If the course pointer is set to a wrong inbound course prior established or if the
pointer is moved away from a correct inbound course after established on the
localizer, the aircraft can or will deviate from the localizer.
SET CORRECT INBOUND COURSE.
WARNING
The lateral operation of this mode is essentially the same as in NAV LOC
mode except for higher FD/AP control law gains to give increased precision
during approach.
