How do you get the calculation of 39x3? That's assuming 3 miles per thousand feet, but at what speed and descent rate is this?
As for the third question (related to the second), you can figure out if you're basically aligned with the runway using the GPS. Just put yourself inside the cone and you're aligned. This is how I generally fly - I still haven't figured out how to use the radios properly in commercial aircraft so I end up lining myself up using the GPS.
