🔍 Key Concepts

• How the angle between two lines of position (LOPs) affects the accuracy of a fix • Why a fix is strongest when LOPs are close to 90° apart • Difference between nearly parallel bearings and nearly perpendicular bearings

💭 Think About

• First, sketch the 176° bearing to the lighthouse. From your position, in what general direction is that line of position running? • For each choice, think about the angle between 176° and that bearing. Which option gives a line that is closest to perpendicular to 176°? • Which choice would produce a very shallow crossing angle (not good) and which would produce a sharp crossing angle (good for an accurate fix)?

✅ Before You Answer

• Compute or estimate the difference in degrees between 176° and each option (remember bearings wrap around 360°). • Identify which option gives an angle closest to 90° from 176°. That bearing will give the best fix. • Eliminate any bearings that are too close to 176° (nearly parallel) or almost opposite (around 180°), as these give poor fixes.
