En situación de estima l: 36º 17`N L: 007º 16`W ponemos rumbo al punto P de coordenadas l: 36º 12`N L: 007º 24`W .Calcular analíticamente Rumbo directo y distancia navegada.At dead reckoning position l: 36º 17`N L: 007º 16`W we set course for point P at l: 36º 12`N L: 007º 24`W. Calculate analytically the direct course and distance run.
Show the answer
Correct answer: d) Rd: 232.2º D:8.1′
Why it is correct
Δlat = 5′ S. Departure = 8′ × cos 36º14′ = 6.5′ W. Course 232º. Distance about 8.2 miles.
Why the others are not
- a) It does not match the working.
- b) It does not match the working.
- c) 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.
