Show the answer
Correct answer: c) 0900
Why it is correct
Longitude 015º 34.8′ W exceeds 7º 30′ W and falls in zone +1 W (between 7º 30′ W and 22º 30′ W). Adding 1 hour to 0800 gives HcG = 0900.
Why the others are not
- a) Subtracts 1 hour as if the longitude were east.
- b) Uses zone 0 like Canary Islands official time instead of nautical zone +1 W.
- d) Adds 2 hours as if west of 22º 30′ W.
How to work it out in the exam
- At longitude 015º 34.8′ W the nautical zone is +1 W: HcG = Hz + 1h.
