DEAD RECKONING
While in Enroute or Oceanic phase of flight, if the Perspective
™
system detects an
invalid GPS solution or is unable to calculate a GPS position, the system automatically
reverts to DeadReckoning(DR)Mode.InDRMode,thesystemusesitslast-known
position combined with continuously updated airspeed and heading data (when
available) to calculate and display the aircraft’s current estimated position.
NOTE: Dead Reckoning Mode only functions in Enroute (ENR) or Oceanic
(OCN) phase of flight. In all other phases, an invalid GPS solution produces
a “NO GPS POSITION” annunciation on the map and the system stops
navigating in GPS Mode.
DRModeisindicatedbytheappearanceoftheletters‘DR’superimposedinyellow
over the ‘own aircraft’symbol as shown in the following gure. In addition, ‘DR’
is prominently displayed, also in yellow, on the HSI slightly above and to the right
of the aircraft symbol on the CDI as shown in the following figure. Also, the CDI
deviation bar is displayed in yellow. Lastly, but at the same time, a ‘GPS NAV LOST’
alert message appears on the PFD.
Normal navigation using GPS/SBAS source data resumes automatically once a valid
GPS solution is restored.
It is important to note that estimated navigation data supplied by the system in
DRModemaybecomeincreasinglyunreliableandmustnotbeusedasasolemeans
of navigation. If, while in DR Mode, airspeed and/or heading data is also lost or
notavailable,theDRfunctionmaynotbecapableofestimatingyourpositionand,
consequently, the system may display a path that is different than the actual movement
of the aircraft. Estimated position information displayed by the system through
DRwhilethereisnoheadingand/orairspeeddataavailableshouldnotbeusedfor
navigation.
DRModeisinherentlylessaccuratethanthestandardGPS/SBAS Mode due to the
lack of satellite measurements needed to determine a position. Changes in wind speed
and/or wind direction compounds the relative inaccuracy of DRMode.Becauseofthis
degraded accuracy, the crew must maintain position awareness using other navigation
equipment until GPS-derived position data is restored.
