· (Directto/
pattern/intercept) Key − Pushing the DIR function key inserts DIRECT,
PATTERN and INTERCEPT prompts on the ACTIVE FLT PLAN pages. If other than an
active flight plan page is displayed when pushing the button, the first page of the flight plan
is displayed. If the active flight plan is already displayed, it will remain on the current page of
the flight plan.
− DIRECT − The FMS DIRECTTO
function can either be lateral or vertical. The left line
select keys are used for lateral and the right line select keys are used for vertical
directto.
Lateral DIRECTTO
computes the turn and the course from the end of the
turn. If the directto
waypoint is in the flight plan, pushing the line select key next to the
directto
waypoint engages the directto.
A directto
course is calculated and the
airplane begins turning for the waypoint. Vertical DIRECTTO
is connected to an
altitude constraint at a waypoint in the flight plan. The altitude constraint must be in the
flight plan before the vertical directto
is done. Vertical DIRECTTO
can be used for
climbs and descents. The airplane does not respond to the vertical DIRECTTO
unless
the altitude selector is properly set above for climbs and below for descents.
