(a) NAV / GPS switch and annunciators - By depressing this switch, the
GNC300 data and the NAV (VOR/ILS) data will be alternately displayed on
the pilot’s HSI and selected for the autopilot / flight director input. The
source of data being displayed will be annunciated on the face of the unit with
either a white NAV legend or a green GPS legend as appropriate.
(b) GPS Message (MSG annunciator) - When the GNC300 has a new message,
the amber MSG annunciator will flash. When this occurs, press the MSG key
on the GNC300 to view the message. Continue to press the MSG key on the
GNC300 until the page you were viewing prior to pressing the MSG key is
displayed.
(c) GPS Waypoint (WPT annunciator) - When the GNC300 detects that the
aircraft is 15 seconds from the next programmed waypoint or turn
anticipation point, the amber WPT annunciator will flash and the CDI
depiction on the CDI Page will be replaced by a flashing "Next dtk xxx
°"
prompt. Approximately 2 seconds before the turn anticipation point
(calculated for 15 degrees of bank) the WPT annunciator will turn on steady.
This is the indication that you should start the turn to the next DTK. Upon
passing the waypoint (or half way through the turn), the annunciator will
automatically extinguish.
