The answer requires a computer program, because no hill
is at a constant slope forever. At some point, the hill
ends, and flat ground, or some other type of terrain
feature begins. Two programs that solve this problem are:
N6BV's YTAD, available from the ARRL web page or fileserver.
K6STI's TA, available from K6STI.
