Para la realización de una travesía donde nuestra posición de salida estará definida por las coordenadas l= 44°05´N; L= 007°25´W y nuestra posición de llegada serán las coordenadas l= 43°45´N; L= 006° 30´W. Determinar el rumbo directo y distancia más aproximados para ir desde la posición de salida a la de llegada.For a passage from l= 44°05´N; L= 007°25´W to l= 43°45´N; L= 006° 30´W, find the closest direct course and distance.
Show the answer
Correct answer: a) R= 117° / Distance= 44.5 miles.
Why it is correct
Δlat = 20′ S. Departure = 55′ × cos 43º55′ = 39.6′ E. Course 117º, 44.4 miles.
Why the others are not
- b) It does not match the working.
- c) It does not match the working.
- d) It does not match the working.
How to work it out in the exam
- Find the difference of latitude and the departure: ΔL × cos(mean latitude).
- Course = arctan(A / Δlat). Distance = root of the sum of squares.
