Question 519Navigation General

The correct answer is T. A NAVAREA warning carries a number in the format YYYY/NN, where YYYY represents the year and NN represents the consecutive number of the warning within that year. The number 1986/87 indicates that this is the 87th NAVAREA warning issued in 1986. The other answer choices (A, B, C, D) do not correspond to the format of a NAVAREA warning number, and therefore are incorrect.
