and

Director Guidance.
(1) Flight Instrument Displays. The FMS-800
provides lateral and vertical navigational situation
information to the pilot’s flight displays. The pilot’s
displays are driven using the navigational solutions
from the CDU Pilot Steering page, Paragraph
3C-25.e.(6)(a).
(2) Horizontal Situation Displays (HSI). In
order to display horizontal situational data on the
EHSI, the FMS source must be selected by the pilot.
The EHSI data includes the HSI course arrow (desired
track), TO / FROM pointer, and bearing pointer to the
FMS-800 outputs. These outputs always relate to the
flight plan active waypoint or pattern turn point. Refer
to Figure 3C-61. If the EHSI distance interface is
compatible and aircraft switching is installed, the
distance readout will also show great circle distance to
the active waypoint.
