case the S-D/A-D readouts and VOR and designator
symbols disappear and the WPT CRS bearing
numerals change to DMEH.
(4) Checklist. The rotary switch on the
Control Unit has four checklist positions, INDEX and
LIST positions for both emergency ( EMER) and
normal (NORM) operations. With the switch in either
INDEX position, the indicator displays the appropriate
index of procedures contained in the memories. The
PAGE and LINE advance, SKIP and RCL momentary
push-button switches are used in conjunction with the
checklist displays. The PAGE switch allows the
operator to advance from one page to the next in an
index or list. The LINE switch allows the operator to
advance from one procedure to another in an index, or
from one item to another in a list. The SKIP switch
allows the operator to bypass, or not check, any item
in a list. The recall (RCL) switch allows the operator to
return to the first page and item not checked, or
skipped, remains. The following terms define the
elements of the checklist displays.
(a) Checklist. A checklist is a collection
of sequential procedures to be followed by a pilot.
There are two checklists: one for normal procedures
and one for emergency procedures.
(b) Procedure. A procedure consists of
one or more related items that are checked in
sequence by the pilot.
(c) Item. An item is a specific action
taken or condition checked by the pilot. An item may
be displayed on one or more lines.
(d) Index. An index consists of a list of
all procedures by title, with each title numbered
sequentially. There are two indexes: one for normal
procedures and one for emergency procedures.
(e) Cursor. The cursor consists of
changing the color of a selected procedure or item
being checked in a list. The cursor turns the letters
yellow in the NORM INDEX or NORM LIST and red in
the EMER INDEX or EMER LIST. Unselected
procedures in an index or unchecked items in a list are
green. Items already checked in a list are blue.
