b. The FMS must receive valid SBAS signals
c. The NAV mode must be previously engaged
I think b. is the problem. Have you got GAGAN enabled in System-GPS Status-SBAS?
Hi.
Yes. In fact we were on SBAS (GAGAN) navigation on arrival route using NAV mode. Approach was loaded and activated via IAF. There wasn't a caution or message flagged during the entire procedure.
Thanks anyway
