− INTEG (Integrity) - The GPS sensor does not meet the required
integrity calculations for the current phase of flight.
− WPT (Waypoint) - The airplane is approaching a flightplan
waypoint.
− DR (Dead reckoning) - The FMS is in dead reckoning mode.
− DGR (Degrade) - The ability of the FMS to accurately calculate
airplane position is degraded.
