastward velocity is . The Coriolis acceleration isIts horizontal part is southward, so the lift must acquire a northward component: bank left, with the north wing lower. For the requested local Coriolis correction, let the vertical lift balance . The Coriolis bank angle for eastward flight isUse and . Including the upward Coriolis term replaces by and changes the answer by only about . This is the horizontal Coriolis compensation, not a full calculation of a curved constant-latitude flight path. The rotation rate follows Earth's sidereal period.[ref]
