Question 1 of 27070

Your GPS position is LAT 41°10.0'N, LONG 72°52.5'W. What is the course per standard magnetic compass to a position one mile due south of Falkner Island Light?

🔍 Key Concepts

• Latitude and longitude plotting on the chart to find both positions • Finding a true course between two points, then applying variation and deviation to get compass course • Understanding what “per standard magnetic compass (psc)” means

💭 Think About

• Where is Falkner Island Light on your chart, and how do you find the point one mile due south of it using latitude scale? • Once you have both positions plotted, how do you measure the true course from your GPS position to that point, and in which direction do you read it? • How do you convert true course to standard compass course using the local variation and the deviation for the heading you’ll be steering?

✅ Before You Answer

• Confirm you plotted both positions correctly, especially “one mile due south” using the latitude scale (1’ of latitude = 1 NM). • Verify you used the correct magnetic variation for the chart and applied it in the correct direction (True ± Variation = Magnetic). • Check the deviation for the nearest heading on the deviation table and make sure you applied it correctly to go from magnetic to compass (Magnetic ± Deviation = Compass).
