Question 34Navigation Problems70% to pass
You are steering 154° per gyrocompass. The wind is northeast by east, causing 4° leeway. The gyro error is 3° east, variation is 11° west, and deviation is 7°E. What is the true course made good?
AI Explanation
The correct answer is C) 161°T.
To arrive at this answer, we need to account for the various compass errors and leeway.
Given information:
- Steering 154° per gyrocompass
- Wind is northeast by east, causing 4° leeway
- Gyro error is 3° east
- Variation is 11° west
- Deviation is 7° east
To find the true course made good, we need to apply the following corrections:
Gyrocompass reading: 154°
Gyro error: +3° (east)
Variation: -11° (west)
Deviation: +7° (east)
Leeway: +4°
The true course made good is therefore 154° + 3° - 11° + 7° + 4° = 161°T.
The other options are incorrect because they do not properly account for the combination of the given compass errors and leeway.
