sensors in bearing/distance format from the Master FMC position. This page
provides the capability to remove specific sensors from the FMC navigation
solution.
Push – alternately selects SENSOR SELECT ON (enabled) and OFF (disabled).
ON (large green font) – caret prompts are displayed on each sensor line that can
be controlled:
• line selecting a sensor toggles it on or off
• the system prevents both of the IRU sensors or both of the GPS sensors
from being selected OFF simultaneously
• when a sensor is selected OFF, the data line and header are displayed in
small font cyan with (OFF) in the header
• selecting a sensor OFF does not disable or remove power from the sensor,
it simply prevents the FMC from using its output for the navigation
solution
