What is the procedure to convert true direction to magnetic direction in aviation navigation?
Use the isogonic lines closest to the route and estimate the average declination on the route, corrected for annual variation.
Use the procedure described in Section 4.2 to convert from true direction to magnetic direction.
Use the compass to measure the magnetic direction directly.
Use the interior scale of the protractor to measure the magnetic direction.
a) I and II are correct.
b) II and III are correct.
c) I and IV are correct.
d) II and IV are correct.

A resposta correta é a alternativa (c) I e IV estão corretas. O procedimento para converter a direção verdadeira em direção magnética na navegação aérea é usar as linhas isogônicas mais próximas da rota e estimar a declinação média na rota, corrigida para a variação anual. Em seguida, utiliza-se a escala interna do transferidor para medir a direção magnética.
