AP in the east.

Bob,

Also, are the Ap. longitude figures correct that I provided?

Thank you,

Roland

Sorry, yes.

I'm confused.  I started to plot assuming long. are DR not Assumed position. As I showed in my example above, I uised AP longitude to make LHA even to make it easier to use Pub.229. And so far it works in Bob's example. But if Long in Bob's example are AP so how you can plot DR position using DR latitude and AP longitude? Again, I thought both values are for DR
