135. A GPS course-deviation bar and dots indicate what, and what determines full-scale deflection?
Answer
Absolute NM error; scale depends on mode
Explanation
The display represents cross-track error as a lateral distance, commonly in NM. Its sensitivity or full-scale deflection depends on the selected operating mode. **Key takeaway:** GPS CDI sensitivity is mode-dependent. **Glossary:** Cross-track error: lateral distance from the desired route.
