🔍 Key Concepts

• Cross bearings for a position fix • Why bearings that are close to 90° apart are most accurate • Effect of acute vs. obtuse angles between lines of position (LOPs) on fix quality

💭 Think About

• Compare the angle between 086° and each answer choice— which option gives a line of position that is closest to a right angle (about 90°)? • Think about how the intersection angle between two bearings affects the size of the "cocked hat" and the reliability of the fix. • Which bearing choice avoids being nearly in line with 086° (too small angle) or almost directly opposite 086° (too close to 180°)?

✅ Before You Answer

• Calculate the difference in degrees between 086° and each option, always using the smaller angle between them (0–180°). • Look for the option whose angle from 086° is closest to 90°. • Eliminate any choices that create very small angles (nearly parallel LOPs) or angles very close to 180° (back bearings).
