DEAD RECKONING

While in Enroute or Oceanic phase of flight, if the system detects an invalid GPS
solution or is unable to calculate a GPS position, the system automatically reverts to
Dead Reckoning (DR) Mode. In DR Mode, the system uses its last-known position
combined with continuously updated airspeed and heading data (when available) to
calculate and display the aircraft' s current estimated position.
