Eventide ARGUS 5000 - Page 135

you can't have selected EXTERNAL NAVIGATION because the Argus has no self-
directed destination in that mode.
DEMO mode is annunciated by the word DEMO appearing in reverse video at the top
center of the screen, replacing the TK or HDG normally present when actually
navigating. You exit the DEMO mode by returning to the simulated flight page and
selecting STOP. As a safety feature, the Argus will also drop out of DEMO mode
whenever data is received from a navigation receiver. Thus, if you have wired both the
Argus and your GPS together for home use, you will have to turn the GPS off or
otherwise inhibit its data output when using the Argus in DEMO mode. Of course,
if the GPS has a demo mode as well, you can use the units together as they would be
used in the aircraft.
AMEND SELECTIONS IN EMERGENCY MODE
In EMERgency mode, only RUNWAY LENGTH, SURFACE, and lighting selections
are honored (except for ASPH/CONC and TURF, which will always be admitted
whether selected or not). Heliports will not be displayed unless Rotary Wing is
selected in SETUP for aircraft type. Airports are displayed regardless of fuel
availability or ownership/use status, on the theory that in an emergency you're less
worried about getting fuel than about getting down!
