Hey All,

Occasionally I see LOI appear in the HSI portion of my PFD.

Lotsa letters, huh?!

What does the LOI indication represent?

I searched the manual and came up with nothing.

LOST OF INTEGRITY

That occurs when your gps reception is none or poor.

LOI indication

The acronym is:

LOI = Loss Of (GPS) Integrity. It is in the pilots manual under HSI annunciation.
