🔍 Key Concepts

• Lines of position (LOPs) and how they cross to form a good fix • Why a 90° angle between two bearings usually gives the most accurate position • How to find the angular difference between two true bearings

💭 Think About

• First, find the difference in degrees between the 356° bearing and each of the answer choices. Are you measuring the smallest angle between them? • Think about which angular separation between two LOPs (very small, very large, around 90°) gives the tightest, most reliable fix. • Which choice gives a crossing angle that is closest to a right angle, rather than nearly in line or only slightly different?

✅ Before You Answer

• Compute the smallest angular difference (0°–180°) between 356° and each option before deciding. • Eliminate any option where the bearings are almost opposite (around 180° apart) or almost the same (very small difference). • Select the option whose difference from 356° is closest to 90° for the best fix geometry.
