    Divagating briefly, I note that a flight management system fitted to
    some aircraft (Rockwell-Collins FMS800)  allows one to select
    a prospective change of heading in a smooth turn onto a new
    course when approaching a waypoint,
    or a change only at the waypoint (or no change at all....)
