US Hawks Hang Gliding Association

OK, My Question is this; Sylvia Drive is a Right Turn odd Austin Creek Road, up here in Cazadero California. How do I calculate the Average Grade of Sylvia road from where Silvia road T's into Austin creek road up to where My Mother livs; 55 Sylvia Drive?

Ok please comment on what I will say regarding how to Determine the Grade of Sylvia Drive from where Sylvia Begins at the Bottom. and where My Mother's House is at #55 Sylvia Drive. am thinking that I maybe should Get the location of where Sylvia Drive intersects Austin Creek road, this intersect is the Low point. Well after I have located this point, Via GPS, and the Elevation, I could then go up Sylvia, and Determine both where 55 Sylvia Drive is, and how high the Elevation is aat 55 Sylvia Drive. So if I get Both where Each Point is, and the Height. I could do the Division and get The results that I seek, Correct?

Look John Will Be coming here after He Returns from; The Point. So I am sure that if I still have not been able to determine the angle of Grade from where Sylvia Drive Intersects Austin Creek road. and up where My Mother's House is at 55 Silvia Drive.

But if any of You can give Me a little advice on My Grade Question, So Much the Better.

The link in my last post will allow one to calculate grade and express it in different ways.
Perhaps one wants their results expressed in a ratio, or percentage or degrees.
Open the link in my last post and then one can select instead of feet (shown) inches, feet, yards, miles, millimeters centimeters, meters, kilometers nautical miles, etc.
There are other options lower down that can be changed.
My best guess is that it would make more sense to choose ratio (slope) for the incline or decline and compare it with the glide slope of whichever glider one will be using.
