Power-Up Sequence
The power-up sequence is displayed every time the Apollo NMS is
turned on. The power-up sequence begins after the NMC completes an
approximately 2 second initialization of internal circuits. Following
initialization, the sequence will show the owner’s name, the database
version, the software version, present position, request for altimeter
correction factor, and the time/date. It also allows entry of a new
time/date and position during the sequence. The NMC will
automatically update the time from GPS satellite information at
power-up. If a valid datacard is not inserted, you will manually enter
the magnetic variation during the power-up sequence for the area you
will be flying in. In addition, the NMC displays start-up self-test pages,
self-test results, and asks if you want to continue with the last used
flight plan.
To acquire a position the system must “know” its approximate location
and, if using a GPS sensor, the time (UTC Coordinated Universal Time
formerly called Greenwich Mean Time).
Hint
The UTC and approximate position should be entered
by the installer; in which case, no action is normally
required of you during the power-up sequence. As
long as the system is functioning when you fly, the
NMS will always “know” its position the next time it
is powered up; however, if the NMC has been
removed from the panel for use in simulator mode,
your present position must be entered during
power-up after the unit is reinstalled in the aircraft.
Switching the power on starts the
power-up sequence.
