this you can be sure that the flight path ove

thereby the shortest one. The well known

describe this height (Alt a.WP) as the height
above the fastest glide path to goal . The
pre-calculated arrival height assumes that
there is neither lift nor sink along the flight
path and that the wind remains constant.

approach to the WP, this height will show 0 when the pilot should be able to reach the goal
by flying at the best glide speed. Every meter above that means a greater safety margin. As
soon as Alt above WP or Alt above BG are showing positive, both fields will change to

With a good thermal, it makes sense to begin the final glide if Alt a WP shows
The Alt a. BG then shows him/her how much height he/she will have available as se
to use if necessary, to compensate for unexpected sink. Under no circumstances should
one go ahead and fly towards goal if the Alt a BG (Height) shows zero or negative numbers

many well-known thermal sources as waypoints along a route. The pilot does not have to
feel compelled to reach these waypoints; at times he/she may be high enough to jump a
waypoint on a route, and another time he/she has already found the thermal several
kilometres before reaching the waypoint. Of course there is still the option of looking
other, possibly closer, waypoints without leaving the route one is on by using the Goto
function. Altogether the Flytec 5030 GPS can have up to 20 routes set. The same wayp
