Can you determine the direction of travel of an amateur satellite's path merely by whether it is ascending or descending?
These current amateur radio exam questions seem weird to me - I mean, our AO-51 can ascend from the North or the South...
What is the direction of an ascending pass for an amateur satellite? A. From west to east B. From east to west C. From south to north D. From north to south
What is the direction of a descending pass for an amateur satellite? A. From north to south B. From west to east C. From east to west D. From south to north

Clint, Remember this one for your Extra exam...
Ascending passes cross the equator going south to north. Descending passes cross the equator going north to south. So the answer to the first question would be C and the answer to the second question would be A.

Funny you should mention this. Just for the exercise (and to see how I would measure up to US standards without any study), I tried a practice Extra exam on the ARRL web site, and this question came up (I got it right, BTW :) ).
And for the record, had that been a real US exam, I would have passed easily. :)

What's funny with those questions is that all you need is Technician privileges to work satellites and yet the questions are in the Extra part. I'm not complaining though, as this will make my test easier when I'll be ready to take it.

See the typical passes of the ISS on the web page below. It shows the geometry of the 6 to 7 passes per day we get. We use these two images to show how consistent these passes are. They are about 30% down the page.
