Final answer:
The Localizer will show full deflection until within 2.5 to 5 degrees of the runway approach course in aviation navigation systems.
Step-by-step explanation:
The question seems to be related to navigation, specifically referencing the Localizer (LOC), which is part of an Instrument Landing System (ILS) used in aviation to help pilots align with the runway during their approach. The complete answer to the question would be: "The LOC will show full deflection until you get within 2.5 to 5 degrees of the course." Aircraft navigation systems will show max deflection when outside this range, as the signal is not yet precise enough to provide reliable guidance towards the runway centerline.
