There's a question in the JAA exams that runs like this:
Q. The database of a Flight Management System (FMS) is organised in such a way that the pilot can:
(A) read and write at any time in the database
(B) insert navigation data between two database updates
(C) modify the data in the database between two updates
(D) modify the database every 14 days
...and the given answer is (B). In struggling to explain why I have quickly reached the limits of my knowledge and started to struggle with assumptions. Any knights in shining armour that understand how the FMS works please could you have a look at
our forum and see if you can give me a better perspective?
