AUTO NEXT LEG: on / off.
TURN ANTICIPATION: on / off
FLIGHT PLAN DISPLAY: all legs / active leg.
INTERNAL ALARM: on / off.
EXTERNAL ALARM: on / off.
CDI SCALE: This enables you to choose which of the given distances you want the unit to use as the
setting for the full-scale deflection of the Course Deviation Indicator (CDI) in NAV mode. This value is
always in nautical miles.
CDI DISPLAY: This allows you to set the CDI display in Map Mode to show either a bar graph, or a
numeric read-out of course deviation or to be switched off. If selected OFF, the CDI is no longer
shown while you are in Map Mode.
CDI ALARM: When selected ON this produces an audible alarm to tell you when full-scale deflection
of the CDI has been reached. If you choose to set this to OFF, you disable this alarm.
WPT ALERT: You can use this feature to set the distance away from your destination user waypoint
at which you wish the audio and visual arrival alarm to be activated. This value is always in nautical
miles.
AUTO LEG SELECT: If you select this ON, the unit will automatically place the cursor on the closest
leg when Screen 12, Flight Plan Program/Edit Screen, is accessed to select the flight plan. Although
the nearest leg to your present position is highlighted, an alternative leg may be selected by using the
joystick. If AUTO LEG SELECT is switched OFF the cursor will simply be positioned over the first leg
in the flight plan whenever Screen 12 is selected.
AUTO NEXT LEG: If you select this option ON then, as each user waypoint in the flight plan is
passed, the next leg will be automatically selected. You thus do not need to press Key 1 (the NEXT
LEG Key) as this function produces the same effect automatically. If you select AUTO NEXT LEG to
OFF, you will then need to activate the next leg in the flight plan manually by pressing Key 1 (the
NEXT LEG Key) at the end of each leg, otherwise your unit will continue to give you distance and
bearing information to your previous turning point.
TURN ANTICIPATION: Turn Anticipation provides navigation along a curved path segment to ensure a
smooth transition between two adjacent legs in the flight plan. If turned ON, Auto Next Leg will also
automatically turn on. Auto Next Leg is an essential part of turn anticipation. Please refer to Arrival at an
En-route User Waypoint in the Map Mode with NAV Information Screens Section of this Manual for more
details.
FLIGHT PLAN DISPLAY: Allows a choice of displaying the full flight plan or just the active leg on the
map screen.
INTERNAL (ARRIVAL and CDI) ALARM: This gives you the choice between having these internal
alarms functioning or inactive.
EXTERNAL (ARRIVAL and CDI) ALARM: This gives you the choice to switch ON or OFF the output
from the unit, which can drive an external alarm device.
