🔍 Key Concepts

• Using a known range (two charted objects in line) to find true bearing • Applying variation to convert between true and magnetic bearings • Using the sequence Compass – Deviation – Magnetic – Variation – True (CDMVT) and the rule "Add East"

💭 Think About

• From the chart, determine the true bearing of the line between Stratford Pt. Light and Igor I. Sikorsky Airport Aero Beacon. How does that compare to your compass bearing? • Once you know variation in that area, how do you get from true to magnetic, and then compare magnetic to compass to find deviation? • When the compass reads higher or lower than magnetic, does that indicate east or west deviation?

✅ Before You Answer

• Verify the charted true bearing of the range Stratford Pt. Light – Sikorsky Aero Beacon • Confirm the local magnetic variation and whether it is east or west • Carefully apply the CDMVT relationship and the rule "Add East" to decide the sign (E or W) and size (in degrees) of the deviation
