288 - ATPL Question Bank in English - Which of the following is an advantage of a multi-sensor system using GNSS and inertial-reference inputs?

Question 288 - Radio Navigation - ATPL - Airline Transport Pilot Licence

GNSS is never used as an input in a multi-sensor system.

The FMS always uses average position calculated from the GNSS and the IRS.

A GNSS update permanently removes all inertial sensor errors, even after GNSS reception is lost.

The GNSS can be used to update the FMS position from a drifting IRS.
