POSITION ACCURACY
The following data related to Position Accuracy are displayed on the
PROG page:
GPS Status [5R]

For non GPS A/C this filed is blank.
When both GPS accuracy and integrity
requirements are met, the Confidence

or GPIRS (hybrid system) position is
designated as GPS PRIMARY, displayed

When GPS/IRS mode is restored "GPS PRIMARY" message (white) is
triggered on MCDU and on ND; GPS PRIMARY is again displayed in
