Joystick The function of the joystick depends upon the type of MFD display:
MAP or PLAN: Moves the designator in the directions shown.
TEXT: a. Vertical actuations - act as a cursor control by changing the active line.
This provides an additional means of skipping lines or returning to a
previously skipped line.

page number, and actuation to the left decreases the page number.

again selects North-up PLAN mode.
WX Weather radar data may be displayed with the MAP mode. The toggling
sequence of this button is: WX on WX off. If PLAN mode is selected, selection
of MAP mode will be forced when WX mode is selected.
VOR This button is used to display the four closest VORs, that are not on the active
flight plan list, on the MFD MAP and PLAN displays. The first push of the button
inserts the VORs with identifications. The second push removes the
identification, and the third push removes the VORs from the display.
APT The APT button is used to display the four closest airports, that are not on the
active flight plan list, to the MFD MAP and PLAN displays. The first push of the
APT button adds the airports with their identifiers. The next push of the button

lowest numbered uncompleted or unskipped checklist with the active line at that
