approaches may be flown using the active flight plan
guidance. They may not be inserted into an alternate
flight plan.
(3) To select an FMS approach for use in the
active flight plan, press the EDIT function key on the
CDU and then select FMS APPR line key to access
the FMS APPR selection page. Refer to Figure 3C-84
and Table 3C-63. The three types of FMS approaches
that may be selected are GPS, Visual, or Tactical. To
select either a published GPS or runway visual
approach, enter the Destination (DEST) airport
identifier at the top of the page (also entered on the
working copy STAR definition). This calls up a listing
of available GPS approaches and runways for that
the
airport. To select a user defined tactical approach, no
airport identifier is required, select the TACTICAL line
key.
Two different FMS approaches can be selected
and maintained by the FMS–800. One is inserted into
the active flight plan and the other is referred to as the
working copy. The current approach definition being
displayed is indicated by the data on the information
line of the FMS Approach page and by asterisks and
larger arrows displayed adjacent to the selected
approach.
Large arrows indicate that the item has
been selected for insertion (working copy). Asterisks
indicate that the item is currently included in the active
