LOSS OF GPS (DEAD RECKONING)
Failure Indication:
A “Dead Reckoning” yellow CAS Caution message is issued and
the map will display “Dead Reckoning” along the top left edge of
the map.
Functionality Lost:
Following loss of GPS navigation, Dead Reckoning (DR) provides
limited navigation capability for up to 5 minutes. The AeroNav will
use speed and last known position at the time of GPS loss along
with any heading data it may have to provide an estimate of
aircraft position. At the end of that 5 minute period, if GPS lock
has not been reacquired, the system will transition to No GPS
and provide the appropriate CAS message and remove the
ownship symbol from the moving map.
All GPS-based navigation should remain unaffected during DR
mode, albeit with less accuracy and LPV approaches will be
terminated due to loss of integrity so higher minimums for the less
accurate GPS-based approaches will need to be used.
Some safety and alerting functions will be lost if GPS is
unavailable inc
luding TAWS, FLTA, and 500’ callouts.
Recommended Pilot Action:
In the event of a GPS position fix loss, the pilot’s plan of action
will vary based on the pilot, aircraft configuration, phase of flight
and other factors. Taking into account those variations, pilots
should consider the following actions:

Establish safe separation from terrain, traffic and
hazardous weather, using ATC assistance as necessary

If the affected AeroNav is in use for primary nav or com
†
,
transition to secondary GPS or VHF Nav/Com unit(s), if
available
