Dear All,
This is the closest I could find to my question and somewhat helpful.
A320 'GPS PRIMARY LOST'
Could anyone explain the difference of
GPS Primary and
RAIM, I am aware there is a difference but not able to imagine it clearly. In addition, how does one perform the RAIM check for an RNAV (or similar) approach? Is RAIM the
Y Y Y Y seen in MCDU PROG page?
Thank you.
