ARRIVAL AT AN ENROUTE WAYPOINT
To set the radius for the
Arrival Alarm you should
refer to the data on
Screen 23, NAV Mode
Customization Screen.
When the distance
remaining to run to an
enroute waypoint falls
below the Arrival Alarm
value, the [WPT ALERT]
flag is displayed and the
internal and external
alarms (if switched on)
beep at a rate of 2Hz for
5 seconds. To make the
change to NEXT LEG you
have to press Key 1 and if
you wish to silence the
alarm before the 5 seconds are up, simply press Key 5, the label of
which has meantime changed to ALARM OFF. When the alarm is
switched off automatically after 5 seconds, Key 5 will go blank and have
no function for 2 seconds then revert to DIRECT TO. This is a safety
measure to prevent you from inadvertently selecting DIRECT TO mode
by pressing the key just as it is canceling automatically.
Once you have pressed Key 1 to select the next leg, Screen 47 re-
appears showing all the relevant information for the new leg. The next
leg of the flight plan will now be displayed as a solid line.
If you pass the WPT, the flag will change to [WPT PASSED]. If the unit
has been set up for AUTO NEXT LEG in Screen 23, then as the WPT is
passed the unit will automatically revert to Screen 47 with all the new leg
information. Key 1 will go blank and inactive for two seconds then revert
to MAIN MENU.
When the WPT ALERT alarm has been given, a new box will appear at
the bottom of the screen showing the new course [SET NEW CRS XXX]
to steer for the next leg of the flight plan. The next leg of the flight plan
will also be displayed as a dotted line.
Prior to reaching a waypoint within a flight plan, Turn Anticipation pro-
vides navigation along a curved path segment to ensure a smooth transi-
tion between two adjacent legs in the flight plan. The curved path seg-
ment is based upon the aircraft's ground speed and the amount of
course angle change between the legs.
Turn Anticipation will only work if it is selected ON in Screen 23, NAV
Mode Customization Screen, and if the course change is greater than 5°
