Dear friends and administrator,

Hi. New to the forum. Currently doing my CPL and the next paper will be navigations. I thought it will be a better idea to start to learn to use the jeppesen airway manuals early as I m quite comfortable with the AIP already.

But I realized that for example the determination of BOD for Brisbane illustrated in the textbook, the values for the l attitudes is not the same (though not very much different) as the one in ersa. And for some aerodromes, there are no values for lattitudes/coordinates in the jeppesen airway manual.

is it possible if someone can shed some light on where we can get the values in the airway manuals?

thank you
