Se pide calcular la situación observada por dos rectas de altura simultaneas en posición de estima: le=33°05,0´N; Le=061°27,7´W, sabiendo que se han observado los siguientes determinantes: Markab (Azimut verdadero =085º y Diferencia de altura =2,0 (-) y Dubhe (Azimut verdadero =330,5º y Diferencia de altura = 0,5 (-).Calculate the observed position from two simultaneous position lines at DR position le=33°05.0´N; Le=061°27.7´W, given: Markab (True azimuth =085º, Altitude difference =2.0 (-)) and Dubhe (True azimuth =330.5º, Altitude difference = 0.5 (-)).
Show the answer
Correct answer: c) 33°03.4´N 061°30.0´W
Why it is correct
Both differences are negative: we move away from both bodies. The crossing is at 33º 03.4′ N, 061º 30.0′ 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
- Draw each line at right angles to its azimuth, Δa miles from the DR position, towards the body if positive.
- The crossing gives the fix.
