Después de zarpar de Puerto Sherry, a hora de huso (Hz)= 200000, se encuentran en el WPT de salida (36º 32,5’N - 006º 19,2'W) y calculan la hcG (hora civil de Greenwich) en ese instante.After departing Puerto Sherry at zone time (Hz) = 200000 from the departure waypoint (36º 32.5’ N, 006º 19.2' W), calculate the Greenwich civil time (HcG) at that instant.
Show the answer
Correct answer: c) 200000
Why it is correct
Longitude 006º 19.2′ W is less than 7º 30′, so it lies in zone 0 (the Greenwich meridian). Zone time therefore equals Greenwich civil time: HcG = Hz = 200000.
Why the others are not
- a) Subtracts 2 hours, confusing nautical zone time with summer official time.
- b) Subtracts 1 hour, confusing geographical zone 0 with Spanish mainland official time.
- d) Adds 1 hour as if in zone +1 W.
How to work it out in the exam
- Between 7º 30′ E and 7º 30′ W the nautical zone is Z = 0, so HcG = Hz.
