Geoffrey,
Thanks.

The formula for the asimuth in NA seems a little
more complicated than the one
taught by PE. I don't know what is the reason for this more complicated
formula.
All Russian books use even simpler formula:
sin A=(cos Lat sin LHA)/cos h.
where A is the asimuth, h is the altitude.
That's what I use.
It requires 3 inputs of angles to the calculator (without memory) while PS
requires 5
and NA requires 6.

There are also modified Russian formulas optimized for the calculator with
one memory cell (like Casio f250), however I do not use them, because
they compute asimuth first and altitude second, while I need
only altitude in most cases for land observations.

Alex.
