Derrota Loxodrómica. A Hrb=0600, en situación l=37º10’N y L=000º15’E, ponemos Rumbo verdadero Rv=240º con velocidad 12 nudos. - Calcular la situación a Hrb=0830Rhumb line. At ship’s clock 0600, at l=37º10’N and L=000º15’E, we set true course 240º at 12 knots. Calculate the position at 0830

Show the answer

Correct answer: c) l=36º 55.0’N - L=000º17.5’W

Why it is correct

d = 30. Δlat = 15′ S. Departure = 26′ W. ΔLong = 32.5′ W. It crosses Greenwich: 000º 15′ E − 32.5′ = 000º 17.5′ W.

Why the others are not

  • a) It does not match the working.
  • b) It does not match the working.
  • d) It does not match the working.

How to work it out in the exam

  1. Find the true course and distance.
  2. Δlat = d × cos R. Departure = d × sin R. ΔLong = departure / cos(mean latitude).
