• places the airplane on the center of the destination airport
• displayed cyan if no destination airport is entered in the flight plan.
CURSOR (toggle on/off) –
• when activated, recenters airplane on the position where the cursor clicks
• cursor changes shape when mode is active
• deactivated when any of the other centering keys are selected, the center
on CURSOR key is re-selected, or the cursor leaves the ND.
CTR ON – – – – (momentary push) – centers on any database item (STA, WPT,
APT) or latitude/longitude coordinate already entered in the scratchpad
Allows the pilot to graphically create a latitude/longitude point or select a visible
waypoint, airport, or navigation aid.
• visible when the cursor is on the ND map area
• enabled when the scratchpad is empty
• disabled when the scratchpad contains data
• when activated, the PICK WPT key label changes to CANCEL.
